Hello all,
I am currently experiencing severe boot issues in my machine. After installing a usual update and rebooting as prompted, the system could not boot anymore. Now the only way to access Kubuntu 22.04 is after having loaded GRUB, then the recovery options and then boot, which boots without any graphic driver support but at least I can write this message. Any direct way of booting gets either hung in black, blinking cursor, "GRUB failed boot detection" or hung after "finished terminate plymouth boot screen". I have tried everything, even reinstalling GRUB several times but to no avail. The popular Rescue Disk utility refuses to work because it says it is in a legacy BIOS session but I cannot change this because the machine is from 2013 hence not UEFI capable. Here is the pastebin from the utility for context:

Suggested repair: __________________________________________________ ____________
The default repair of the Boot-Repair utility would reinstall the grub-efi of
sda3,
using the following options: sda2/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file
Blockers in case of suggested repair: __________________________________________
The current session is in BIOS-compatibility mode. Please disable BIOS-compatibility/CSM/Legacy mode in your UEFI firmware, and use this software from a live-CD (or live-USB) that is compatible with UEFI booting mode. For example, use a live-USB of Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd), after making sure your BIOS is set up to boot USB in EFI mode. This will enable this feature.
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the The OS now in use - Ubuntu 22.04.3 LTS entry (sda2/efi/****/grub****.efi (**** will be updated in the final message) file) !
The boot of your PC is in BIOS-compatibility/CSM/Legacy mode. You may want to retry after changing it to UEFI mode.
