Re: Grub2 can't find any commands [In reply to]

That's an excellent utility, I'll definitely add it to my toolbox, thanks.

I actually was able to solve my problem myself: shortly after posting I
found a post by renergy on the forums:


It looks like the magic parameters to grub2-install are --root-directory
and --boot-directory. Annoyingly, --root-directory is not listed in the
help output or man page, so I had no easy way of knowing it existed. But at
least everything works now.
