=================== Recommended repair
The default repair of the Boot-Repair utility will reinstall the grub2 of sdb8 into the MBR of sdb.
The boot flag will be placed on sdb2.
Additional repair will be performed: unhide-bootmenu-10s


parted /dev/sdb set 2 boot on


Information: You may need to update /etc/fstab.
