Oh, another thought: when it gets to the grub boot, edit the kernel line
to add rdshell at the end; hopefully, if it fails, it will give you the
grub shell, and you can find out where the actual root drive *is*, which
is, I think, what it's looking for and not finding in the grub line that
tells it where / is.
