I have a dual boot system XP and KK9.10. The KK9.10 is a fresh install and after booting back into the XP system and trying to restart, it now hangs and I can't get either OS to load with a 'GRUB loading' message.

When I run the the KK9.10 cd, it detects the drive, but I'm unsure which file(s) to edit to get the grub2 menu again to list which OS I boot into.
