This is a new PC build. A Z390 Aorus Ultra. I am only using a 970 Evo Plus NVMe M.2. It is in the bottom slot (which is the only slot it fits in so I assume that's the right spot). When I go into the BIOS under M.2 it shows all 3 slots as N/A. My processor, ram, graphics card, sound card, and fans are all showing up fine. If I try to install Win 10 from the usb it can't find any drives to install on. Any help would be great. Thanks.
