That is the way you install grub for old MSDOS partitions.

To install grub with GPT and use EFI, it needs different
arguments. Something like:

grub2-install --target x86_64-efi --removable --boot-directory=/mnt/boot --efi-directory=/mnt

Though that's from my notes for making a bootable USB stick, so probably
not all of those are needed for a hard disk. Read about the options in
the grub2 info docs.
