Is the "GRUB" message before or after the usual menu?

If you can get the GRUB menu, but can't proceed booting as normal, you
can probably repair GRUB at this stage.  At the menu, hit the hot key
(c) to get a GRUB command line interface, then go through the following
three commands in the grub shell:

grub> root (hd0,0)
grub> setup (hd0)
grub> exit

Try booting.

NB: "grub>" being the shell prompt, not something you type.

If it doesn't get as far as the menu, you can try the rescue disc, and
do the same thing, but start the GRUB shell, first, yourself.  Simply
type grub at a command prompt, then those three commands, when you get
the grub shell.

The GRUB manual <http://www.gnu.org/software/grub/manual/> can be read
on-line.
