I built a new pc yesterday and wasn't having any problems. Today I decided to go and update the bios on my motherboard, and now I boot to the bios every time. Now the reason it is doing this is because it has no drive to boot to, which is kind of weird since it was just working. It's supposed to boot off of an m.2 drive, so I don't know how the connection could have gotten loose. However my other two hdd don't show up either. Flashing to a beta bios as well as the original didn't seem to do anything. All three of the drives can be seen in other menus within the bios, I just can't seem to select any of them as a boot device. Any help is greatly appreciated!

If I put in my windows iso usb stick I can boot to it just fine. Booting to things doesn't appear to be a problem I just don't have my hdds as an option.
