BIOS Cannot Detect Boot Drive

This is an update post from an earlier issue I had with my new motherboard -- quick summary, I bought the Mini-DTX board from ASUS, kept getting Q-Code 02, and I just recently (about an hour ago) got to the BIOS after flashing a new version. Now I can't boot because the BIOS doesn't detect either of my boot drives; both are plugged in, with both power and SATA connections. I need help figuring this out.

 

My specs:
- Crosshair VIII Impact
- ZOTAC 1070 Ti Mini
- Ryzen 7 3700X
- 16 (2×8) GB 3200 MHz G.Skill RAM
- 240 GB SSD (boot drive) + 3TB HDD (bulk storage)
- Seasonic Prime PX1000

Jayztwocents was recently building a computer with that exact board and had the same 02 no post error I believe he deduced it was an issue with the board and his 10 series 1080ti he was trying to use with it, which may have been patched in the recent bios update as for the boot drives, is it showing the drives at all in bios or not at all?

It's not showing the drives at all. I think I'll try some of Tristerin's recommendations and test one at a time to see if any of that works.
