yammata, I had a look around I reckon this would be a good bet to get rid of the entry (you added) that's causing the trouble: http://forums.kustompcs.co.uk/showpost.p...ostcount=5

So you'll need a hard drive with XP installed, connect it to your current rig, boot into it, and use the regedit in there to load the Registry on the drive with the unbootable XP.. remove the entry and you're done.
