In order to use the installation CD your BIOS (set-up) must be set to use the CD/DVD drive as the first boot item. Then you install the cd in the drive and reboot.....when prompted " hit any key to boot to CD" hit the enter key and allow it to enter set-up and start loading files. at anytime the computer reboots and the hit anykey....prompt shows back...ignor it and let the computer run.
