Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to fix packages) and reinstall the grub-efi-amd64-signed of
sda5,
using the following options: sda1/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.
Confirmation request before suggested repair: __________________________________
The boot of your PC is in BIOS-compatibility/CSM/Legacy mode. You may want to retry after changing it to EFI mode.
Alternatively, you may want to retry after deactivating the [Separate /usr partition:] option.
Are you sure you want to continue anyway?
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on sda1/efi/****/shim****.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.
Je ne sais pas si ça peut vous aider.
