Lenovo Y50-70 USB boot black screen

So I'm trying to boot from USB on my Lenovo, I did everything that is written in Rehabman's guide, but I got stuck on a black screen after the apple logo. It loads for a couple of minutes and when it finishes I only get a black screen with sometimes flashing parts of the screen. Flashing I mean by that I can see whats behind the black screen, the installer loaded, everything looks fine, for a split second, till I can see it, after it only black screen.

I set the BIOS according to Rehabman's guide:

Default options set to Windows 8.- secure boot is disabled- enable Legacy Boot (but UEFI first)

If I set it only UEFI boot, I get this https://preview.redd.it/axvt8lp1gne01.jpg?width=960&crop=smart&auto=webp&s=94af392ea5d19488489452275d3b4db61ad64538

For config file I'm using Rehabman's config_HD4600_4400_4200.plist

Kexts: Lilu, Whatevergreen, VoodooPS2Controller, FakeSMC.
