M.2 key M slot, NVME card not recognised by win10

I instaled a western digital black 1To NVMe SSD in the M.2 key M slot, not recognised by windows, Only the drive C with the system is detected. Is this card suported? Is the slot defective ?or something to modify in the bios or additional program to install ? Could you list some precise références of cards that will work for sure on the alpha.
Many thanks for some help Attachments 20190223_150827.jpg (2.82 MiB) Viewed 2552 times
