Alienware 13, No bootable devices on boot

Hi,

Saturday night, after updating and launching a game, my computer (Alienware 13) froze.  I restarted only to get the dreaded 'no bootable devices' screen. Figuring it was a problem with the hard drive I check the BIOS, but the hard drive was shown as being detected. So I ran the diagnostics, and again the hard drive was shown as detected and after a full scan, nothing was found to be wrong.  I then went back to BIOS, reset settings to default, and double checked the boot order and nothing seemed to be out of order. (Current boot order is 1. Windows Boot Manager 2. Onboard NIC (IPV4) 3. Onboard NIC (IPV6).) After trying to fix it through the BIOS, I tried a power drain, and unplugging and reconnecting the HDD from the motherboard, both to no avail. At this point I'm running out of ideas and figured I should take to the forums. Thanks for any help in advance.
