I have a NUC6i5SYK and installed Ubuntu 15.10, which comes with linux kernel 4.2
I tried upgrading the kernel to 4.4.4 (stable) but I can't boot anymore. After passing Grub, I get an error about missing firmware.
Any ideas ?

At this point I suggest waiting for someone else to share a positive experience when installing Ubuntu with this unit, so they can help you how they could make it work.
