Black screen after selecting USB in boot menu

Hello, Yesterday and the day before I have been trying to setup a hackintosh. I used the vanilla method and after following the guide and setting bios settings, it booted into a black screen. I have waited for 10 minutes and nothing happened(no opencore boot selection).

​

My hardware:

CPU: Intel Pentium G3258

GPU: NVIDIA Geforce GTX 780 Ti

Mainboard: Asus H81M-D PLUS

I used opencore vanilla guide: OpenCore Install Guide (dortania.github.io)

The opencore debug text files are empty. I have shared my usb contents below.
