im not quite sure if i am allowed to post this as a suggestion but there exists a 9in1 windows xp disk. Uses a normal cdr and via cab file sharing will do XP PRO, Corp, Box, Home oem, box and upgrade and has media center. Has a few other tools as well and can make stand alone isos for each. I use it alot when rebuilding pcs for customers... They have a legit key i just have to call MS. Take a look on the torrent sites.
