Question Help needed - ASUS Bios suddenly won't recognize any HDD's for boot sequence

My 15 year old son was playing around with his computer in the Bios utility and now his computer will not boot to anything but the Bios screen. I look at the display and it shows the hard drives (center of picture) but does not show them on the right side as a Boot Priority. I checked the connections in the unit and it seems fine.

It's like the HDD's don't exist any more. If I plug in a USB Windows boot disk that shows up, I have no idea what happened. Any tips?

I would post the picture of his bios screen on here but I can't seem to figure out how to put a picture on this post.

Any help would be very appreciated!
