Suggested repair:
The default repair of the Boot-Repair utility
would reinstall the grub-efi-amd64-signed of
sda1,
using the following options:
sdb1/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 The OS now in use - Ubuntu 20.04.2
LTS CurrentSession entry (sdb1/efi
/****/shim****.efi (**** will be updated in the
final message) file) !
