cleanup: Archive old complex scripts and documentation

- Move all old complex backup scripts to old_scripts/
- Archive previous documentation versions
- Clean up temporary files and debian packages
- Update README to focus on new simple system
- Keep only the enhanced simple backup system in main directory

Main directory now contains only:
- simple_backup_gui.py (GUI interface)
- enhanced_simple_backup.sh (CLI interface)
- list_drives.sh (helper)
- simple_backup.sh (basic CLI)
- SIMPLE_BACKUP_README.md (detailed docs)
- README.md (project overview)

+
+Your internal NVMe drive has been fully configured and is ready to 
+boot independently!
+
+═══════════════════════════════════════════════════════════════════
+
+📋 WHAT WAS DONE:
+
+1. ✅ Fixed /etc/crypttab to use internal-vg/home explicitly
+2. ✅ Updated initramfs with new LUKS configuration  
+3. ✅ Reinstalled GRUB bootloader on internal NVMe
+4. ✅ Created Ubuntu EFI boot entry (Boot0001)
+5. ✅ Set boot order: Ubuntu FIRST in boot priority
+
+═══════════════════════════════════════════════════════════════════
+
+🚀 NEXT STEPS:
+
+STEP 1: REBOOT THE SYSTEM
+   $ sudo reboot
+   
+   After reboot, the system will use the internal drive's home 
+   partition instead of the external one.
+
+STEP 2: VERIFY CONFIGURATION
+   $ cd ~/Nextcloud/entwicklung/Werkzeuge/backup_to_external_m.2
+   $ ./verify_internal_config.sh
+   
+   All 7 checks should pass after reboot.
+
+STEP 3: TEST FULL INDEPENDENCE (Optional but Recommended)
+   $ sudo shutdown -h now
+   
+   Then:
+   - Physically disconnect the external USB M.2 drive
+   - Power on the system
+   - System should boot completely from internal NVMe
+   - You should be able to log in and access all your data
+
+STEP 4: RECONNECT EXTERNAL & CREATE BACKUP
+   After verifying internal drive works:
+   - Reconnect external drive
+   - Run the backup script:
+     $ sudo ./lvm_block_backup.sh
+   
+   This will create a block-level clone of internal → external
+

+
+⚠️  ABOUT THE "RESET SYSTEM" MESSAGE:
+
+The message you see BEFORE GRUB is from Lenovo BIOS, not GRUB.
+
+To clear it:
+• Press F1 during boot → Enter BIOS → Save & Exit (F10)
+  OR
+• After 1-2 clean boots, it should disappear automatically
+
+This is just a BIOS notification - your system IS bootable!
+
+═══════════════════════════════════════════════════════════════════
+
+📚 DOCUMENTATION:
+
+All changes are documented in:
+• INTERNAL_DRIVE_RECOVERY.md - Complete technical details
+• BOOT_FIX_SUMMARY.md - GRUB bootloader fixes
+• verify_internal_config.sh - Configuration verification
+
+═══════════════════════════════════════════════════════════════════
+
+🎯 CURRENT STATUS:
+
+✅ Internal drive fully configured
+✅ Boot order corrected (Ubuntu first)  
+✅ GRUB properly installed
+⏳ PENDING: Reboot to activate home partition change
+
+═══════════════════════════════════════════════════════════════════
+
+💾 BACKUP STRATEGY:
+
+Once verified, you'll have:
+
+INTERNAL NVMe (nvme0n1) = PRIMARY SYSTEM
+- Daily use
+- Main operating system
+- All your data
+
+EXTERNAL M.2 (sda) = BACKUP/EMERGENCY BOOT
+- Block-level clone of internal
+- Bootable rescue system
+- Emergency access if internal fails
