With the Steam Deck OS beta patch and a new BIOS, which provides the necessary Trusted Firmware Platform Module (fTPM) support, Valve now makes it possible to install Windows 11 on a portable game console for the first time. times. However, the necessary drivers are already available.

BIOS update installs Windows 11

After Valve has already released drivers for Windows 10 on Steam Deck, which are also suitable for Windows 11, the installation of the new OS has so far failed due to an improper BIOS with fTPM support. The now released Steam Deck OS beta patch closes this gap and allows Windows 11 to be installed on laptops for the first time, as confirmed by the official Steam Community release notes.

In addition to updating the BIOS for Windows 11, the developers also worked on the stability of the game console under SteamOS 3.0, battery life and USB-C port compatibility, which should now support supports multiple docking stations and power supplies.

  • Added messages when connecting a charger that does not meet the minimum bar
  • Added unlimited frame rate setting in Quick Access > Performance menu
  • fTPM support added, allowing to install Windows 11
  • Added button combination: press and hold “…” + “Volume Down” to reset PD nodes in cases where Steam Deck is stuck due to an incompatible Type-C device.
  • Updated power LED to dim a few seconds after power events for a better experience in dark environments
  • Improved compatibility with a number of Type-C docking stations and power supplies
  • Improved battery life in idle or very low usage scenarios
  • improved stability
  • Fixed issues where the touchscreen would not work after certain shoes
  • Stable compatibility with some SD cards, especially when used as bootable devices.

There is no official support from Valve

It had already been announced in August last year that Valve and AMD were working on Windows 11 support on Steam Deck. Now that Windows 10 is officially supported, Windows 11 support is still listed as Beta.

There is no dual boot on Steam Deck at the moment

Currently, Steam Deck has no dual-boot capability and can only handle full OS installation. But it should be less because of the Steam Deck itself and more because of the SteamOS 3.0 installation routine, which will only be available with one of the next releases.Provides dual boot wizard‘ Vanne said.

Although Steam Deck is fully dual-boot, the SteamOS installer, which will provide the dual-boot wizard, is not complete at this time.


For users looking to downgrade to SteamOS 3.0 from Windows 10 or Windows 11, Valve has instructions for getting your laptop ready.
