Hi Btank,

I've encountered this as well, when I disabled something in BIOS regarding Boot opions. It is a pain in the ass to get correcting. Even after getting back into BIOS, I couldn't select a hard drive to boot up into.

To get into BIOS, I unplugged the device and pulled the battery for ~30 mins. After putting the battery back in, I was able to boot straight into BIOS, without key pressing, due to the lack of a bootable drive. I had a USB boot stick, choose this, and was able to get back into a command prompt. I don't remember if I did anything here, but on reboot, was able to see my drive again and get back into Windows.

i think you can unplug HDD or bootable device, BIOS will re-recognizing, if you still have problem, i think you sent to service center to reflash BIOS.
