I was running Kubuntu 25 without any problems. While watching a sport live stream there was a power cut, the machine doesn’t have a UPS.
When power was restored, the machine would not start without going to a safe graphics mode.
I downloaded the Boot Repair Disk tool, put it on a USB and booted to it. For several days I have tried to get it to generate a GRUB menu that would work. Once and only once I got a boot sequence that took me to a completely operational Kubuntu. I stupidly altered the GRUB configuration to try and make the boot option the default, only to completely lose that GRUB option.
When I boot in to Boot Repair Disk, the graphics are fine. All 3 screens are correctly identified and I am able to alter the display settings.
I have spent many days looking at this and have made no headway. It’s outside of what I know and I’m guessing. Now I’m hoping for something more intelligent than guesswork 🙂
This is the URL to a pastebin of the current boot https://paste.ubuntu.com/p/hgm5ymnnBg/. What else do you need to analyse the problem ?
The desired result is taht I boot in to Ubuntu 25.04 on sda3
Cheers
It turns out that pastebin isn’t what I thought it’d be. Below is the output from the Boot Repair Disk boot analysis.

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to enable-lvm) and reinstall the grub-efi of
mapper/ubuntu--vg-root,
using the following options: sda1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file restore-efi-backups
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the Ubuntu 20.04.3 LTS entry (sda1/efi/****/grub****.efi (**** will be updated in the final message) file) !
