M.2 drives not being recognized in bios or Windows

[Lawrenjj]

I've tried an NVME and SATA m.2 SSD. I've upgraded bios and installed drivers but neither are recognized in bios or system. I've tried a Samsung 960 Evo and Crucial mx500. Both are 256GB. Any ideas for anything else I can do to get one pf these working or is the port just shot on the MB?

Hi,

According to the guide you can use dual storage (e.g. 1TB HDD and 256GB SSD) but appart from applying a BIOS update i don't really have any other ideas.

So I got it working finally and the solution makes no sense at all. I had to try to install a new copy of Windows and erase all partitions from the 1tb HDD. After I rebooted into the installer the SSD showed up. Both the SATA m.2 and the NVME work fine without issue now.

Too late now, but I wonder if just disconnecting the SATA cable from that HDD would have achieved the same result ?

Probably but I was going to format it anyway.

Hi,

Well, if you did add the SSD, did you also check in Disk management for any unformated partitions ?

If its not detected in BIOS its one thing but if it is but not in Windows, sometimes you just need to check any drives in disk management and make sure that the device is formated and you have an active partition.
