Now I want to install Big Sur...but I'm completely lost on how to configure OpenCore or Clover for my PC. Itried Dortania guide several times. And I always get stucked at "[EB|LOG:EXITBS:START]". Then I tried the Clover EFI you provide here for x79 and the result is almos the same, only this time I get stucked at the line of plus signs. It does not boots the BigSur installer nor the working Catalina installation.
So I first I tried OpenCore, and got stuckd at "[EB|LOG:EXITBS:START]"
Then I tried Clover from here, and got stucked at the plus sign line.
Honestly, I don't know what else to do. I'm completely lost. I don't even remember how many times I tried things I found on the web...but seems that none ver tried to install Big Sur on a CPU like mine. I think the problem has to do with the SSDT...but I have no idea how to make one, and the technical documenttion is beyond my comprehension.
