Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi of
sda2,
using the following options: sda1/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 Ubuntu 20.04.6 LTS entry (sda1/efi/****/grub****.efi (**** will be updated in the final message) file) !
