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.

    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.
