New build completed & powered up successfully into MSI Click BIOS 5 screen. Am stuck at bios screen because the PM951 NVME ssd is not even showing up as an option for me to select it as the boot drive. Unable to figure out how to instal Windows 10.

I am a complete newbie where UEFI bios and am unable to figure out the UEFI settings to get NVMe SSD recognized bios.

My build as follows:
MB: MSI Z170A XPOWER TITANIUM (MS7968)
CPU: i7-6700K
Mem: 32GB G.SKILL TridentZ DDR4-3200mhz
Graphics Adapter: None (using i7-6700k on board graphics) initially.
CPU cooler: CORSAIR H75 liquid cooler
PSU: Seasonic Prime Titanium 750w
SSD: Samsung PM951 512GB NVME
(.. currently no other HDD is installed..)

Any advice/instructions on to set Z170A mobo:s UEFI bios to recognize PM951 NVMe m.2 ssd desperately requested.

Many thanks
Ian

Finally figured it out ......

All I know is, NVME needs a driver. That's how an NVME SSD works.

If you want to boot from it. But first the BIOS has to support it (booting from an NVME SSD).

If it doesn't, then even if you buy an NVME SSD, you wont be able to boot from it

Just read a post in here on how to add the drivers. It'll probably work on any system.

Seems my bios settings based on my own rudimentary understanding of NVMe and the UEFI bios was actually correct after all and with regard to the driver, I just was not at that stage yet... was only successfully at BIOS screen when rig booted up but it was not recognizing the PM951. (..besides, Windows 10 has it's functional native NVMe driver which should be adequate until the latest Samsung 2.0 NVMe driver could be installed...) I had already tried all conceivable other bios setting permutations when the PM951 was not recognized... BUT most frustratingly, it was no joy at all..!#*!!

Finally, gave up, crawled into bed @7am after the unsuccessful overnight marathon session and I returned to the workbench 4 hrs later. At that point, I recalled I had been very careful inserting/securing the PM951 into the mobo M.2 slot since I'd never even seen a M.2 ssd for real before now.

Guess what..?? Probably I had been TOO careful 1st time around ... cause I removed the M.2 & reinserted it but this time I made a point to FIRMLY PUSH the gumstick ssd (..somewhat horizontally..) into the M.2 slot WHILE holding it down to secure it in place with the screw. .. the idea being that all those gold fingers on the PM951 needed GOOD contact with the respective pins in the mobo M.2 slot.

Tongue in cheek, I booted up again... it was really Christmas this time around..!!
Hopefully this will also help some other frustrated M.2 newbie out there...

Admin, kindly mark this "SOLVED". Thanks for bandwidth ..

Hi Paul:
SATA ... AHCI ... NVMe .... how these generally (and each individually) play with MBR ... UEFI ... and then add to the melee, throwing in PCIe Gen 2 vs Gen 3, AND of course the different permutations the different manufacturers' Z170 mobos implement the Skylake channels...etc, etc... THEN the still confusing situation when it comes to Win7 vs Win10 and native driver availability .... USB vs SATA channel for install of Windows ......

I apologise, but my rather disconnected rambling above highlights my rudimentary awareness of how each issue relates to another and hence the differing hardware/software conditions. Thanks for getting back but quite honestly, I can't say I understand what you are communicating. As I stated, I'm very much a newbie when it comes to UEFI and the M.2 NGFF gumstick ssd .. but I'm getting totally confused ...all over again .....
ie how do hardware drivers come into play at the BIOS level so that it will affect POST ... can one modify/supplement the ability to recognize specific hardware during POST .... if so, how ...
