Both Windows 10 and 11 can be installed on Steam Deck, though doing so wipes the device. Dual boot is currently not available with Steam Deck, though it is reportedly coming in a future update.
Those who would rather keep the default Linux-based SteamOS that the device ships with can still take advantage of Xbox Game Pass and Xbox Cloud Gaming. In fact, going this route—and having all the advantages of running Steam games natively while having access to Xbox Cloud Gaming within a browser—is pretty close to ideal.
