BUSTER
Reviewing the config you're using reappeared the resizebar option set to 0
you should leave it at -1
You don't have in the bios that option I guess
Putting parameters for Nvidia, in my experience is not useful
You have not yet installed the operating system and therefore the Nvidia driver
the system will start, when it starts , it will start in VESA model
The error message it gave you after choosing the language, does not depend on errors due to MMIO or Nvidia or even slides
More likely a corruption of the installation
I would advise every attempt you make to clean the NVRAM and be very patient without giving up
For me you are very close to the success of the first step (installation in VESA)
