I booted from a live usb and installed 15.10 but at the end of the installation process, I get an error:
Unable to install GRUB in /dev/nvme.
Next, it gives the option to change where the bootloader is installed but on pressing OK at this point, grub does nothing. I can't find any information regarding /dev/nvme, only /dev/sda which has always been what I've seen doing linux installations in the past. Why is it /dev/nvme now and how do I fix this? Thanks.
EDIT: It's probably also worth noting that I turned off secure boot and switched from UEFI to legacy because the ubuntu installation kept freezing at the purple loading screen on UEFI mode.
You need to tell the installer to install Grub to /dev/nvme0n1 (at least that's how it shows up on my NUC 5i5RYK with an NVMe drive. However, at least in my case, it appears the installer is broken as I still was not be able to boot into the newly installed system.
However, I did find two methods that fix broken Ubuntu 15.10 boot failure after initial install:
Use the GUI program Boot Repair:
The default or "Recommended Repair" doesn't work, but I selected the "Advanced Options" and uncheck "SecureBoot" but keep all other default options then follow the instructions, the system correctly boots to the newly installed OS.

Install Ubuntu 15.04 first, then upgrade to 15.10. As an alternative to running Boot Repair, I found that if I install 15.04, run all updates:
sudo apt-get update
sudo apt-get upgrade
then run
sudo do-release-upgrade -d
then 15.10 will successfully boot.
