Please Help!! Lost CD/DVD Drive after Vista Reboot

I recently upgraded my hard drive, and reinstalled Vista HP. After installation I went to upload all my files I had backed up to disks. When I insert a disk I feel it spooling up, but it never brings up any prompt or anything. I looked in my computer but the dvd drive does not appear. It shows all other drives. I have tried disk management, registry editor, and even bios. None did me any good. It’s as if Windows just can’t see it. Please Help me!!!
