Thanks much. I would hazzard a guess here and say that it has to be BIOS related. (apart from the last option) * Either your BIOS doesn't support booting from CDROM * You never saved the BIOS settings when you set the CDROM to be the first device to search. * or, your CDROM image does not contain a bootable image...
