=================== 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 sda2, using the following options:        sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file


=================== Blockers in case of suggested repair
The current session is in Legacy mode. Please reboot the computer, and use this software in an EFI session. To povolí tuto funkci. For example, use a live-USB of Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd), after making sure your BIOS is set up to boot USB in EFI mode.


=================== Advice in case of suggested repair
Varování: pokud budete pokračovat bez internetu, nebude možné spustit váš systém. Prosím připojte se k internetu.
The boot of your PC is in Legacy mode. You may want to retry after changing it to EFI mode.
Alternatively, you may want to retry after deactivating the [Osamostatnit oddíl /boot/efi:] option.
Chcete pokračovat?


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on sda1/efi/.../grub*.efi file!

The boot of your PC is in Legacy mode. You may want to retry after changing it to EFI mode.


=================== User settings
The settings chosen by the user will not act on the boot.
