I just installed desktop 15.10 but met the same problem described here http://ubuntuforums.org/showthread.php?t=2309056
ubuntu is installed on /dev/nvme0n1p2 ~ /dev/nvme0n1p5, which is not recognized by gparted
I tried the boot-repair method but it told me "An error occurred during the repair." when it finished running and it still couldn't boot. It sometimes ran into no such device error and booted into a grub cmd like this -
> error: no such device: .......
grub rescue>
I have windows 10 installed on another disk. 950 pro is an empty disk. I tried both automatic install (remove everything on the disk) and manual partition(something else). Can somebody plz help?
With cutting edge hardware, you need the newest versions of software, and sometimes even ppa's to get newer than in standard distributions.
If using gparted, be sure to download the newest version: gparted should be at least version 0.24.0-1 to recognize NVMe devices

Since 16.04 is now released.But be sure to review release notes:

You can burn ubuntu 15.10 in a pen drive and load it up during boot. Start installation, and you will get an option to "remove 15.10 and install it again", select that option and continue. This should resolve your problem!
