My son's laptop will not boot with message "No Boot Device Found. Press any key ...." He has Win 7 64-bit, with a HDD, and a DVD optical drive.
I checked BIOS for boot order and internal HDD is first, optical second.
Ran diagnostics and it said HDD was not installed (see attached) and that CDROM Drive 0 - Self test: OPU test failed with error code 2000-0147 (see other attach.).
On reboot and pressing F12, it says Legacy and shows the CDROM, but no HDD.
