What should I do exactly?
If anyone is interested, I can provide the pastebin link which boot-repair has generated
Below the final file part
Thanks!
=================== Repair blockers
GPT detected. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again.
Alternatively, you can retry after activating the [Separate /boot/efi partition:] option.
=================== Advice displayed in case of recommended repair
EFI detected. You may want to retry after activating the [Separate /boot/efi partition:] option.
Do you want to continue?
=================== Final advice in case of recommended repair
Please do not forget to make your BIOS boot on sda (1000GB) disk!
=================== Default settings
Recommended-Repair
This setting would purge (in order to fix packages) and reinstall the grub2 of sda2 into the MBRs of all disks (except USB without OS).
Grub-efi would not be selected by default because: no-win-efi
Additional repair would be performed: unhide-bootmenu-10s fix-windows-boot
=================== Settings chosen by the user
Boot-Info
This setting will not act on the MBR.
No change has been performed on your computer. See you soon!
