The following commands work for me to fix grub until I boot in XP again. Could
you confirm that they work for you?

1) Boot Knoppix, rescuecd or another live cd.
2) Mount Ubuntu partition somewhere
3) chroot /mnt/ubuntupartition/ bash
4) grub-install --recheck in the place you wish to install boot (take care of
not overwriting something else)
5) update-grub
6) exit
7) umount ubuntu partition
8) reboot and eject live cd.
