Thanks for the reply, so the bad thing was my old HTPC rig wasn't up for booting to a DVD. So I tried various methods (Flash Drive, Diff. Programs, Lower ISO Burning Speed) with all the same results. I decided to just pop the disk in Windows XP and install. It went good, I installed it on my secondary HDD and now its running dual boot. Hopefully it remains this way! Thanks for the help!
PS. Windows 7 looks amazing!
