I've been using Bazzite for about 5 months with no big issues, but now I ran into games unplayable on Linux. I have no experience assembling PCs and my motherboard is hidden behind other components so I definitely don't want to touch it to see if I can add a second drive.

The guides I saw always assume you're installing Linux second and on a separate drive, so my question is, is it realistic for me to install Windows second on the same drive, or is it too risky? Is there any guide for it?
