|If you have a Bootable disk then I suggest you try booting directly to it from a shutdown. If the disk is recognized there then the problem lies with Windows. If the disk is not recognized then you have a hardware problem. Possibly the DATA cable. I assume if the tray opens you have power to the drive.|
NOTE: The boot order must show CD before the hard drive in order for this to work. Watch the screens at start up for prompts.
