M2 drive not showing up

I have a P500 workstation from Lenovo. I installed the drive which is hidden pretty good but I did get it installed. Now the card that holds this drive is connected directly to the motherboard. I assume there is no SATA cable since it does connect directly to the motherboard? The drive will not show up even with checking for hardware changes?

What OS? Have you checked the BIOS? You may have to enable it there somewhere.

Windows 7 enterprise. I will look at the bios now. I did notice that both M2 slots are not the same. One is SATA and 1 is PCI. I am going to take a look now and also check the bios.
Look up the spec of your desktop and it says:-

Slot 1 (Near CPU)PCIe x4, gen3, “open ended”, Full Length without FLEX card; Half Length with FLEX card, FHSlot 2PCIe x16, gen3, Full Length, FHSlot 3PCIe x1, gen2, Full Length, FHSlot 4PCIe x16, gen3, Full Length, FHSlot 5PCI, Full Length, FHSlot 6 (Near Edge)PCIe x4, gen2, “open ended”, Half Length, FH

I switched slots to the other M2 slot and it still does not see the drive. I think you are correct on the specs and maybe they sent me a drive for laptops and not this P500? They sent a 512GB M2 SS drive Now seeing workstation tells me it is not a laptop but I will check with the vendor that sent the card. In P50 it finds the drive right off. That is Lenovo's laptop. It has 2 M2 slots.

To all thanks. I just saw another comment here which may be the trick. I have a call to CDW techs who think they know but I am thinking the above link for the fix may be it. I will try that today and get back. I have not forgotten this case and I still need to know why and I think the above fix may be it. I have not seen that yet.

M2 SSD is a system driver and Win 7 has no idea about M2 SSD is actually sitting on the motherboard.
It's almost certain that your issue is simply that you don't have the Windows 7 driver installed for the M2 => have you tried that yet?

Shouldn't BIOS show the drive even if Windows 7 driver is not installed?
Is that a Lenovo driver? This is a Lenovo drive.
The driver linked to above is a generic driver to add NVME support to Windows 7 => it doesn't matter what specific drive you have.
Jackie Man, why would I need to buy another card if the drive is connected to the motherboard to begin with? Not saying anything but curious as to why?
To all, I cannot thank you enough. I seem to have gone to class on this one. I found the answer and you all helped me learn and I mean you all helped. Great answers and it now works. I did enable the bios and moved the drive from slot 2 to slot 1 and it now sees the drive fine. It was not as simple as just adding the drive. This was a class. Not only finding out this desktop had so many slots but actually how to put the drive in. Lenovo was absolutely no help. We have a service for troubleshooting with them and they did not help at all. I cannot say thanks enough on this one. Now the next desktop will be a piece of cake until they change that one. Thanks again.
