Users who wanted to experience SteamOS had no choice but to use an alternative OS like Bazzite. However, the announcement of SteamOS support for other devices gave a lot of users hope. Since then, Valve has been hard at work to bring its OS to third-party handhelds, and the company has finally released it for the Lenovo Legion Go S, ASUS ROG Ally, and more.

SteamOS will be pre-installed on the Lenovo Legion Go S, which is launching in a couple of days. However, you can also install it on the Windows version of the Legion Go S, which was launched earlier. In this article, we will explain everything you need to know about the release of SteamOS for other handhelds.

During the CES 2025 event, Valve announced that other handhelds will receive SteamOS support if the manufacturer partners with the company. Those devices would then receive a “Powered by SteamOS” branding and an official build from Valve. The Lenovo Legion Go S was the first handheld device officially announced to receive SteamOS.

Valve has finally published the SteamOS 3.7.8 recovery image, which works for both the Lenovo Legion Go S and ROG Ally. For the Legion Go S, this recovery image can be used to either reinstall SteamOS or install it for the first time on the Windows version of the device. You can also install it on the ASUS ROG Ally.

Coincidentally, this recovery image can also be used for other handhelds like the newly announced MSI Claw A8, which will have an AMD chip. However, some features may not work, such as TDP control, since there’s no official support yet. Unfortunately, you can’t use the recovery image for Intel-based MSI Claw handheld devices, as they are powered by Intel CPUs.

With that said, you can download the recovery image from the official Steam website. It includes recovery image links for the Steam Deck, Lenovo Legion Go S, and ASUS ROG Ally.

Steam Deck Also Received the New Update

The Steam Deck also received the SteamOS 3.7.8 update, which brought several changes and updates, including the Linux kernel 6.11, updated Mesa graphics driver base, support for the Proteus Byowave controller, AMD P-State CPU frequency control, and much more. Update your Steam Deck to take advantage of all the new features.
