To be clear, while the article says this is “official support”, this is only drivers provided by valve.

Per valve:

We are providing these resources as is and are unfortunately unable to offer ‘Windows on Deck’ support.

      Some games have security software that requires Windows. Destiny 2 for example.

          As far as I’m aware, all Steam Decks can dual boot. On my machine you hold volume down on power on to access the boot manager.

          I didn’t partition the internal drive because I wanted to preserve the original install, so I boot from the external SSD for Win 11.
