I've built my own computers for years and worked with many gigabyte motherboards but I've never seen this kind of problem before. On my new X570 Master, everything works great until i flash the main bios to a newer version. Then it fails to load windows
. However the back up bios works just fine, so it clearly not a hardware issue. I can access the main bios and change any settings but It won't load windows. It states there is no boot drive available. I thought this may have been a defective board as did gigabyte when i put in a ticket for technical support, However i got a replacement board from amazon
as i thought the first was broken and now the replacement board is doing the exact same thing. It has to be a software option somewhere, but i can't for the life of me figure out what it is and have searched everywhere. Does anyone have any ideas? I've tried re-flashing the bios, clearing the CMOS, loading optimized defaults ect. but to no avail. When i go into the bios and select the boot drive i get post code is AA, which apparently stands for reserved whatever that is. If i don't go into the bios i get post code AE and a message stating "reboot or select boot proper boot device or insert boot media in selected boot device and press a key"

Does anyone have any ideas???
