Western Digital M.2 SSD shows in BIOS, not in disk management or windows file explorer

[nevyn04]

Hi,

I recently built a gaming PC. Specs listed below.

MSI Z270 SLI Plus
I5-7600k cpu
16 GB DDR4
ASUS GTX 1070 Ti turbo
750w power supply
Hitachi 2TB HDD
Western Digital 512GB M.2 SSD
Windows 10 Home

I have tried the SSD in both M.2 slots available.
I have updated the bios.
I have tried to switch from "Raid/optane" mode to "AHCI", setting doesnt stay.
Drive shows in BIOS as PCIe Remapping.
I have verified that it is enabled.

I've run out of things to try and majority of forums either lead to dead ends or are showing in disk management, and thus fixed that way. My drive only shows in BIOS.

Any help you can give would be appreciated. Im currently running windows on the 2TB drive, but want to place it on the SSD if i can get it to work.

Thanks in advance.

Which drive is that because WD makes NVME and sata m.2 drives.
