[SOLVED] Can't get Windows to detect my new M.2 drive

Hi all,

I just purchased a Samsung 970 EVO Plus M.2 SSD which I installed in my existing build (MSI X99A Tomahawk with I7-6800K CPU) to act as an extra secondary drive but I cannot get either Windows or the BIOS to detect it.

I have found some threads similar to the issue I'm having but I am still at a loss.
Am I understanding correctly that the M.2 SSD cannot be a secondary drive and can only be the boot drive? If not, what am I doing wrong?

Thanks for your help

UPDATE: It now works. The drive appeared in the Disk Management utility and I could initialize it. I did a couple things so I'm not sure which one fixed the issue but I assume it was updating the BIOS to a more recent version even though, if I enter the BIOS, the drive is still nowhere to be found.

HOWEVER, it is running very slowly. I installed the Samsung NVMe driver; no improvement.
Here are the results of running winsat on the drive.

Code:

I've read some stuff about PCI lanes but the only other PCIe peripheral connected is a GTX 1080 ti


EDIT: I guess as far as the title of the thread is concerned, this issue is resolved. Takeaway: update your BIOS

Thanks for your reply.

I tried that. I downloaded the driver but it won't install. Says "Samsung NVMe device not connected. Please connect the device" and exits. (I double checked that it's correctly installed).

Anybody else got an idea?
I read somewhere else something about it working (for my MoBo at least) only with UEFI and not BIOS, but that's beyond my understanding

Here is what the specs for my motherboard say:
• 1 x M.2 slot (Key M)*
Supports up to PCIe 3.0 x4 and SATA 6Gb/s
Supports 2242/ 2260/ 2280/ 22110 storage devices
The specs for the drive say:

INTERFACE

PCIe Gen 3.0 x4, NVMe 1.3
Could there be something there? The drive is NVMe but the board expects SATA?
