(debug) reinstall grub2 place-in-MBR no-BIOS_boot (mapper/ubuntu--vg-root)
=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to fix packages enable-raid enable-lvm) and reinstall the grub2 of mapper/ubuntu--vg-root into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s
=================== Blockers in case of suggested repair
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.
=================== Advice in case of suggested repair
Warning: continuing without internet would leave your system unbootable. Please connect internet.
The boot of your PC is in EFI mode, but no EFI partition was detected. You may want to retry after creating a EFI partition (FAT32, 100MB~250MB, start of the disk, boot flag).
Do you want to continue?
=================== User settings
The settings chosen by the user will not act on the boot.
