Question about HP Media Center m7250n (ED842AA) PC Desktop
Disconnect the "data" and "power" cables from the disk-drive.
Boot from the Recovery DVD, just to prove that your computer can boot. Of course, you may get an error-message, when no disk-drive is detected, but you will have proved that your computer can boot properly.
Connect a different disk-drive, and boot again from the Recovery DVD, to confirm that it will boot, when some "other" disk-drive is detected.
