Hi all, my brother bought a computer from someone and it won't recognize the nvme m.2 or older ssd as a boot device. Using bootable thumb drive i have installed the OS on both. The motherboard is an Asus z270-p, ssd is a pny, and nvme is a crucial m.2. If I put a ssd in from his previous computer it recognizes and boots from. Kind of lost at this point but I wouldn't doubt it's something simple I've missed. Thanks in advance!
