It seems the XP CD is not recognised as a bootable disk by the BIOS or CD Drive. Therefore, during the boot process, it by passes the CDROM boot option and checks for any OS on your hard drive.
2 things you can test:
1. Pop another bootable disk in the PC. if it works, then its your XP CD that is faulty.
2. Take the XP CD and boot it up from another PC/laptop. If it works, then it could be your CD Drive or BIOS.
