How easy it was ! tried first to install Windows7 on my Intel NUC, NUC6CAYH which was a no go....
then i made a bootstick with a 16GB USB SanDisk memory stick, NUC in default settings, only made usb stick boot first via F2,
and all went smoothly, later i switched hdmi cec off, because i already have a hdmi switch in my setup.
Installed 1TB SSD and 16GB RAM.
Thankyou, people, who worked on this ! they did a good job ! 
Have everything working, WiFi, Ethernet, Bluetooth, IR (XBox Infrared remote control with wake up feature working)
My first try was an Android TV Box the Xiaomi X96 Max 4GB RAM 64GB RAM,(with Kodi already on it) this was no success,
much to flakey, needs too much work to get normal performance, so i gave up on it.
LibreELEC on my NUC no problems at all !
