Good idea. And if @goofsqueak@lemdro.id goes for it and is concerned about the physical drive with Windows potentially tempering with the Linux install or reporting back to MS or whomever else whatever it finds, goofsqueak could unplug the Linux drive before plugging the Windows one, so no physical access to the main system is given to Windows.

And to goofsqueak, any problem with Fortnite on the Switch? I don't play games as services so I wouldn't know, and at least from my experience with offline games, if the problem are graphics, Fortnite from the little I know of, I don't think would lose much in terms of quality.
