=================== Default settings of Boot Repair
The default repair of the Boot-Repair utility would purge (in order to sign-grub enable-raid enable-lvm) and reinstall the grub-efi-amd64-signed of mapper/ubuntu--vg-root, using the following options:        sdb1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file rename-ms-efi


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on sda (1000GB) disk!


=================== User settings
The settings chosen by the user will purge (in order to sign-grub enable-raid enable-lvm) and reinstall the grub-efi-amd64-signed of mapper/ubuntu--vg-root, using the following options:        sdb1/boot/efi,
Additional repair will be performed: unhide-bootmenu-10s    use-standard-efi-file rename-ms-efi
