i want to try ubuntu+kodi dual boot options, i install Ubuntu according to guidelines, i try this 2 time different Ubuntu version but same issu. The problem is after install and restart chromebox first try to boot with ubuntu it seemed the black screen i wait nearly 10 minutes after then reset chromebox and try again boot with ubuntu, second try its showed ubuntu boot options, i select any of them and take the "Kernel panic - not syncing: Fatal exception in interrupt" error, screenshots is fallowing.

Your kernel panic looks like the 4.2 kernel bug I had. The only fix is to use a different kernel-- 4.3 works fine. Or you can revert to 3.19 from Ubuntu 15.04, but it sounds like you're a fresh install so you don't have that option.

So either install 15.04 and then immediately upgrade to 15.10 or focus on getting OpenELEC working. I suggest the latter, unless you're an experienced linux user.
