So GRUB has a different way of referencing drives and partitions. It uses a tuple like (hd0,1) instead of /dev/sda1 etc.

This makes it a bit difficult if you try to boot an external disk since the order might be different. But usually the main drive is hd0.

What you can do instead is to reference the partition using a UUID in the grub config:

search --no-floppy --fs-uuid --set=root <UUID>
