PC specifications:

Patience (this was hard for me)
Make sure your motherboard is on the latest available BIOS.
Make a Bootable USB stick (from a actual Mac) using this procedure: https://www.tonymacx86.com/threads/how-to-create-a-macos-catalina-public-beta-installation-usb.278188/

I didn’t do anything at all with the Library/Extensions folder myself (it has lots of files in in though). For kexts, I only used the EFI/CLOVER/kexts/Other/ folder.

Make sure (!) you are using the latest kexts from the internet:

Step 1: After power on, press F12 to select bootable USB. Just boot from the USB boot disk and install. Be sure to insert the USB into the USB 2.0 port.
Step 2: Install macOS Catalina on Any Supported Intel-based PC. I have omitted the detailed steps above. Only thing you should do, is during the entire process, boot via the USB stick.
Step 3 (perhaps this step is redundant to step 4, but I did it anyhow): After installation is complete, install Clover (Clover_V2.5k_r5098 by Dids), install Clover Configurator and update it first. After that, mount the EFI of the SSD with Clover Configurator.
Step 4: Delete the EFI folder of the SSD (intel SSD) with Catalina installed and EFI.ZIP Please paste and unzip. And extract it in your EFI folder.
Step 5: Start Kext Utility Prepare the permissions.
Step 6: Restart
Step 7: Select and start the SSD on which Catalina is installed on.
