I'm currently building a Hackintosh. (my laptop: MateBook X Pro) I followed the instructions for installing MACOS exactly, but when I'm in the Clover boot screen and trying to boot Mac OS Mojave, my PC restarts (which is also in the instructions) and then happens so nothing a black picture. It doesn't actually boot MacOS, so to speak. What can I do that it boots or I run MacOS on my MateBook?
Nothing.
Ask for help in a community that works with Hackintoshs. Every non-Apple computer has individual hardware and setting options, which is exactly why a Hackintosh is always problematic.
If you absolutely want to have macOS and a new Mac is too expensive for you, buy a used one.
