Question M.2 Detection Problem

[Unrealfate21]

I recently built a new PC and I have had some issues with my M.2.
The driver is not being detected in my bios, however it is being detected in Disk Management. In my old PC the drive was working perfectly.

List specs of your system.

Probably need to assign drive letter to the drive.
