Boot from Kali ISO in seperate partition on HD

I have a Dell XPS 13 9350 Developer Edition (meaning it comes with Ubuntu 14.04 LTS preinstalled). Kali cannot work on it due to the non-conventional name of the M.2 SSD in the laptop (/dev/nvme0n1).

As an alternative, I have debian 8.5 installed instead, and I want to be able to boot into a Live Kali 2016.1 ISO without a USB drive.

I've done this with gparted and clonezilla Live partitions before, but their grub entries don't seem to work when substituted with a Kali Live ISO instead of their own Live ISOs.

Has anyone else gotten this working?

it's easy man
first creat a folder called " grml " inside the boot directory # don't change that name it's important
to do that ...... # sudo mkdir /boot/grml

seccond install a small program that add your iso to the gub menu # don't worry it'll be automatique :p :p :p

# sudo apt-get install grml-rescueboot

now copy your iso file into /boot/grml

then run # sudo update-grub

and it's okey reboot your computer and you'll find your iso shown in the grub menu ......... enjoy

Didn't work at all.

Added the kai iso to /boot/grml, installed grml, and ran update-grub.

It's listed on grub, but when I select it, it just says "Press any key..." and after I press a key it just backs me out to grub.

added (hd0,2) before every line where it listed the file path "/boot/grml/kali-2016.1-amd64.iso"

Got into a console. (initramfs):

uname -r retuned "kali 4.3.0-amd64" so It half worked. But there's no UI, and startx doesnt do anything.
