Is SteamOS ready to replace Windows? I installed it so you don’t have to

June 30, 2026

The release of the Steam Machine has certainly stirred a mix of curiosity and skepticism within the gaming community. Initially announced with a starting price of ,049 in the U.S. and £879 in the U.K., the hardware’s cost has raised eyebrows. However, this launch has inadvertently sparked a growing interest in SteamOS, prompting many users to consider installing it on their existing systems. The question remains: Is SteamOS poised to replace Windows as the go-to platform for PC gaming? To find out, I embarked on my own exploration.

SteamOS: A Work in Progress

Upon diving into the experience, it became clear that SteamOS is not yet ready to dethrone Windows. Valve itself acknowledges that the operating system is still in beta, applicable primarily to the Steam Deck, Steam Machine, and Lenovo Legion Go S. Compatibility is limited, with only a small percentage of the Steam user base—approximately 19.13%—utilizing AMD GPUs, while Nvidia continues to dominate with a staggering 72.42% market share.

The disparity in GPU support stems from how manufacturers approach Linux. AMD offers broad support through open-source drivers, which Valve has actively contributed to, enhancing their gaming capabilities. In contrast, Nvidia’s proprietary driver stack requires Valve to engage more closely, complicating the installation process for SteamOS. Other Linux distributions, like Bazzite, have devised workarounds, but for a major player like Valve, direct collaboration with Nvidia is essential.

Fortunately, I belong to that 19% with a compatible setup, featuring a Ryzen 5900X paired with a Radeon RX 6800. Eager to explore SteamOS, I downloaded the bootable recovery installer and utilized Rufus to transfer it onto a USB stick—a task made simple by the multitude of USB drives at my disposal.

Installation Challenges

As I prepared for installation, I stumbled upon an intriguing quirk: while Valve has tacitly supported dual booting on the Steam Deck, any new SteamOS installation using their installer mandates a complete wipe of the NVMe SSD. The scant support documentation from Valve adds to the challenge, leaving DIY PC gamers with little guidance. For those seeking a straightforward experience, this could be a significant hurdle.

Fortunately, the community has been proactive, with many users experimenting with SteamOS on various devices. Following a guide by Josh5 on GitHub, I navigated through the necessary BIOS and Windows settings adjustments, shrank my Windows partitions, and booted from the USB flash drive. The installer, a portable version of the Linux OS, came equipped with essential utilities.

Recently, Josh5 introduced a GUI utility to streamline the installation process, but I found the command line method to be more reliable. After some trial and error with copy-paste commands—each application seemingly requiring different keystrokes—I successfully rebooted into SteamOS and its setup utility.

Networking Woes

However, my excitement was short-lived. After selecting my language and time zone, the downstairs PC failed to display any available networks, despite being connected via Ethernet and having internet access through the USB installer. In contrast, my other PC managed to show both wired and wireless options but encountered an update failure due to a lack of network connectivity.

At this point, I realized I had ventured deeper into the installation process than the average gamer might prefer. Partitioning drives, adjusting BIOS settings, and executing command line scripts are not tasks that most users would relish, underscoring the value of the Steam Machine in the gaming ecosystem. There is potential for companies like Lenovo or Asus to create direct competitors to the Steam Machine, while boutique PC builders could offer semi-customized SteamOS systems.

After some diligent searching online—relying solely on good old-fashioned research rather than AI—I managed to resolve the networking issues. For the upstairs PC, a command line update was necessary, while the downstairs PC required a workaround for its lack of a Wi-Fi card, which impeded the network stack from loading.

Exploring SteamOS

With SteamOS successfully installed, I began to explore its features as a gaming platform. The interface immediately introduced a more console-like experience to my living room gaming setup. With just a few power button presses, I could grab a gamepad and dive into a user-friendly UI designed for gaming.

While the Steam Machine offers additional features like HDMI-CEC, the streamlined approach of SteamOS presents a compelling alternative for gamers who prefer a direct path to their games, bypassing the traditional login screens.

So, is SteamOS ready to replace your Windows installation? For certain gamers, it may very well be a viable option, but it remains fraught with challenges for those who are not seasoned tinkerers or DIY enthusiasts. The command line interface can evoke memories of earlier computing eras, and the installation process is not without its hiccups. Ultimately, the most daunting aspect may be the prospect of reverting back to Windows and navigating the complexities of partition management.
