Samsung 950 PRO 512GB M.2 NVMe not recognised after installing windows 10

Hello everyone,

I have encountered a problem with Samsung 950 PRO 512GB M.2 NVMe. I would appreciate your help as my knowledge in hardware and software is minimal. So thank you in advance.

I have just finished installing windows 10 in a new pc while using old HDD drives I had from my older pc. I have purchased Samsung 950 PRO 512GB M.2 NVMe to be my boot drive and purchased the samsung 850 ssd for regular storage.

In addition to the above I already had 2 older HDDs from my previous pc that I connected them for extra storage.
When I started the windows 10 installation I chose custom so that I could choose the NVME ssd for installation and boot, however, I noticed that I couldn't differentiate between the two samsung ssds as both were 512 gb and windows only called each 'drive 1 or drive 2' and so on.

So, I randomly chose one and I think it appears to be the 850 that was installed, to my dismay.
Now the issue is that I cannot locate the NVME drive on 'this pc' although it is seen in BIOS for boot drive. To confuse me even more, in the BIOS I cannot see the M_1 slot when I go to advenced then storage in BIOS, the other 3 drives are located by their different satas.
I don't know what to do.
to summarise I would appreciate it if someone can help me in getting:
1 - the samsung 950 to be my installed windows, currently it says its the boot drive but i dont know if it needs to have windows installed on it
2 - to have the NVME recognised by windows so I can use it for storage and so on.

my mother board is ASROCK Z170 EXTREME 7+
cpu intel i7-6700k

Thank you so much for your kind help.

  1. You probably should install windows with only the boot drive installed. Then after installing the MB drivers and setting up the BIOS and memory, install the other drives.

    That link didn't help alot, he was talking about his RAID setup and he hasn't installed windows yet. I have already installed windows and part of the problem is that I dont know how to reinstall it again in a different driver. The option to boot from the USB stick I used to install windows does not show up anymore.
    I just don't know what to do at this point. :(
  3. can someone help? I still can't find an answer online to this issue.
  4. Just to ascertain that you do have a problem...

    1. When you boot your system, can we assume it boots without incident and properly functions?

    2. Assuming you've answered "yes" to the above, can you tell us what Disk Management reports re the configuration of your system as it involves all the disks detected in your system?

    3. And do all these listed disks reflect drive letters?

    4. Samsung issued a driver for the 950 Pro earlier this year. Ensure that it's been installed in the system. See...
  5. Thank you for your reply. Yes my mistake I found it in disk management but it was unallocated. So I did go through the wizard and its there in my my pc as a storage drive.

    Now I want this drive to be my boot drive, does that mean I have to reinstall windows? if so I tried earlier with the usb stick that I had originally installed windows with it but the system just does not want to recognize it as boot drive when press F11, the usb stick is not there. So, what do you think I can do to reinstall windows and make the new drive my boot drive?

    Thank you very much!

    From your original query it appears that you did install the OS on the Samsung 850 Pro, albeit mistakenly. I'm not sure if I correctly understand this since you have not indicated that the system boots the OS to that drive and does so without a problem and functions properly.

    So if you have a viable OS installed on that drive and you are satisfied that it is functioning properly you would have the option of using the Samsung Data Migration program to clone its contents to the 950 Pro and then establishing that latter drive as your new boot drive.

    Or simply fresh-install the OS onto the 950 if that's what you prefer.

    If you choose the fresh-install route, when you boot the system and access the boot menu via the F11 key, the Windows Media Tool flash drive should be listed as both a USB device and a UEFI device. Assuming the 950 is MBR partitioned, select the USB option from the boot menu; if problems with OS setup arise as a consequence, select the UEFI option from the boot menu.
  7. Thank you for your reply.

    Correct, everything is working properly except that I do want the boot drive to be the PCIE 950 PRO. I did not know about the samsung migration tool. I will give it a try.

    Thank you very much for your reply.
  8. Do so. One more thing...

    Following the disk-cloning operation, disconnect the 850 Pro (your "destination" disk) from the system and boot ONLY with the 950 Pro connected - no other drives. Assuming the system thereafter boots & functions properly then you can reconnect the 850 Pro and any other secondary drives desired.
  9. If the cloning does not work, disconnect all drives except the one you want to be the boot drive. I'd make sure that drive is in the first port, usually sata0 or sata1. After windows install, install the MB drivers get you system running, set up the BIOS making sure the memory speed & timings are correct. Once your system is running right, install the other drives. I'd do it one drive at a time.
