donot agree.
I run Ubuntu 21.10 in dual boot with W11, no problems. normally Ubuntu boots via Grub file and I have to manually select W11 if wanted. Hardly run W11 and its programs but that doesn’t matter.
Anyway, I solved my problems on my own. I don’t need anyone to help.
I just bought a cheap HP Win11 machine to use as a game console, connected to my main computer with a KVM. Runs all the games (except for Metro 2033, which seems to be all messed up) and I can shift back over to the main machine with three Linux distros with just the press of a button.
