Trying to install Big Sur, screen goes black, then computer shuts off.

So I have my hackintosh built. It is a dual boot system. So I was trying to install High Sierra with clover. Yesterday, clover started, and gave me the option of installing Sierra. When I did, the screen was black. I waited for 20 minutes, and nothing happened so I shut it off.
Today, I redid the setup on the bootable usb, and tried again, this time, when I selected the USB for the boot drive on the bios, the screen went black. I saw a blinking cursor on the top right, then it disappeared, and a very thin line of weird distorted colours appeared on the bottom edge of the screen, then the computer shut off, and if you let it sit for a minute, it will start back up and go back to bios.
some suggested my hardware might be too new for high sierra.
So I did the same thing, this time using Big Sur. The same thing happened. I’m trying to get a hold of the logs, but I can’t seem to access them at the moment.
My build has a i9-10900KF, ASUS ROG Z490-G motherboard, and a Sapphire 11265-0520G Radeon graphics card. Any possible theories would be appreciated.

Have you set the correct BIOS options as described in the Installation Guide (for Catalina)?

You have a system with 10th generation Intel hardware, and Clover 5123 or earlier won't work with it (which means USB sticks made by Unibeast won't work). You will have to use OpenCore or Clover 5124 and later as bootloader.

Until recently I am also convinced that you can't install High Sierra or Mojave on a 10th generation Intel system, but there is a new guide here that prove me wrong :

[GUIDE] OC 10.13.6 Z490 Gigabyte Aorus Xtreme + Core i5 10400 / i9 11900K + Nvidia GTX 1060

Not long ago, it was said that it was impossible to boot a Z490 based 11-gen system on High Sierra, and it was also said that it could not run Opencore. Well folks, this is the guide you've all been waiting for! This system is both High Sierra AND Mojave compatible...

So if you wish to install and run High Sierra or Mojave on your system you can refer to that and try again. But Catalina and Big Sur has native support for 10th generation Intel hardware and is more suitable.
