SUMMARY 


STEPS TO REPR.ODUCE
1. Install KDE neon 22.04 on Lenovo IdeaCentre B750 onto 256GB SSD using downloaded .iso installer on USB Flash using GPT/EFI partitioning. Use Neon 22.04 daily for months, and customize desktop and panel.
2. Backup SSD EFI and root partitions to external 2GB USB backup hard drive using gparted partition copy and paste, and generate new UUIDs for for each new backup partition with gnome-disk-utility or gparted.  Verify that PC boots 22.04 LTS Neon from external USB drive.
3. Check for updates with Discover, and wait till 24.04 LTS Upgrade appears in systray.
4. While backup drive is still attached, execute 24.04 LTS upgrade by clicking on Upgrade icon in systray. Follow prompts to complete the upgrade.external USB backup drive (Note that OS prober was invoked and modified the backup drive's boot configuration, by watching upgrade details window.  Upon completion, restart the PC.

OBSERVED RESULT:
The PC will not boot Neon from either the SSD drive at 24.04 or from the external USB backup drive at 22.04.  After using BIOS boot manager to select which drive to boot from BIOS boot manager, observe that the PC then goes to the BIOS Setup screen after about 15 seconds attempting to boot without displaying any text logging of neon boot attempt on PC screen.  After inserting my original 22.04 live .iso installer USB flash drive, boot from live USB flash and the mount SSD and external 2TB Hard drive partitions and observe that they are intact, but will not boot.

This upgrade was a complete disaster for me that will require multiple days of my time to reconstitute a new working Neon system, with all the apps and panel icons that I have lost.  I suggest you withdraw the 22.04 upgrade from the Discover updater until you can test and resolve this issue, which has apparently been experienced by others.  Fix it before it breaks too many other people's systems!!!

EXPECTED RESULT:
The PC should have booted 24.04 LTS from the SSD that was upgraded, and also should have been been able to boot from external 2GB USB hard drive, which should not have been modified by the upgrade process.  (I could have protected the 2TB external USB hard drive images by unplugging the USB hard drive's USB cable from the PC's USB port before attempting the 24.04 upgrade, but who knew the upgrade would break it?)

If you can let me know what upgrade log files you would like me to upload, I can attempt to retrieve them from the SSD drive, but please do so quickly, because I need to do a clean install of 24.04) on the SSD. Also if it is possible to recover my Plasma panel customizations from my backup, and reinstall them on 24.04 Plasma, please let me know how.
