I have it as a dual boot option. But, it’s not been booted since November. So I am assured I’ll need to rerun grub when I do decide I need to boot it for something I cannot do in either Linux, or a Windows VM in linux (that’s really a small number of things).
I’m not using VST. There’s a few games I got on Microsoft store some years ago which there’s no way (yet) to make run in Linux (at least to my knowledge). But, I don’t feel that much need to play them. At least not enough to boot into windows, complete the huge updates likely waiting and then fix the grub install afterwards just to play a game.
