Good night,
I made the pen-drive to install Big Sur,
I fix the bios to start it, open OpenCore, I click to install it loads halfway and I get the following message "http://support.apple.com/mac/startup" as in the photo below,
The image I took from the Apple website, but the problem is the same,
My computer settings:
16 GB
Processor: i5-8300H @ 2.30GHz
Graphics: GTX 1050
I appreciate the help.
sorry for the english is from google translator.
