[SOLVED] Asus X390-P storage problem

[Deezadams]

Asus z390-p can’t find a hard drive and can’t see the way to turn off csm. It doesn’t see my hard drive and I know it works because I tested it

What BIOS version are you working with on your motherboard? Might want to parse some images of what you see in BIOS. You should be able to disable CSM and then set the OS to other.
