Hey,

I've got a problem and it's driving me nuts, I have googled this problem and see loads of threads with the same issue and never a decent answer.

System:
Gigabyte Aorus Gaming 7 Z270
I7-7700k
16GB Gskill TridentZ RGB Ram
980Ti
3 normal SSD's (840 evo, 850 evo, crucial mx500)
1HDD

Last month I bought the Samsung 960 EVO NVME drive and installed in on the top slot in my mobo. At that point I used it to store games and it worked fine. The only thing I noticed is that I didn't show up in Samsung Magician.

Yesterday I wanted to use the drive as my bootdrive with windows and the 3 ssd's I would set up in raid 0, the hdd I would remove from the system because it's old and very slow.
Made a bootable usb thumb drive with windows 10, disconnected the other drives and got to the windows install screen.
The 960 showed up at disk 2 with one main partition. On the install window I got a warning saying that the drive could not be used as a bootdrive and I should check the diskcontroller in my bios. I went ahead and continued the install but yep, the drive installed windows but couldn't boot.
Next I retried and removed the partition from the drive and created a new one this time I got 4 partitions but still the error message about not being bootable.

I checked my bios and I don't know where to look for this diskcontroller and if this would solve my problem. I also find it odd that the drive doesn't appear in Samsung Magician.

I have the latest bios installed and I believe I installed the drivers when I first got the drive last month.

I don't know what to do anymore.
 
This looks like a motherboard hardware fault with M.2 port to me. I advise contacting Gigabyte about this problem first. Things you can do yourself: check the other M.2 slot if the board has it (if only for a test, to see if you got same problem); check the drive in another machine (to see if it shows up in Magician).
 
Hardware failures can be very strange. I had a GPU once that worked fine with all games save 3D ones - the moment I would run 3D game the system would crash. It is absolutely possible that drive works fine as storage and yet it is not bootable due to hardware failure.
