Safety and reliability: timestamped snapshot names, safer LUKS open via stdin, read-only filesystem-aware mounts, VG free-space preflight in GUI; CLI strict mode and file-level snapshot sizing; README updates

Issues fixed:
1. Source widget now correctly switches between combobox and listbox
2. Mode changes properly refresh and show correct source options
3. Added better logging to track widget switches
4. Clear selections when switching modes
5. Force UI update after widget changes

Now:
- LV modes (lv_to_borg, files_to_borg) show multi-select listbox
- VG modes (vg_to_borg) show single-select combobox
- Widget switching works correctly when changing modes
- Borg settings appear for all Borg modes

-# System Backup to External M.2 SSD
+# Enhanced Simple LVM Backup System with Borg Support
 
-A comprehensive backup solution for Linux systems that provides both GUI and command-line interfaces for cloning your internal drive to an external M.2 SSD.
+A reliable, straightforward backup system for LVM-enabled Linux systems. Born from the need for simple, dependable backups without complex logic that can cause system issues.
+
+## Philosophy
+
+**Simple is better.** This system does exactly three things:
+1. Create LVM snapshot
+2. Copy data (dd/pv for raw, Borg for repositories)
+3. Clean up snapshot
+
+No complex migration logic, no fancy features that can break. Just reliable backups.
 
 ## Features
 
-## Features
+### Five Backup Modes
 
-- **GUI Interface**: User-friendly graphical interface built with Python Tkinter
+- **LV → LV**: Update existing logical volume backups
-- **Command Line Interface**: Full CLI support for automated and scripted operations
+- **LV → Raw**: Create fresh backups on raw devices
-- **Smart Drive Detection**: Automatically detects internal drive and external M.2 SSDs
+- **VG → Raw**: Clone entire volume groups with LVM metadata
-- **Full System Backup**: Complete drive cloning with dd for exact system replication
+- **LV → Borg**: Backup logical volume **block device** to Borg repository (preserves exact block-level state)
-- **Smart Sync Backup**: ⚡ NEW! Fast incremental backups using rsync for minor changes
+- **VG → Borg**: Backup **all block devices** from volume group to Borg repository
-- **Change Analysis**: Analyze filesystem changes to recommend sync vs full backup
+
-- **Restore Functionality**: Complete system restore from external drive
+### Two Interfaces
-- **Portable Tools**: Backup tools survive on external drive and remain accessible after cloning
+
-- **Reboot Integration**: Optional reboot before backup/restore operations
+- **GUI**: `simple_backup_gui.py` - User-friendly interface with Borg configuration
-- **Progress Monitoring**: Real-time progress display and logging
+- **CLI**: `enhanced_simple_backup.sh` - Command-line power user interface
-- **Safety Features**: Multiple confirmations and drive validation
+
-- **Desktop Integration**: Create desktop shortcuts for easy access
+## Quick Start
+
+### 1. See Available Options
+```bash
+sudo ./list_drives.sh
+```
+
+### 2. Choose Your Backup Mode
+
+**Update existing backup:**
+```bash
+sudo ./enhanced_simple_backup.sh lv-to-lv /dev/internal-vg/root /dev/backup-vg/root
+```
+
+**Fresh backup to external drive:**
+```bash
+sudo ./enhanced_simple_backup.sh lv-to-raw /dev/internal-vg/root /dev/sdb
+```
+
+**Clone entire system:**
+```bash
+sudo ./enhanced_simple_backup.sh vg-to-raw internal-vg /dev/sdb
+```
+
+**Use the GUI:**
+```bash
+sudo python3 simple_backup_gui.py
+```
+
+**Borg repository backups (block-level):**
+```bash
+# Create new Borg repo and backup LV as block device
+sudo ./enhanced_simple_backup.sh lv-to-borg /dev/internal-vg/root /path/to/borg/repo --new-repo --encryption repokey --passphrase mypass
+
+# Backup entire VG as multiple block devices to existing repo
+sudo ./enhanced_simple_backup.sh vg-to-borg internal-vg /path/to/borg/repo --passphrase mypass
+```
+
+**Key Difference:**
+- **LV → Borg**: Stores one snapshot as `{lv_name}.img` in a single archive
+- **VG → Borg**: Creates separate archives for each LV (space-efficient, processes one LV at a time)
+
+## Files

-
-## Usage
-
-### GUI Application
-
-Launch the graphical backup manager:
-
-```bash
-python3 backup_manager.py
-```
-
-**Features:**
-- Automatic drive detection and classification
-- Source and target drive selection with smart defaults
-- Real-time progress monitoring
-- **Backup Modes**:
-  - **Smart Sync Backup**: ⚡ Fast incremental backup using rsync (requires existing backup)
-  - **Analyze Changes**: Analyze what has changed since last backup
-  - **Start Backup**: Full drive clone (immediate backup while system running)

-
-### Command Line Script
-
-For command-line usage:
-
-```bash
-# List available drives
-./backup_script.sh --list
-
-# Analyze changes without performing backup
-./backup_script.sh --analyze --target /dev/sdb
-
-# Smart sync backup (fast incremental update)  
-sudo ./backup_script.sh --sync --target /dev/sdb
-
-# Perform full backup with specific drives
-sudo ./backup_script.sh --source /dev/nvme0n1 --target /dev/sda
-
-# Restore from external to internal (note the restore flag)
-sudo ./backup_script.sh --restore --source /dev/sda --target /dev/nvme0n1
-
-# Or more simply in restore mode (source/target are swapped automatically)
-sudo ./backup_script.sh --restore --source /dev/nvme0n1 --target /dev/sda
-
-# Create desktop entry
-./backup_script.sh --desktop
-
-# Launch GUI from script

-```
-
-### Desktop Integration
-
-Create a desktop shortcut:
-
-```bash
-./backup_script.sh --desktop
-```
-
-This creates a clickable icon on your desktop that launches the backup tool.
-
-## Restore Operations
-
-### When to Restore
-- **System Failure**: Internal drive crashed or corrupted
-- **System Migration**: Moving to new hardware
-- **Rollback**: Reverting to previous system state
-- **Testing**: Restoring test environment
-
-### How to Restore
-
-#### GUI Method
-1. **Connect External Drive**: Plug in your M.2 SSD with backup
-2. **Launch GUI**: `python3 backup_manager.py`
-3. **Check Drive Selection**: 
-   - Source should be external drive (your backup)
-   - Target should be internal drive (will be overwritten)
-4. **Use Swap Button**: If needed, click "Swap Source↔Target"
-5. **Choose Restore Mode**:
-   - **"Restore from External"**: Immediate restore
-   - **"Reboot & Restore"**: Reboot then restore (recommended)
-
-#### Command Line Method
-```bash
-# Restore with automatic drive detection
-sudo ./backup_script.sh --restore
-
-# Restore with specific drives
-sudo ./backup_script.sh --restore --source /dev/sda --target /dev/nvme0n1
-```
-
-### ⚠️ Restore Safety Warnings
-- **Data Loss**: Target drive is completely overwritten
-- **Irreversible**: No undo after restore starts
-- **Multiple Confirmations**: System requires explicit confirmation
-- **Drive Verification**: Double-check source and target drives
-- **Boot Issues**: Ensure external drive contains valid system backup
-
-## Portable Tools (Boot from External M.2)
-
-### Setup Portable Tools
-Run this once to set up backup tools on your external M.2 SSD:
-
-```bash
-./setup_portable_tools.sh
-```
-
-This will:
-- Create a 512MB tools partition on your external drive
-- Install backup tools that survive cloning operations
-- Set up automatic tool restoration after each backup
-
-### Using Portable Tools
-
-#### When Booted from External M.2 SSD:
-
-1. **Access Tools**:
-   ```bash
-   # Easy access helper
-   ./access_tools.sh
-   
-   # Or manually:
-   sudo mount LABEL=BACKUP_TOOLS /mnt/tools
-   cd /mnt/tools/backup_system
-   ./launch_backup_tools.sh
-   ```
-
-2. **Restore Internal Drive**:
-   - Launch backup tools from external drive
-   - External drive (source) → Internal drive (target)
-   - Click "Reboot & Restore" for safest operation
-
-3. **Create Desktop Entry**:
-   ```bash
-   cd /mnt/tools/backup_system
-   ./create_desktop_entry.sh
-   ```
-
-### Disaster Recovery Workflow
-
-1. **Normal Operation**: Internal drive fails
-2. **Boot from External**: Use M.2 SSD as boot drive
-3. **Access Tools**: Run `./access_tools.sh`
-4. **Restore System**: Use backup tools to restore to new internal drive
-5. **Back to Normal**: Boot from restored internal drive
 
 ## Safety Features
 
-- **Drive Validation**: Prevents accidental overwriting of wrong drives
+- Clear confirmations before destructive operations
-- **Size Checking**: Ensures target drive is large enough
+- Automatic snapshot cleanup on errors
-- **Confirmation Prompts**: Multiple confirmation steps before destructive operations
+- Emergency stop functionality (GUI)
-- **Mount Detection**: Automatically unmounts target drives before backup
+- Input validation and error handling
-- **Progress Monitoring**: Real-time feedback during backup operations
+- Timestamped snapshot names to avoid collisions on retries
+- Read-only snapshot mounts with filesystem-aware safety flags (ext4: noload, xfs: norecovery)
+- Strict shell mode in CLI (set -euo pipefail) for reliable error propagation
+- Pre-flight checks for VG free space before creating snapshots
 
-## File Structure
+## What This System Does NOT Do
 
-```
+- Complex migration between different LVM setups

-## Smart Sync Technology ⚡
+For those features, use dedicated tools like Borg Backup, CloneZilla, or rsync.
 
-The backup system now includes advanced **Smart Sync** functionality that dramatically reduces backup time for incremental updates:
+## Why This Approach?
 
-### How Smart Sync Works
+Previous versions of this project included complex migration logic that occasionally caused system issues. This version returns to basics:
 
-1. **Analysis Phase**: Compares source and target filesystems to determine changes
+✅ Uses standard LVM commands only  
-2. **Decision Engine**: Recommends sync vs full clone based on amount of changes:
+✅ Minimal chance of errors  
-   - **< 2GB changes**: Smart sync recommended (much faster)
+✅ Easy to understand and debug  
-   - **2-10GB changes**: Smart sync beneficial 
+✅ Predictable behavior  
-   - **> 10GB changes**: Full clone may be more appropriate
+✅ No hidden "smart" features  
-3. **Sync Operation**: Uses rsync to transfer only changed files and metadata
 
-### Smart Sync Benefits
+Notes and limitations:
+- Multi-PV VGs: Raw clone and VG→Borg flows require careful handling. If a VG spans multiple PVs, the simple raw clone path is not supported; use block-level per-LV backups or full-disk cloning tools.
+- File-level backups are for data safety, not bootability. Use block-level backups for exact bootable images.
+- Ensure the Borg repository is not located on the same LV being snapshotted.
 
-- **Speed**: 10-100x faster than full clone for minor changes
+## Recovery
-- **No Downtime**: System remains usable during sync operation
-- **Efficiency**: Only transfers changed data, preserving bandwidth and storage wear
-- **Safety**: Preserves backup tools and maintains full system consistency
 
-### When to Use Smart Sync vs Full Clone
+### From LV Backup
+Mount the backup LV and copy files, or use it to restore your system.
 
-**Use Smart Sync when:**
+### From Raw Device Backup  
-- You have an existing backup on the target drive
+Boot directly from the device, or restore using dd in reverse.
-- Regular incremental updates (daily/weekly backups)
-- Minimal system changes since last backup
-- You want faster backup with minimal downtime
 
-**Use Full Clone when:**
+### From VG Clone
-- First-time backup to a new drive
+Import the volume group or boot directly from the cloned device.
-- Major system changes (OS upgrade, large software installations)
-- Corrupted or incomplete previous backup
-- Maximum compatibility and reliability needed
-
-### Smart Sync Usage
-
-**GUI Method:**
-1. Click "Analyze Changes" to see what has changed
-2. Review the recommendation and estimated time savings
-3. Click "Smart Sync Backup" to perform incremental update
-
-**Command Line:**
-```bash
-# Analyze changes first
-./backup_script.sh --analyze --target /dev/sdb
-
-# Perform smart sync
-sudo ./backup_script.sh --sync --target /dev/sdb
-```
-
-## Traditional Full Backup
-
-For comprehensive system backup, the system uses proven `dd` cloning technology:
-
-### Backup Process
-1. **Drive Detection**: Automatically scans for available drives
-2. **Auto-Selection**: Internal drive as source, external as target
-3. **Operation Selection**: Choose backup or restore mode
-4. **Validation**: Confirms drives exist and are different
-5. **Execution**: Uses `dd` command to clone entire drive
-6. **Progress**: Shows real-time progress and logging
-
-### Backup vs Restore
-- **Backup**: Internal → External (preserves your system on external drive)
-- **Restore**: External → Internal (overwrites internal with backup data)
-- **Swap Button**: Easily switch source/target for restore operations
-
-### Reboot vs Immediate Operations
-- **Immediate**: Faster start, but system is running (potential file locks)
-- **Reboot Mode**: System restarts first, then operates (cleaner, more reliable)
-- **Recommendation**: Use reboot mode for critical operations
-
-### Reboot & Backup Mode
-1. **Script Creation**: Creates a backup script for post-reboot execution
-2. **Reboot Scheduling**: Schedules system reboot
-3. **Auto-Execution**: Backup starts automatically after reboot
-4. **Notification**: Shows completion status
-
-### Command Line Mode
-- Direct `dd` cloning with progress monitoring
-- Comprehensive logging to `/var/log/system_backup.log`
-- Drive size validation and safety checks
-
-## Technical Details
-
-### Backup Method
-- Uses `dd` command for bit-perfect drive cloning
-- Block size optimized at 4MB for performance
-- `fdatasync` ensures all data is written to disk
-
-### Drive Detection
-- Uses `lsblk` to enumerate block devices
-- Filters for actual disk drives
-- Shows drive sizes for easy identification
-
-### Safety Mechanisms
-- Root privilege verification
-- Block device validation
-- Source/target drive comparison
-- Mount status checking
-- Size compatibility verification
-
-## Troubleshooting
-
-### Common Issues
-
-1. **Permission Denied**
-   ```bash
-   # Run with sudo for drive operations
-   sudo python3 backup_manager.py
-   ```
-
-2. **Drive Not Detected**
-   ```bash
-   # Check if drive is connected and recognized
-   lsblk
-   dmesg | tail
-   ```
-
-3. **Backup Fails**
-   ```bash
-   # Check system logs
-   sudo journalctl -f
-   tail -f /var/log/system_backup.log
-   ```
-
-### Performance Tips
-
-- Use USB 3.0+ connection for external M.2 SSD
-- Ensure sufficient power supply for external enclosure
-- Close unnecessary applications during backup
-- Use SSD for better performance than traditional HDD
-
-## Security Considerations
-
-- **Data Destruction**: Target drive data is completely overwritten
-- **Root Access**: Scripts require elevated privileges
-- **Verification**: Always verify backup integrity after completion
-- **Testing**: Test restore process with non-critical data first
-
-## Limitations
-
-- Only works with block devices (entire drives)
-- Cannot backup to smaller drives
-- Requires manual drive selection for safety
-- No incremental backup support (full clone only)

+# Simple LVM Backup System
+
+**A much simpler, safer approach to LVM backups.**
+
+After issues with complex backup systems, this is a return to basics:
+- Simple LVM snapshot creation
+- Direct block-level copy with dd/pv
+- Minimal logic, maximum reliability
+
+## What This Does
+
+1. **Creates an LVM snapshot** of your source volume
+2. **Copies it block-for-block** to your target drive
+3. **Cleans up the snapshot** when done
+
+That's it. No complex migration logic, no fancy features that can break.
+
+## Quick Start
+
+### 1. See what's available
+```bash
+sudo ./list_drives.sh
+```
+
+### 2. Run a simple backup
+```bash
+sudo ./simple_backup.sh /dev/your-vg/your-lv /dev/your-target-drive
+```
+
+### 3. Or use the GUI
+```bash
+sudo python3 simple_backup_gui.py
+```
+
+## Examples
+
+**Backup your root volume to an external SSD:**
+```bash
+sudo ./simple_backup.sh /dev/internal-vg/root /dev/sdb
+```
+
+**Backup your home volume:**
+```bash
+sudo ./simple_backup.sh /dev/internal-vg/home /dev/nvme1n1
+```
+
+## Important Notes
+
+⚠️ **WARNING: The target drive will be completely overwritten!**
+
+- Always run as root (`sudo`)
+- Target device will lose ALL existing data
+- Make sure target device is unmounted before backup
+- The backup is a complete block-level clone
+- You need at least 1GB free space in your volume group for the snapshot
+
+## How It Works
+
+This is exactly what happens, no hidden complexity:
+
+1. `lvcreate -L1G -s -n backup_snap /dev/vg/lv` - Create snapshot
+2. `pv /dev/vg/backup_snap | dd of=/dev/target bs=4M` - Copy data  
+3. `lvremove -f /dev/vg/backup_snap` - Remove snapshot
+
+## Files
+
+- `simple_backup.sh` - Command-line backup script
+- `simple_backup_gui.py` - Simple GUI version
+- `list_drives.sh` - Helper to show available drives
+
+## Why This Approach?
+
+The previous complex scripts had too much logic and caused system issues. This approach:
+
+- ✅ Uses standard LVM commands
+- ✅ Minimal chance of errors
+- ✅ Easy to understand and debug
+- ✅ Does exactly what you expect
+- ✅ No hidden "smart" features
+
+## Recovery
+
+To boot from your backup:
+1. Connect the external drive
+2. Boot from it directly, or
+3. Use it as a recovery drive to restore your system
+
+## Requirements
+
+- LVM-enabled system
+- Root access
+- Python 3 + tkinter (for GUI)
+- `pv` command (optional, for progress display)
+
+## If Something Goes Wrong
+
+The script will try to clean up snapshots automatically. If it fails:
+
+```bash
+# List any remaining snapshots
+sudo lvs | grep snap
+
+# Remove manually if needed
+sudo lvremove /dev/vg/snapshot_name
+```
+
+## No More Complex Features
+
+This system intentionally does NOT include:
+- Automatic drive detection with complex logic
+- Migration between different LVM setups  
+- Boot repair or GRUB handling
+- Multiple backup formats
+- Configuration files
+- Complex error handling
+
+If you need those features, use dedicated tools like CloneZilla or Borg Backup.
+
+This is for simple, reliable block-level LVM backups. Nothing more, nothing less.

+# Internal NVMe Boot Repair Summary
+
+## Problem
+After resizing the home partition, the internal NVMe drive (nvme0n1) was showing a "reset system" message on boot, suspected GRUB issue.
+
+## Root Cause
+The GRUB bootloader needed to be reinstalled after the partition resize, and boot failure flags needed to be cleared from the GRUB environment.
+
+## Solution Applied
+
+### 1. Updated GRUB Configuration
+```bash
+sudo update-grub
+```
+- Regenerated `/boot/grub/grub.cfg` with current system configuration
+- Found and registered kernel images: 6.8.0-84 and 6.8.0-83
+
+### 2. Reinstalled GRUB Bootloader
+```bash
+sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=ubuntu --recheck /dev/nvme0n1
+```
+- Installed GRUB to internal NVMe drive
+- Files installed to `/boot/efi/EFI/ubuntu/`:
+  - shimx64.efi (secure boot shim)
+  - grubx64.efi (GRUB bootloader)
+  - grub.cfg (initial configuration)
+
+### 3. Cleared Boot Failure Flags
+```bash
+sudo grub-editenv - unset recordfail
+sudo grub-editenv - unset boot_success
+```
+- Removed any boot failure tracking that might cause "reset system" message
+- GRUB environment now clean
+
+## Current System Status
+
+### Boot Configuration
+- **Currently Running From**: External USB M.2 (sda - migration-vg)
+  - Root: `/dev/mapper/migration-vg-root` → mounted as `/`
+  - Home: `/dev/mapper/luks-home-internal` (on external) → mounted as `/home`
+  
+- **Internal Drive**: NVMe (nvme0n1 - internal-vg) - NOW BOOTABLE
+  - EFI: `/dev/nvme0n1p1` → mounted as `/boot/efi`
+  - Boot: `/dev/internal-vg/boot` → mounted as `/boot`
+  - Root: `/dev/internal-vg/root` (ready but not currently root)
+  - Home: `/dev/internal-vg/home` (LUKS encrypted, not currently mounted)
+
+### EFI Boot Entries
+```
+BootOrder: 0001,001C,001B,0000,... (Ubuntu is first)
+Boot0001* Ubuntu - Points to /boot/efi/EFI/ubuntu/shimx64.efi
+Boot001F* USB HDD - Currently active (external M.2)
+```
+
+### Partition Layout
+**Internal NVMe (nvme0n1):**
+- nvme0n1p1: 511MB EFI partition (757B-A377)
+- nvme0n1p2: 476.4GB LVM (internal-vg)
+  - internal-vg/root: 56GB ext4
+  - internal-vg/boot: 2GB ext4
+  - internal-vg/home: 404GB LUKS encrypted
+  - internal-vg/swap: 8GB swap
+
+**External M.2 (sda):**
+- sda1: EFI partition
+- sda2: 476.4GB LVM (migration-vg)
+  - Identical structure to internal-vg
+
+## Testing the Fix
+
+### To Boot from Internal Drive:
+1. **Shutdown the system**:
+   ```bash
+   sudo shutdown -h now
+   ```
+
+2. **Disconnect the external USB M.2 drive** (sda)
+
+3. **Power on the system**
+
+4. **Expected Behavior**:
+   - System should boot from internal NVMe
+   - No more "reset system" message
+   - GRUB menu should appear normally
+   - System will boot into internal-vg volumes
+
+### If You Want to Keep Both Drives Connected:
+1. Change boot order in BIOS to prefer internal NVMe over USB
+2. Or use BIOS boot menu (usually F12) to manually select internal drive
+
+## Verification Commands
+
+Check internal drive boot readiness:
+```bash
+./verify_internal_boot.sh
+```
+
+Check EFI boot entries:
+```bash
+efibootmgr -v
+```
+
+Verify GRUB configuration:
+```bash
+sudo cat /boot/grub/grub.cfg | grep -A5 "menuentry"
+```
+
+## Important Notes
+
+1. **Both drives have identical LVM structure** (internal-vg and migration-vg)
+   - Both have root, boot, home, and swap volumes
+   - Home volumes are both LUKS encrypted
+
+2. **Current /etc/fstab** is configured for internal-vg:
+   ```
+   /dev/internal-vg/root → /
+   /dev/internal-vg/boot → /boot
+   /dev/internal-vg/home → /home (via LUKS)
+   ```
+   This is correct for booting from internal drive.
+
+3. **System is currently running from external drive** due to boot order/USB boot
+   - This is temporary for testing
+   - Internal drive is fully configured and ready
+
+4. **No data loss risk** - all changes were to bootloader configuration only
+
+## Next Steps
+
+Once you've verified the internal drive boots correctly:
+
+1. **Run the backup** to clone internal-vg to migration-vg:
+   ```bash
+   sudo ./lvm_block_backup.sh
+   ```
+   This will create a block-level backup of internal drive to external drive.
+
+2. **Keep external drive as emergency backup**:
+   - Can boot from it if internal drive fails
+   - Already has identical LVM structure

+# Drive Selection Reference
+
+Based on your system screenshots, here's the correct drive mapping:
+
+## Current System Layout (from screenshots):
+
+### Available Drives:
+- **`/dev/nvme0n1`** - 476.9G KXG6AZNV512G TOSHIBA
+  - ✅ **INTERNAL DRIVE** (source)
+  - This is your current system with:
+    - nvme0n1p1: 58GB Linux filesystem (root)
+    - nvme0n1p2: 512MB EFI system  
+    - nvme0n1p3: 417GB Linux filesystem (home)
+
+- **`/dev/sda`** - 476.9G Tech JMicron
+  - ✅ **EXTERNAL M.2 SSD** (target)
+  - This should be selected as migration TARGET
+  - Will be completely wiped and converted to LVM
+
+- **`/dev/sdb`** - 119.3G Extreme Pro SanDisk
+  - 🔧 **USB STICK** (migration tools)
+  - This USB stick with the migration tools
+  - Should NOT be selected for migration
+
+## Correct Migration Configuration:
+
+```
+Source (Internal): /dev/nvme0n1 → Target (External): /dev/sda
+```
+
+## What the Enhanced Script Now Does:
+
+1. **Excludes USB stick** - Won't offer /dev/sdb as an option
+2. **Shows drive details** - Displays size, model, USB detection
+3. **Suggests configuration**:
+   - Internal: /dev/nvme0n1 (NVMe drives are typically internal)
+   - External: /dev/sda (USB-connected drives are typically external)
+4. **User confirmation** - Asks you to confirm before proceeding
+5. **Final safety check** - Shows exactly what will be wiped
+6. **Type 'YES' confirmation** - Prevents accidental data loss
+
+## Migration Process:
+
+1. **Boot from USB** (/dev/sdb)
+2. **Run migration script**
+3. **Script will suggest**:
+   - Internal: /dev/nvme0n1 (476.9G TOSHIBA)
+   - External: /dev/sda (476.9G JMicron) 
+4. **Confirm selection**
+5. **Type 'YES' to proceed**
+
+This should prevent the wrong drive selection issue you encountered!

+# Internal Drive Recovery - Complete Configuration
+
+## ✅ What Was Fixed
+
+Your internal NVMe drive is now **fully configured to boot independently** from the external M.2 backup drive.
+
+### Changes Made:
+
+#### 1. **Fixed LUKS Encryption Configuration** (`/etc/crypttab`)
+**Problem**: Both internal and external drives have the same LUKS UUID, causing the system to mount home from whichever drive it found first (which was the external).
+
+**Solution**: Changed `/etc/crypttab` to use device path instead of UUID:
+```bash
+# OLD (using UUID - ambiguous):
+luks-home-internal UUID=e4d30f4f-3aac-48a7-a1ca-83539598555b none luks
+
+# NEW (using device path - specific):
+luks-home-internal /dev/internal-vg/home none luks
+```
+
+**Backup**: `/etc/crypttab.backup.20251006`
+
+#### 2. **Updated Initramfs**
+Regenerated the initial RAM filesystem to include the new crypttab configuration:
+```bash
+sudo update-initramfs -u -k all
+```
+This ensures the system uses the internal drive's home partition during boot.
+
+#### 3. **Reinstalled GRUB Bootloader**
+```bash
+sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=ubuntu
+```
+- Created Ubuntu EFI boot entry (Boot0001)
+- Installed to internal drive's EFI partition (nvme0n1p1)
+
+#### 4. **Set EFI Boot Order**
+```bash
+sudo efibootmgr -o 0001,001C,001B,0000,...
+```
+- **Ubuntu (Boot0001)** is now the FIRST boot option
+- System will boot from internal drive by default
+- External drive boot entries (001F USB HDD) are lower priority
+
+## 📊 Current System Configuration
+
+### Internal NVMe Drive (nvme0n1) - PRIMARY
+```
+nvme0n1 (476.9 GB)
+├─ nvme0n1p1       → /boot/efi (EFI partition, 511MB)
+└─ nvme0n1p2       → internal-vg (LVM)
+   ├─ root (56GB)  → / (root filesystem)
+   ├─ boot (2GB)   → /boot (kernel images)
+   ├─ home (404GB) → /home (LUKS encrypted) ← NOW CONFIGURED
+   └─ swap (8GB)   → swap
+```
+
+### External M.2 USB (sda) - BACKUP
+```
+sda (476.9 GB)
+├─ sda1            → EFI partition (unmounted)
+└─ sda2            → migration-vg (LVM)
+   ├─ root (56GB)  → (unmounted)
+   ├─ boot (2GB)   → (unmounted)
+   ├─ home (404GB) → (unmounted, LUKS encrypted)
+   └─ swap (8GB)   → (inactive)
+```
+
+### Mount Points (After Reboot)
+```
+/dev/internal-vg/root              → /
+/dev/internal-vg/boot              → /boot
+/dev/mapper/luks-home-internal     → /home  (from internal-vg/home)
+/dev/internal-vg/swap              → swap
+/dev/nvme0n1p1                     → /boot/efi
+```
+
+## 🔐 LUKS Encryption Details
+
+Both drives have identical LUKS setup:
+- **UUID**: e4d30f4f-3aac-48a7-a1ca-83539598555b (same on both!)
+- **Type**: LUKS2
+- **Cipher**: aes-xts-plain64
+- **Keysize**: 512 bits
+
+The system now uses device path (`/dev/internal-vg/home`) instead of UUID to ensure it mounts the internal drive's home partition.
+
+## 🚀 Testing Instructions
+
+### Test 1: Boot with Both Drives Connected
+```bash
+sudo reboot
+```
+**Expected**: System boots from internal drive, uses internal home partition.
+
+**Verify after boot**:
+```bash
+mount | grep -E "/ |/boot|/home"
+# Should show all mounts from internal-vg
+```
+
+### Test 2: Boot with ONLY Internal Drive (Full Independence Test)
+```bash
+# 1. Shutdown system
+sudo shutdown -h now
+
+# 2. Physically disconnect external USB M.2 drive (sda)
+
+# 3. Power on system
+
+# Expected: System boots completely from internal NVMe
+```
+
+**If everything works**, you'll have:
+- GRUB menu appears (no "reset system" message should appear after first clean boot)
+- System boots to login screen
+- Can log in with encrypted home partition
+- All data accessible from internal drive
+
+## 🔍 Verification Commands
+
+After reboot, run these to verify internal drive is being used:
+
+```bash
+# Check what's mounted where
+lsblk -o NAME,SIZE,TYPE,MOUNTPOINT
+
+# Verify home is from internal drive
+sudo cryptsetup status luks-home-internal
+# Should show: device: /dev/mapper/internal--vg-home
+
+# Check boot order
+efibootmgr | grep -A1 BootOrder
+# Should show: BootOrder: 0001,... (Ubuntu first)
+
+# Verify all internal volumes
+mount | grep internal-vg
+```
+
+## 📝 Configuration Files Modified
+
+1. **`/etc/crypttab`** - Updated to use internal-vg/home device path
+   - Backup: `/etc/crypttab.backup.20251006`
+
+2. **`/boot/initrd.img-*`** - Regenerated with new crypttab
+
+3. **`/boot/efi/EFI/ubuntu/`** - GRUB bootloader reinstalled
+
+4. **UEFI NVRAM** - Boot order updated (Boot0001 first)
+
+## 🛡️ About the "Reset System" Message
+
+The "reset system" message you saw **before GRUB** is a **Lenovo BIOS/UEFI firmware notification**, not a GRUB error.
+
+### Why it appears:
+- BIOS detected improper shutdown or boot failure
+- Partition resize triggered hardware change detection
+- BIOS boot counter wasn't acknowledged
+
+### How to clear it:
+**Option 1** (Easiest): Enter BIOS setup during boot
+- Press **F1** during Lenovo logo
+- Just enter BIOS (don't need to change anything)
+- Press **F10** to save and exit
+- This acknowledges the BIOS warning
+
+**Option 2**: Clean shutdown cycle
+```bash
+sudo shutdown -h now
+# Wait 10 seconds
+# Power on
+# BIOS may clear flag after successful boot
+```
+
+**Option 3**: Wait for successful boots
+- After 2-3 successful clean boots, BIOS usually clears the flag automatically
+
+## ✨ What You Can Do Now
+
+### 1. Use Internal Drive Normally
+Your internal NVMe is fully functional and independent. You can:
+- Boot without external drive connected
+- Use system normally with all data on internal drive
+- Keep external drive disconnected
+
+### 2. Run the Backup
+Now you can create a proper block-level backup:
+```bash
+cd ~/Nextcloud/entwicklung/Werkzeuge/backup_to_external_m.2
+sudo ./lvm_block_backup.sh
+```
+
+This will clone internal-vg to migration-vg on the external drive.
+
+### 3. Keep External as Emergency Backup
+The external drive can serve as:
+- **Bootable backup**: If internal fails, boot from external
+- **Recovery system**: Access data if internal has issues
+- **Migration tool**: Already has identical LVM structure
+
+## 📚 Related Files in This Directory
+
+- `lvm_block_backup.sh` - Block-level backup script (internal → external)
+- `BOOT_FIX_SUMMARY.md` - Details about GRUB reinstallation
+- `verify_internal_boot.sh` - Boot configuration verification script
+- `clear_bios_boot_flag.sh` - BIOS message diagnostic tool
+- `README_BACKUP.md` - Backup strategy documentation
+
+## ⚠️ Important Notes
+
+1. **Same LUKS UUID**: Both drives have identical UUIDs because they were cloned. The device path in crypttab ensures the right one is used.
+
+2. **Don't mix drives during boot**: If both drives are connected and you manually select the wrong one in BIOS boot menu, the system might use the external drive instead.
+
+3. **Backup before cloning**: The `lvm_block_backup.sh` will **OVERWRITE** the external drive's volumes. Make sure any unique data on the external is backed up first.
+
+4. **Home data**: Currently your home directory data is on the external drive. After the first clean reboot, verify if you need to copy any recent data from external to internal before running the backup.
+
+## 🎯 Summary
+
+**Status**: ✅ **Internal drive is fully configured and ready**
+
+**Changes**: 
+- Crypttab uses internal drive explicitly
+- Initramfs updated
+- GRUB reinstalled
+- Boot order corrected (Ubuntu first)
+
+**Next Step**: 
+1. **Test** - Reboot to verify internal drive works
+2. **Backup** - Run `lvm_block_backup.sh` to clone to external
+3. **Normal Use** - Use internal drive, keep external as backup
+
+**BIOS Message**: Will likely clear after 1-2 clean boots or entering BIOS setup (F1)

+# LVM Block-Level Backup Tool
+
+## What This Does
+
+This tool performs a **proper** LVM snapshot backup by:
+
+1. ✅ Creating consistent LVM snapshots of your internal drive
+2. ✅ Cloning entire volumes **block-for-block** to external drive
+3. ✅ Creating an exact, bootable copy of your system
+4. ✅ Using full drive capacity efficiently
+
+## Why This Is Better
+
+- **Fast**: Block-level copying is much faster than file copying
+- **Complete**: Exact bit-for-bit copy including all metadata
+- **Bootable**: External drive can boot your system directly
+- **Space Efficient**: Uses full drive capacity, no filesystem overhead
+- **Consistent**: Snapshots ensure data consistency during backup
+
+## Usage
+
+```bash
+# Simple one-command backup
+sudo ./lvm_block_backup.sh
+```
+
+## Requirements
+
+- Both drives must have LVM setup
+- External drive volume group: `migration-vg`
+- Internal drive volume group: `internal-vg`
+- At least 6GB free space for snapshots
+
+## What Gets Backed Up
+
+- **Root volume**: Complete system, applications, configurations
+- **Home volume**: All user data (including encrypted LUKS)
+- **Boot volume**: Kernels, bootloader, boot configuration
+
+## Result
+
+After backup, your external drive contains an exact copy that can:
+- Boot independently from BIOS/UEFI menu
+- Be mounted to access files
+- Serve as complete system recovery
+
+---
+
+**Note**: The `old_scripts/` directory contains 40+ previous backup attempts that didn't work properly. This single script replaces all of them.

+# Simple and Reliable 1-to-1 Clone Solution
+
+## Problem Analysis
+
+The LVM migration failed because it introduced too much complexity:
+- Complex LVM setup with volume groups and logical volumes
+- Initramfs configuration issues with LVM modules
+- Boot loader configuration changes
+- Multiple mount points and potential failure scenarios
+
+The screenshot shows a boot failure where the system can't properly initialize, likely because the initramfs doesn't have the right LVM configuration.
+
+## Solution: Direct 1-to-1 Clone
+
+Instead of converting to LVM, create an exact bit-perfect copy that preserves your original structure:
+
+### Key Advantages:
+✅ **Preserves original encryption** - LUKS works exactly as before  
+✅ **No LVM complexity** - Simple partition structure  
+✅ **Minimal boot changes** - Only UUID updates needed  
+✅ **Reliable boot process** - Same as your working internal drive  
+✅ **Emergency fallback** - Original internal drive unchanged  
+
+## Usage Instructions
+
+### Step 1: Create the Clone
+```bash
+# Run from live USB system
+sudo ./direct_clone_backup.sh
+```
+
+This script will:
+- Detect your internal and external drives
+- Create a bit-perfect clone (using dd)
+- Update UUIDs to prevent conflicts
+- Fix /etc/fstab with new UUIDs
+- Install/repair GRUB bootloader
+- Verify the clone integrity
+
+### Step 2: Verify Boot Readiness
+```bash
+# Verify the cloned drive will boot properly
+sudo ./verify_boot_readiness.sh
+```
+
+This script checks:
+- Partition structure integrity
+- Filesystem health
+- Essential boot files presence
+- GRUB configuration
+- Boot readiness tests
+
+### Step 3: Fix Issues (if needed)
+```bash
+# If verification fails, repair the clone
+sudo ./boot_repair_tools.sh
+```
+
+Available repair options:
+- Full repair (recommended)
+- GRUB repair only
+- /etc/fstab fix only
+- Initramfs regeneration
+- Boot configuration check
+
+## What This Solution Does Differently
+
+### ❌ LVM Migration (Complex, Failed)
+- Converts partition structure to LVM
+- Requires initramfs LVM module configuration
+- Changes boot process significantly
+- Multiple potential failure points
+- Complex recovery if something goes wrong
+
+### ✅ Direct Clone (Simple, Reliable)
+- Preserves exact original structure
+- No initramfs changes needed
+- Minimal boot process changes
+- Only UUID conflicts to resolve
+- Easy recovery with original drive
+
+## Boot Process Comparison
+
+### Original Failed LVM Boot:
+1. GRUB loads → 2. Initramfs loads → 3. **FAILS** (LVM modules/config issue) → Boot failure
+
+### New Direct Clone Boot:
+1. GRUB loads → 2. Initramfs loads → 3. **WORKS** (identical to original) → LUKS password → System boots
+
+## Expected Results
+
+After running the direct clone:
+1. **Boots like original** - Same encryption, same password prompt
+2. **No reset loops** - Stable boot process
+3. **Identical experience** - Everything works as before
+4. **Safe fallback** - Original internal drive unchanged

+## Emergency Recovery
+
+If something goes wrong:
+1. Boot from original internal drive (unchanged)
+2. Run `boot_repair_tools.sh` on external drive
+3. Or re-run `direct_clone_backup.sh` to start over
+
+## Key Files Created
+
+1. **`direct_clone_backup.sh`** - Main cloning script
+2. **`verify_boot_readiness.sh`** - Boot verification tool  
+3. **`boot_repair_tools.sh`** - Emergency repair toolkit
+
+This solution avoids all the complexity that caused the LVM migration to fail while giving you a working 1-to-1 copy that boots reliably.

+=== SIMPLE 1-TO-1 CLONE INSTRUCTIONS ===
+
+IMPORTANT: Boot from this USB stick first!
+
+1. REBOOT and boot from this USB stick (Debian Live)
+
+2. Once in live system, open terminal and run:
+   cd /media/migration_tools (or wherever this partition mounts)
+   
+3. Run the clone process:
+   sudo ./direct_clone_backup.sh
+   
+4. Verify the clone:
+   sudo ./verify_boot_readiness.sh
+   
+5. If needed, repair issues:
+   sudo ./boot_repair_tools.sh
+
+This creates a working 1-to-1 copy without LVM complexity!
+
+Read SIMPLE_CLONE_SOLUTION.md for full details.

+# LVM Backup Manager
+
+## Overview
+
+LVM Backup Manager is a professional graphical interface for creating block-level backups of LVM (Logical Volume Manager) volumes. It provides an intuitive way to clone entire volume groups while maintaining data consistency through LVM snapshots.
+
+## Features
+
+* **Intuitive GUI**: Easy-to-use interface with drive selection and progress monitoring
+* **Real-time Progress**: Live progress bars and speed indicators during backup
+* **Safety Features**: Confirmation dialogs and verification tools
+* **Professional Logging**: Detailed logs with timestamps for troubleshooting
+* **Snapshot-based**: Uses LVM snapshots for consistent, live backups
+* **Block-level Cloning**: Creates exact, bootable copies of your volumes
+
+## System Requirements
+
+* Linux system with LVM2 installed
+* Python 3.x with Tkinter support
+* Root/sudo privileges for LVM operations
+* External storage device with LVM volume group
+
+## Usage
+
+### GUI Application
+```bash
+sudo lvm-backup-manager
+```
+
+### Command Line (legacy)
+```bash
+sudo lvm-block-backup
+```
+
+## How It Works
+
+1. **Detection**: Scans for available LVM volume groups
+2. **Selection**: Choose source and target volume groups
+3. **Calculation**: Estimates backup time and data size
+4. **Snapshots**: Creates consistent snapshots of source volumes
+5. **Cloning**: Performs block-level copy using dd command
+6. **Verification**: Checks filesystem integrity of backup
+7. **Cleanup**: Removes temporary snapshots
+
+## Safety Notes
+
+* **Always verify** your target drive selection
+* **Backup process will overwrite** all data on target volume group
+* **Test your backups** using the verification feature
+* **Keep multiple backup copies** for critical data
+
+## Support
+
+For issues or questions, check the log output in the GUI application or examine system logs.

-
-### Restore Internal Drive:
-1. Boot from this external drive
-2. Launch backup tools
-3. Select "Restore from External"
-4. Choose external → internal
-5. Click "Reboot & Restore"
-
-### Update Backup:
-1. Boot normally from internal drive
-2. Connect this external drive
-3. Run backup as usual
-4. Tools will be automatically preserved
-

-- Partition 1-2: System backup (bootable)
-- Last Partition: Backup tools (this)
