Fujitsu Esprimo p420 E85+ Won't install big sur

Hi all I'm new to the hackintosh world. I have a Mac Mini late 2014, and I recently get a desktop as i wrote in the title. My goal is to get big sur working on the desktop machine, using opencore, but after creating the USB the pc just refuse starting installing. It stuck on that screen.IMG_9659.jpg
Here my EFI folder.
My config:
i3 4130
Mobo Fujitsu, don't know the exact model
8GB Ram
Integrated Graphics 4400
