New motherboard not detecting boot device, but manual selection will still boot.

I just installed a new motherboard, I needed some more RAM slots. I picked up an ASRock FM2A88X Pro3+. Everything's fine with the board as far as I know. I know some people are having issues with the product being defective, but this one works just fine.

Except for one small bug I think is software related. It was working just fine for a few boots, but now the boot order seems to be changing on me for no apparent reason. Or at least, it's not automatically finding my copy of Windows 7.

I boot the PC, I get a black screen with 'no boot device detected, reboot or press any key to try again'. I thought that the HDD died or something, but the HDD still appears in the BIOS when I look at boot devices.

If I go into the bios and change the boot order to put the HDD in the first slot to boot from, it starts up just fine. If I hit the key to open the boot menu and select the drive, it boots up just fine. It just wont automaticly boot from disk when I hit power.

The only BIOS settings I changed were to overclock my ram from 1333 to 1600 and that went over just fine (8 hours in MemTest produced no errors), as it should with HyperX DIMS. All other settings are 100% stock.

the "not automatically finding my copy of Windows 7" part made it unclear.

welp... this may be your first encounter with having to reinstall Windows when changing motherboards.

No, it's not a blank harddrive. (I mean, I said it boots if I manually tell it to. So um, it couldn't be a blank drive.) It's the drive that was used with my previous MB. I only changed one part out, everything else is from the old rig. I've never had a problem with just plugging in an old HDD to a new computer.

The OS install is usually tied to the motherboard. I dont mean the product key, which Windows 10 does, but the install itself is configured to the original motherboard before the swap. This means you need to do a clean install of the OS.

Backup what you can, if you can first, obviously.
