I was talking to my dad yesterday and he talked about how he dual booted windows and Linux in his college days. I immediately left to download Ubuntu, I feel so dumb for forgetting it’s an option. I literally only use windows so I can play Fortnite with friends. PSA: you can have both Linux and Windows, or you can use a vm in Linux. Be (mostly) free from Microsoft’s clammy hands.
Just install linux 2nd and have it probe foreign OS, and create a linux only boot partition. Grub will then make a chainloader entry to windows boot partition. Linux won’t care if you select windows chainload option, and Windows won’t know it ia being chainloaded. No OS overlap. just set Grub Boot entry as primary boot in BIOS, EFI.
