Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of
sdb5,
using the following options: sdb1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the L'OS actuellement utilisé - Ubuntu 20.04.1 LTS CurrentSession entry (sdb1/efi/****/shim****.efi (**** will be updated in the final message) file) !
Je pense que ce n'est pas la cause de ton problème de plantage mais ton installation de Xubuntu n'est pas conventionnelle. En effet, on peut voir qu'il s'agit d'une installation en mode EFI mais la table de partitionnement qui convient à une installation en mode EFI, c'est le type GPT alors que dans ton cas, c'est le type MSDOS qui est utilisé pour sdb comme on peut voir dans cet extrait :
