You probably have a hardware or a CD problem.Are you sure, that your CD drive and your burned CD are ok? Please give more details about your system (graphic card, soundcard, IDE and USB devices etc). well my cdrom drive is a LiteOn DVD-+RW. I have no reason to belive the CD's I am making are bad... How else can I test? I installed Windows XP with a CD I've tried in this system and it didnt work (although the one it worked on didnt have SATA). I have an XFX GeForce 7800GT, onboard sound (Abit KN8 SLI), I have my DVD-+RW and a 180gb EIDE hard drive (the hard drive is unplugged to avoid conflicts), and a USB mouse&keyboard.
