I started to dual boot LMDE about a year ago, and realized how janky Windows is. So many tweaks and little things that I just "put up with" that I never really paid attention to like when 12 programs all fight to steal focus on startup.
I run hardened windows 10 but now for no reason it's displaying the "Activate Windows" watermark whenever I deny internet access to the system host, which I have done for years without issue. This is the nail in the coffin for me. My system is gonna be pure linux soon, bye bye windows
Also make sure your games drive is not formated exfat. I tried this process with my steam library switching from windows to lmde, but Steam on linux needs access to a file sysyem with symlink support (e.g. ext4) to work properly.
