You are right I tried all ports and it finally booted to the install interface. 

But it’s strange cause only USB 3.1 worked and they were disabled in BIOS as adviced for previous installations procedures. 
Also I had to unplug GTX 1060 from its pcie slot or I was stuck at « DSMOS has arrived »

I am installing right now

thanks man
