Hi, again, jacksbutler.

Looks like your setup is not like mine at all. Sorry.
Maybe dinosoep can steer you better.

FWIW, I don't have a grub.conf, but I do note that my /boot/grub
files are root:root. In which case if I wanted to edit grub.conf
I would need to start out with

sudo leafpad /boot/grub/grub.conf

so I could save my edits.
