Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
mapper/vgubuntu-root,
using the following options: sda2/boot, sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file
Confirmation request before suggested repair: __________________________________
You may want to retry after mounting your encrypted partitions so that the tool can verify their contents. (https://help.ubuntu.com/community/EncryptedPrivateDirectory)
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 the L'OS actuellement utilisé - Ubuntu 20.04.2 LTS CurrentSession entry (sda1/efi/****/shim****.efi (**** will be updated in the final message) file) !
Il s'agit d'une installation avec chiffrement. Moi je ne pratique pas ça. Je passe.
