Most likely a chroot issue.  I've done that sort of thing before, but I
don't recall the steps.  It wasn't too hard to work out, and since I
don't regularly bugger up a PC, I haven't remembered it.

I've done something similar, as well.

Yes, that's not going to work by default.  I think it's only going to
work if you have some other bootloader, that you can point to where
you've installed GRUB.

Well, you can interrupt booting, while the GRUB menu is up, by pressing
some hotkeys.  I seem to recall that the bootscreen prompts you, but I
can't see it now, and I'm not going to reboot in the middle of writing
an e-mail to see.

You can also type in "grub" into the command line on a running system
and do most things in that environment.  I think you want to read the
grub info file, the man file is rather spare.

e.g. info grub

There's an on-line version somewhere, which is a lot easier to browse
through than "info" files are.
