Need to set everything up to UEFI otherwise you won't see a thing or boot.  

Have gone into the bios and enabled UEFI boot - have also manually booted from the UEFI:USB option and still no joy.

Have also tried disabling and enabling Launch CSM

Every UEFI option has been enabled and still nothing!
 
Any other ideas?

Thanks Scarlet!
Will check the bios settings when I get home from the office!
 
Currently they are set like this:
 

Should I be seeing the drive in the PCI-Express area top right?  Or is that just for GFX cards?  Should CSM be enabled or disabled?  Does this look ok?

Ok.  Im getting nowhere fast with this! lol
 
I have gone into the BIOS and enabled the M.2 Socket3 on the Advanced Tab
 
On the Boot Tab i have changed the Boot mode select to UEFI
I have selected for Boot option 1: USB HD UEFI
 
Under CSM Configuration I have changed to Disabled.
 
I have saved these settings and booted back into the bios where i have boot overrided with the UEFI USB stick.
 
Still not seeing the drive in windows or in the bios!
 
HELP!!! 
 
 

 
I too have a SM951 (128GB) and am having the very same issues. I even went as far as putting the SM951 into another Z97 rig, boots right up into Windows 10! 1st time! Gotta be a issue with the board.....

I'm seeing a few issues with this board on the forums.  My guess is to either wait for a BIOS update that will fix most issues or give a call to their 24/7 tech support and see what they say.

Well Jacob emailed me, tried what he suggested and it worked like a charm! Guess I just overlooked one step. :D

We tested it without any issues, make sure to select boot mode to UEFI then you should see the windows boot manager.
 
You can also try setting Legacy mode.

I have tried with UEFI mode enabled as in the attached pic above.
 
Havent tried legacy mode.  Will try that when I get home.

It seems that the Micro 2 board issue with m.2 is under investigation at this time - as posted on a different thread on this forum.
 
Can someone confirm this?

We have identified the bug and plan to fix in upcoming BIOS.

I had absolutely no difficulty setting up a SM951 with a Win10 boot on this board.

• Have your USB3 Windows install stick handy.
• Enable the M.2 slot. You should see the Samsung in the drive list on the SATA page.
• Set boot mode to Legacy, and make USB the top boot pick. This board isn't currently booting from USB in UEFI boot mode, as I documented in my thread. We don't need UEFI mode yet anyway.
• Boot that stick and run the installer. Windows should be able to find the SM951.
• On the first installer reboot, DEL into the bios setup as soon as the system posts. Always, always grab the bios setup of the first reboot on any OS install, even if it's just to check your settings one last time before letting the OS attempt it's first boot.
• In our case, we are changing boot mode to UEFI and resorting the boot order to put the generic Hard Drive entry at the top. This is also a good time to pull the USB stick since that isn't needed anymore.
• Save and reset; unless I forgot something (I'm writing this from memory and I've slept a few times since then), that really should be all there is to it.

The only thing remotely tricky here is understanding that your install stick wants to boot in Legacy mode and the M.2 wants to boot in UEFI mode. Using a USB3 stick this way will install Win10 kit and kaboodle (including manually turning off all the privacy violations, lol) in under 10 minutes.
 
Also, you can use the M.2 drive in Legacy boot mode all day as a secondary SATA drive; you just won't be able to boot from it that way.

If the bios can't see it, Windows is not going to find it. That smells like a hardware/firmware problem that may require a support ticket and/or RMA. Make sure you understand your return window on the SM951 in case it's a dud.
 
If I get home at a decent hour tonight, perhaps I'll try taking screen shots of my setup, but I distinctly recall seeing the SM951 in the drive list after enabling the M.2 feature. In EVGA's UEFI display there is a graphic representation of the system's current PCI-E configuration (a row of bars as I recall). That display should reflect the disabled PE3 slot. So in my case with a i7-5820K, the display indicates PE1 x16, PE2 x8, PE3 --.
 
If the config shows PE3 is disabled, M.2 is enabled, and the bios cannot find the Samsung after a save-n-reset, then all I can suggest is making sure the card is seated correctly, and then escalating to your vendors beyond that. Good luck!

Thanks again for the quick reply kurt, I will have another play today/tomorrow just in case - was late at night last time I tried so always the chance I was missing something blindingly obvious!
 
I also have a Crucial MX200 M.2 2280 SSD kicking around from another build which I could try with the Micro2, but am I correct in thinking this will be incompatible since the Crucial M.2s are SATA based whereas the Micro2 only supports PCIE M.2?

 
If its a SATA interface and not a PCI-E, it won't work, AFAIK.

Cool! Thanks - have emailed you! 

Thanks for this Jacob!
