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?

See detailed error info here
