Hello GBouerat, thanks for contacting us through the Intel communities.
It is very important to keep in mind that our NUCs support Windows 7, Windows 8 and Windows 8.1 only.
There are some customers reporting compatibility with Linux flavor OS, however Intel has not validated them. The following link has some for additional support on Linux http://www.intel.com/support/motherboards/desktop/sb/CS-034779.htm
I recommend you to post your question on an OpenELEC community.
