Guys, Been trying for 2 days to remove Win 7 and reinstall XP. No windows.old file found because I formatted C drive before installing Win7 (Big Mistake!!). After setting up bios to run from my XP installation CD, it won't boot up but continue to start Win7. Any help would be much appreciated. 1. Don't need dual boot. 2. XP drivers no problem as I have the support CD with me.
