FYI, everything is currently working under windows 10, however i was unable to install windows 7.

Components are.

i7-6700k
Maximus VIII hero
Corsair Vengence LED 2X16GB
Samsung 950PRO

(no other HDD/SSD or CD/DVD drives)

I used rufus to make a bootable USB using a proper win7 ISO.

I managed to get without problems to windows installation, windows detects the 950 pro, and i installed windows

After the first reboot occurs, just as it loads windows, i get a blue screen with the error "inaccessible boot device", this loops forever.

I tried to repair as the help page in windows tells me to no effect (cannot actually repair anything, cannot run dskchk /f at all etc)
I updated the bios to the latest version, same problem
I used a different win7 ISO, same problem (fresh partition etc)

Using windows repair tools i can go to disk management to see the 4 partitions the 16MB MSR one is listed as "not healthy"

Basically i just have no idea, is it even suppose to work, i dont have a spare normal SSD to see if thats working, but i can only guess that it must be the 950PRO that is giving the problems. Seeing as how everything is working fine on windows 10, there must be no hardware problems at all, and everything is properly connected etc.

So yea, looks like i'll be using windows 10 for now, however im sure i will encounter this problem again, perhaps a friend wants to upgrade etc, so i would like to know if there is any solution. I've spent some time googling it unsuccessfully, from what i can see, many people seem to have problems with windows 7 on 950pro or other nvme drives.

PS: I cannot test any solutions myself
 
versions of Windows below Win 10 are locked out at a hardware level due to a sneaky partnership between Intel and Microsoft. It has been like that for awhile now. It is not possible AFAIK to run a lower version of Windows as a fresh install than 10 on 6XXX skylake CPUs at this point as far as I know.

This is interesting...

I have not heard of this until of now. I built a new rig up for my son about a month or two ago with an Asus Z170 Pro Gamer and an Intel i7 6700k.
Because my sons old board was an Asus Z77 I just took out his OS SSD and slung it in the new build and just updated the drivers. Everything rang pretty smooth apart from one issue, he kept getting a black screen and had to reboot.

So do I read it right the new hardware will NOT run Win 7 ?

As of yesterday to eliminate any driver\chipset issue I did a fresh install of Win 10. Running Win 7 could have been the problem all along.

Or am I reading this wrong ?
