com.apple.windowserver error on install

Hi!
I'm having a bit of a trouble when I'm trying to install High Sierra.
Here are my specs:
- GA-Z97-HD3.
- i5 4460.
- GTX 770.
I've created my usb key using tonymacx86's guides, (the terminal command for creating it and then installed clover on the key). I've changed the bios settings, disabled integrated graphics...

The installer begins to boots just fine and at 2/3 of the progress is loops saying:
com.apple.xpc.launchd(1) (com.apple.windowServer) Service only ran for 8 seconds. Pushing respawn out by 10seconds and then nothing more.

My boot args are : dart=0 nv_disable=1 -v

As anybody a clue?
thanks for your help !
