Yea. On one computer I have vista home (which came with the computer).
And lets see. I was trying to dual boot my other one to have both vista and xp. with vista already on there. but all the xp disks i had wouldnt boot for some reason. so i just restored it back to xp. Then tried out 2008 server (suck) and now back to xp.
in the grand scheme of things im hoping to install xp to my external hdd so i can boot xp from any computer.
