This is my first time building a pc. I'm trying to make my HP EX920 my boot drive but my motherboard doesn't detect it. When I try to install Windows 10, no drives are listed at all. I read that I have to enable M.2 in my BIOS, but I don't seem to know how to do that. Anyone have a solution to this? I have been googling a ton of solutions and none of them work.
