I would suggest you make a grub booting floppy disk
then you can escape to command mode once the disk
loades and install grub with

root (hd0,0,a)   # or wherever it is
setup (hd0       # again wherever it is

assuming you have already placed the grub bootfiles on
your hard drive and configured menu.lst you should be
all set. I have only encountered one computer this
method failed.

you could alternatively flip the kernel tunable that
allows raw writes to the boot sectors of the disks. I
don't recall what it is but I think the grub docs talk
about it in the man or info pages.

I'm supprised XP messed it up, 2000 seemed to respect
existing bootloaders...
