UniBeast is a tool by MacMan and tonymacx86 to create a bootable USB drive from any Mac App Store purchased copy of Mac OS.
This all-in-one bootable USB drive can also be used as a rescue boot drive for system recovery.
UniBeast 9 uses Clover as the bootloader and supports macOS...

then i booted my pc from my usb stick and i started it with the boot command -v and -x .
And thats the error that shown...
