I found the problem to this was the wrong type of m.2 drive. from what i have found out the amd boards dont like the slower m.2 drives. mine was the sata m.2 with 2 slits.  Thanks for all the suggestions
I have bought a second hand r10 as pretty much the motherboard case and psu. I've bought a Ryzen 7 3800XT to go in it. I've put it all together using the contents of my old Aurora R8. On boot up, everything looks fine until it cannot locate any of my HDD. I have an M.2 that I tried in both the slot on the motherboard and a separate PCI card. Also a Seagate 1TB 3.5" drive. Both have Windows 10 on and worked fine in my Aurora R8. What am I doing wrong?
