you may need to experiment with different booter quirks

Can you try to configure it for me? As you can see I'm not very good in this.

not really as i don't have the same laptop as you to be able to test it

Do you then have any ideas what I exactly should change in the config?

it will most likely be the section with:
DevirtualiseMmio
ProtectUefiServices
RebuildAppleMemoryMap
SyncRuntimePermissions

etc...

enabling/disabling various ones (resetting nvram after each test) may start the boot process

Now I reinstalled the complete USB and it says in a popup: MyGetFileSize: File not found. could that be the problem? And it's stuck at "Updating the MBR with boot0..."

Fixed it already and where's the DVMT-Prealloc stuff? In my BIOS isn't the option so I thought it could be the option I should change in the config.
