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
sda4,
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 SteamOS Holo (rolling) entry (sda1/efi/****/shim****.efi (**** will be updated in the final message) file) !
