actually from the get go there really was no need to reinstall windows.... of course its always a good place to start... all you probably had to do was login as the local admin (every computer has one) and then remove it from the school domain... at least thats my experience with it...
could be possible the drive just doesnt like to boot stuff from it?
i had that problem when messing with xboxhdm.... the IDE cd drive i was using was set to master, set appropriately in the bios, etc. it just wouldnt boot...
however i booted windows with it installed, and it worked no problem... weird huh? i'd definitely try to get another good cd drive that you know boots cd's and do it that way
