[Trisquel-users] Libreboot X200 dont boot Trisquel 7 Netinstall

[gaffel]

I have tested Ubuntu 16.04, Ubuntu Mate 16.04, Ubuntu XFCE 16.04, Linux Mint  
MATE 17.3 and all boot but I dont get Trisquel 7 Netinstall to boot from the  
USB stick. When I choose USB in Libreboot it stands there for a couple of  
mins and then comes back to Libreboot menu.

USB flash method I use

Suggestions?
