I tried to installed Ubuntu 15.10 on the NUC6i3 using a Samsung 950 Pro PCIe NVME SSD. Booting USB drive in UEFI mode was possible and the system runs ok. Installation itself also without problem. After restart the NUC can't find a boot device. Booting the USB drive again I looked up some details: (1) Partitions seem to be ok on the /dev/nvme0n1 (2) EFI boot entries do NOT look ok, somehow destroid
Installing Ubuntu 15.04 on the other hand has been posible without problems. Everything but wifi works out of the box.
What excactly is the difference between 15.10 and 15.04 concerning GRUB, EFI and NVME?
