The Legion Go S became the officially supported SteamOS handheld, while the original Legion Go remained a beta-compatible, more experimental installation.
That distinction matters if you are deciding whether to install SteamOS on an existing Legion Go. It can provide a more console-like interface and a better Steam-focused experience, but the installation can erase Windows, require recovery media, and leave device-specific features such as sleep, TDP controls, or controller wake behavior imperfect.

What was actually tested?
On March 26, 2025, coverage reported that ETA Prime had installed an early SteamOS build on the Legion Go S ahead of the SteamOS-equipped model’s wider availability. The reported process began with a Steam Deck recovery image rather than a polished, ordinary consumer installer. Setup also reportedly required a keyboard and mouse because the handheld’s built-in controls were not immediately recognized.
Community users separately demonstrated SteamOS running on the original Legion Go. Together, the demonstrations established something important but limited: SteamOS could boot and operate on Lenovo’s AMD handheld hardware before the official partner device launched.

They did not establish universal performance gains, reliable battery-life improvements, complete Lenovo hardware support, or a supported installation method for every Legion Go configuration. The original report did not provide an independently controlled benchmark suite, so its performance observations should be treated as reported results from a particular setup—not a guarantee that SteamOS will produce higher frame rates in every game.
The original report described better performance under SteamOS, plausibly because the operating system can impose less desktop overhead than Windows in some situations. Actual results still depend on the game, resolution, power limit, Proton version, graphics stack, shader compilation, frame limiter, and VRR settings.
Why SteamOS was significant on the Legion Go
Windows works on handheld PCs, but its desktop-first design can make basic controller navigation awkward. SteamOS boots directly into a gaming interface designed around gamepads, with integrated Steam updates, suspend-and-resume features, and Proton compatibility for running many Windows games.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteThe appeal is therefore broader than the claim that “Linux is faster.” SteamOS can offer:
- a controller-first interface;
- fewer Windows desktop pop-ups and background processes;
- integrated game, system, and controller settings;
- a more console-like suspend and resume workflow; and
- easy access to Steam’s compatibility information through Proton and the Verified system.
None of those benefits guarantees higher FPS or longer battery life. A handheld’s power limit and the game’s workload usually matter more than the operating system alone.
Valve’s promise before the Legion Go S launch
Valve’s January 7, 2025 announcement provided the context for the early testing. Valve said the Legion Go S would be the first officially licensed handheld to ship with SteamOS, while the work being done for that device would also improve compatibility with other handhelds. Valve also said a beta would be made available ahead of shipping so users could test SteamOS on other hardware.

But “a beta for other devices” was never the same as certifying every handheld as a SteamOS product.

Legion Go S versus original Legion Go: the support difference
| Device | SteamOS status | What that means |
|---|---|---|
| Legion Go S | Officially powered by SteamOS | Designed as a SteamOS partner device, with closer alignment between its firmware, controls, and operating system. |
| Original Legion Go | Beta-compatible | SteamOS can be tested or installed, but it is not equivalent to a fully supported SteamOS product. |
| Steam Deck | Officially powered by SteamOS | Valve’s reference platform with the most mature first-party SteamOS support. |
| ROG Ally and Ally X | Beta compatibility | Support is developing and remains subject to device-specific limitations. |
Valve’s current support documentation separates officially supported “Powered by SteamOS” devices from hardware with beta compatibility. The Legion Go S is in the official group; the original Legion Go is listed in the beta-compatibility group. That is the clearest correction to headlines that treat the two Lenovo handhelds as having identical support.
Valve’s compatibility and recovery documentation should be treated as the authority for the current support distinction. Support can change with future SteamOS releases, so a specific build’s behavior should not be assumed to apply forever.
What changed with SteamOS 3.7?
Valve’s SteamOS 3.7 release notes added official support for the Legion Go S and described improved support for other AMD-powered handhelds, including the original Legion Go and the ROG Ally. The release also included an updated recovery image for the Steam Deck and Legion Go S.

“Improved support” is deliberately weaker than “officially supported.” It means the original Legion Go benefited from Valve’s work, but it did not become identical to the Legion Go S. The two devices have different hardware and firmware, and fixes for one should not automatically be assumed to solve problems on the other.

Can you install SteamOS on an original Legion Go?
Yes, Valve provides a beta-compatibility path for the original Legion Go, but this is an advanced operation—not a routine upgrade comparable to installing a Windows update.
Before attempting it, prepare for the possibility that re-imaging will erase the internal drive. Back up personal files and game saves, save Windows recovery keys, and create Windows installation or recovery media before changing the operating system. You may also need:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- a USB drive of at least 8 GB for the recovery image;
- a USB-C hub with power delivery;
- a keyboard and mouse, especially if the built-in controls do not work during setup;
- another computer to create recovery media; and
- a reliable way to restore Windows if the experiment fails.
Valve’s instructions identify tools such as Rufus or Balena Etcher for writing a recovery image. Secure Boot may need to be disabled on a non-Steam Deck device, although the exact BIOS path varies by firmware version. Select the target disk carefully: choosing the wrong drive during re-imaging can destroy data that was not intended to be removed.
Recovery can also be complicated by a lack of a USB-C hub, a failed bootloader, missing Windows media, firmware mismatches, or a device that will not resume correctly from sleep. Read the current SteamOS recovery guidance and installation instructions immediately before proceeding, because images and procedures can change.

SteamOS relies heavily on Proton, Valve’s compatibility layer for running many Windows games. That makes a large Steam library viable, but it does not make every Windows game compatible.

Potential trouble spots include:

- launchers or external DRM that do not behave correctly under Proton;
- Game Pass PC, which is designed around Windows;
- non-Steam libraries that require extra launcher configuration; and
- desktop applications such as Adobe software and some productivity tools.
A game marked Steam Deck Verified is a useful compatibility signal, not a promise that every title will work perfectly on a Legion Go. The Legion Go’s different controls, display, power modes, and firmware can introduce issues that do not appear on a Steam Deck.
Windows remains the safer choice for users who depend on Xbox Game Pass PC, competitive games with incompatible anti-cheat, several third-party launchers, Lenovo’s complete Windows utility stack, or general desktop applications.
Should an original Legion Go owner install SteamOS?
It may be worthwhile if you:
- mostly play games purchased through Steam;
- want a controller-first interface;
- are comfortable troubleshooting Linux and handheld hardware;
- have complete backups and recovery media; and
- accept that beta compatibility may change after updates.
Windows is probably the better choice if you:
- need Game Pass PC or unsupported anti-cheat games;
- use the Legion Go as a general-purpose Windows computer;
- depend on Lenovo utilities or firmware tools;
- cannot risk losing the existing installation; or
- expect every control, sleep state, dock, display mode, and power profile to work as it does in Windows.
Existing owners have a stronger reason to experiment because they can try SteamOS without buying another handheld. Buying an original Legion Go specifically for SteamOS is harder to justify unless the price is substantially below an officially supported alternative and you are comfortable with its beta status.
What should a buyer choose?
The Legion Go S is the more straightforward choice for someone who wants a larger Lenovo handheld built around SteamOS. Its official status gives it a better alignment between the operating system, controls, firmware, and device-specific support.
The Steam Deck remains the simpler option for buyers who prioritize Valve’s mature first-party ecosystem and recovery experience. The Legion Go S may appeal more to users seeking a larger display or a higher-power handheld, but exact specifications and availability vary by market and SKU. Do not assume that Windows and SteamOS versions with the same product name have identical processors, memory, storage, color, or battery configurations.
Recommended Free Tools
Advanced users can also consider a third-party Linux distribution such as Bazzite, but it is not an interchangeable official SteamOS product. It has its own update, support, and troubleshooting model.
The bottom line on the early test
The 2025 demonstrations were meaningful because they showed Valve’s SteamOS expansion reaching Lenovo hardware before the official partner model launched. But the lasting conclusion is narrower than the headline: the Legion Go S became the official SteamOS device, while the original Legion Go remained a beta-compatible and enthusiast-oriented installation.
For an existing Legion Go owner, SteamOS can make the handheld feel more like a console, especially with a primarily Steam-based library. It is not a universal performance upgrade or a risk-free replacement for Windows. Back up the device, expect missing or changing hardware features, and choose SteamOS only if its controller-first benefits outweigh the compatibility and recovery trade-offs.
