I currently have win 7 booting vista if I want. I'd like to install XP in the vista partition and just boot 7 and XP. Can I install XP (over writing vista) and have 7 show up in the boot time menu? Thanx, Bob

Installing XP will make a MBR that points only to XP, afterwards you will need to boot off of the win7 install disc or recovery disc and repair startup problems. Not sure of the exact steps...Hello!
