If you want dual boot, then usually: install windows, repartition and install linux.

But… Why not just run windows as a vm on your linux desktop? Not wine and the likes, just a vm in virtualbox or boxes or kvm

Because it will have errors with device access I am almost 100% sure. But yeah, I’ll try it with GNOME Boxes or something but I already know it’s going to start talking about udev rules and stuff like that and then it’s another time sink to figure out.

I tried going to the library to use their windows but you cant download anything (like the garmin updater) so I don’t even know what the point is of having them there honestly.
