Target disk mode -big sur

2018 MacBook Air 90gb free of 128gb

running latest Catalina


Is there a way to upgrade the MacOS?


Each time I try. It kicks me into Target disk mode. I don't have another MacBook to connect.


Currently just booted up with command, shift, options R (command R wouldn't work.)


This should install Mojave??? Do I just give up on big sur and reinstall Catalina? Or is it easier to install big sur after Mojave?

MacBook Air 13″, macOS 10.15
