I'm trying to install W10 and no matter what I do it cannot detect my M.2 drive. It's the only drive hooked up to the motherboard. I tried moving my GPU to the second PCIe slot in case the M.2 slot shared resources with the first PCIe slot but that didn't fix the issue. Anyone have any ideas? Is there a setting in the UEFI?

| Is your "WD Blue 3d NAND 500GB M.2 Drive" (SATA) installed on the second M.2? So not the one labeled "Hyper M.2" which is for PCIe M.2 |

Okay, so I think this is exactly the problem, only my board doesn't have that second M.2 slot! You can see where it's supposed to be, but it isn't there. When I look at the description on Newegg (and on the ASRock site) for the B550 Phantom Gaming 4/ac it says there's two, but when I look on the box I received, it says there is only one! (Hyper M.2) How is that even possible? Did they manufacture it with Hyper only at first and I have an old model or something? In any case, it is advertised with both slots on the Newegg purchase so I'm going to contact them right away. You are awesome Reset! Do you have any idea why mine wouldn't have both slots?

1 - your MB has only one Hyper M.2 slot, not 2. 2 - you have incompatible disk (M.2 SATA instead of M.2 NVMe) ------------- AB350 Gaming-ITX/ac 10.31 BIOS| Ryzen 5 5600| G.Skill Flare X 2x8GB @ 3466 14-14-14-28| Zotac RTX 5060 SOLO| Kingston KC3000 1 TB M.2| SilentiumPC Supremo M2 Gold 550W V2| Plywood case 24x22x21 cm |

Yes, that's what I was saying in my last post. It makes no sense because on the Newegg description and the ASRock description of the B550 Phantom Gaming 4/ac it says there are two, one SATA and one PCIe. As a resolution, I contacted Newegg and they are allowing me to return the M.2 drive which I will be replacing with a PCIe drive compatible with my Hyper M.2 slot. I imagine this will solve the issue! |

On the ASRock site i can see clearly: 1 Hyper M.2. If you see 2 then you look on the other board. ------------- AB350 Gaming-ITX/ac 10.31 BIOS| Ryzen 5 5600| G.Skill Flare X 2x8GB @ 3466 14-14-14-28| Zotac RTX 5060 SOLO| Kingston KC3000 1 TB M.2| SilentiumPC Supremo M2 Gold 550W V2| Plywood case 24x22x21 cm |
