Steam Deck x Windows 11 Full Guide for Dual Boot or SD Card Installation

In this video, I go over the full process for both installing Windows 11 on an SD card (as the least invasive option for your Steam Deck) as well as installing Windows 11 on a fresh SSD. I also show you how to replace your Steam Deck SSD and go through the recovery process.

In this video, I also will show gaming performance with Call of Duty Modern Warfare 2019 on each of the configurations.
