There is a game I am considering getting; it has been out for a few months now, and the devs are specifically blocking it from running under proton with a Kernel Level Anticheat which specifically blocks linux.
Folks on the discussion boards made the point tht it is technically possible to install windows for just one steam game, so I am looking for a guide on how to do that?
I’ve heard that if you don’t activate windows, you can still use it, and if you get the LSTC (?) Version of windows, it is not so annoying.
Does anyone have a guide for how to install windows alongside linux for one game?
If we have a discussion in the comments about whether it is tactically appropriate to give money to a game corporation that requires windows, i guess we can, but i would rather learn how to install windows in the least annoying way possible.


I can confirm you only need to physically disconnect the non-windows target drive during installation, and as long as you offline the remaining drives after connecting them, windows and other drives will be fine with updates (THIS is the most important part, do it in Disk Management on first boot into windows).
I’ve run two Windows instances for years, through multiple OS major updates and never had problems with this setup, before doing the offline drive change to each of them, they would both fuck over each other (I had one for work and one for personal).
One thing I did that may be necessary, is I didn’t let a boot loader handle the dual boot, I only used BIOS to manage changing the boot target when switching over - I was doing dual windows boots at the time so this may actually be fine with grub, so ymmv on that front.
