Initially i thought this was going to be easy, unfortunately all distros i tried to boot from gave me exactly the same result: EUFI 32bit shell. Never ever booted from the usb stick.
Finally found these two posts:
Copied Debian Multiarch 8 on a usb stick using dd (from
http://cdimage.debian.org/debian-cd/current/multi-arch/iso-dvd/ )
Switch off secure boot.
So now for the first time i got past the eufi shell!
Install runs ok, didn't find a network device (should be wireless), boots but doesn't go into graphics. Log in and startx doesn't seem to make it very happy: looks like the graphics mode is on,but still shows the prompt. Not that it does anything. I can switch to other terminal using ctrl+alt+Fx.
Update: saw that there is info on the Ockel website on how to do this:
