I have just built a new computer. And for some reason after installing Win XP Pro I can't boot to windows without having the disk in the cd rom drive. Everthing is set to boot from ide 0 but it insits of booting from the CD. I put the cd in the drive and I don't press anything when it says press any key to boot from cd and then it boots to the OS. If disk is not in cd drive then it keeps looking for the disk.
