on my old EFI-BACKUP(Clover) there is no kext Radeonboost in Kext-folder.

You can delete it if you like. It really doesn't matter for Navi cards. It doesn't do anything for them.

How far does the progress bar get?

Are you using DisplayPort or HDMI? Can you try switching to a different connection?

I don't know what can be wrong. WhateverGreen should enable all the video out ports on your 5700 XT...

Thank you, update without errors and Big Sur is working fine.

I wonder about the first startup message:
The machine is booting without problems. On the black field there is my MAC Adress of the Ethernet Adapter without :.
I inserted it on the ROM key field.
May i just ignore this?

Put a working EFI on the EFI partition of a USB flash drive and boot from the USB flash drive.

Sorry for my question , i tried under linux, but efi is read only, because of jounaling. How do i create an USB Stick with efi partition? I have an macbook air with big sur. With Unibeat i can only create an usb stick with catalina.

On your MacBook:
Initialize your USB flash drive as HFS+/GUID.
Mount the EFI partition.
Copy/paste a working EFI to the EFI partition of the USB flash drive.

Boot from USB flash drive.
