I think I probably switched off dual booting to vfio around 2015. Before that for dual boot I had just followed the arch wiki and used two separate drives, using grub for booting both windows and arch. I don’t remember having issues with dual boot but setting up vfio for gaming was still very fresh at the time and was not trivial for me.

EDIT: looks like it was 2016 i stopped dual booting and switched to vfio because I built a new computer for it a year later https://imgur.com/gallery/battlestation-4BuoZ Ironically reading that back I have just recently started getting into film photography.
