Catalina Troubles on Lenovo G500

[MarcSebastian]

Hey guys, right from the start: I am a beginner. So please bear with me if I made an obvious error that prevented the boot.

So I thought about installing Catalina on my Lenovo G500 laptop.
This Laptop has an i5 - 3340M and runs on 8GB of RAM.
I previously had Sierra installed on it but that was already in 2017. Now I want to start all over and try my luck with Catalina.

Basically what I did is create the boot media using Unibeast. I did not change anything else.

I booted in verbose mode to see where the boot stops.

Right at the start I noticed something weird:

AMF: Only 127/256 slide values are usable!
Valid slides: 0-63, 128-190

The boot stopped with the following message:

apfs_module_start:1683: load: com.apple.filesystems.apfs, v1412.81.1, apfs-1412.81.1, 2020/01/09
0000001.554029 EHC2@: AppleUSBEHCIPCI::AcquireOSOwnership: unable to take control from BIOS
0000001.562036 EHC1@: AppleUSBEHCIPCI::AcquireOSOwnership: unable to take control from BIOS

The Config.plist is attached.

I really hope that someone can help me fix this issue. Maybe Catalina doesn´t even run at all on this Laptop?

Thanks in advance to everyone who takes their time to reply. I really appreciate your help.

Did you fix this and get it to work? Currently trying to get it to work on the same laptop.

It is a SSDT-EC.aml file, this is now required for most systems in Catalina.
