Opencore: Black screen after first installation on ASUS K73SV

[aliens72]

I'm try to make a full install of high Sierra with Opencore on an ASUS K73SV with this specs:

CPU Sandy Bridge Intel i7 @3.2
Display. 17.3" 16:9 HD+ (1600x900) LED Backlight
Graphic. NVIDIA® GeForce® GT 540M with 1GB/2GB DDR3 VRAM.

Once complete the installation on HD and restart the system the screen remain black after the picker/loading of the devices.
I try to reinstall again without resolve.
Any suggestions ?
Here is my EFI

To understand: but if I start from HD after the first installation completed, the USB stick only to load the EFI right? If so, why did the key with the EFI run smoothly during installation?
