SteamOS 3.7 & Beyond: Your DIY Installation Guide
Beyond official partnerships, Valve has made SteamOS 3.7 available as a public beta, significantly improving support for generic AMD-based PCs. This includes other popular handhelds like the Asus ROG Ally and the original Lenovo Legion Go, which were previously limited to community-driven Linux distributions like Bazzite for a Steam Deck-like experience. This means that if you own compatible hardware, you can now download and install a working copy of SteamOS yourself. This empowers users to take control of their handheld experience, potentially gaining the benefits of Valve’s optimized software and game compatibility without waiting for official ‘Powered by SteamOS’ devices, offering a fresh lease on life for existing hardware.
To install SteamOS 3.7 on your non-Steam Deck hardware, you MUST have AMD hardware (CPU, GPU, chipset) and an NVMe SSD. Additionally, you will need to DISABLE Secure Boot in your PC’s BIOS/UEFI settings. Without these, the installation will likely fail or lead to significant compatibility issues.
