To install SteamOS on a replacement Steam Deck SSD, create a recovery USB drive using Valve’s SteamOS recovery image, boot the Deck from that drive, then choose Wipe Device & Install SteamOS. That option fully wipes the device and installs stock SteamOS, so use it for a clean installation on a new drive—not to preserve existing local content.
Check the Deck model and replacement SSD
The physical SSD replacement and SteamOS installation are separate tasks. The cited iFixit teardown covers the LCD Steam Deck and identifies its internal drive as a single-sided M.2 2230 SSD. It directs OLED owners to a separate, OLED-specific guide; do not assume the LCD teardown applies to an OLED model. See iFixit’s Steam Deck SSD Replacement guide for model-specific disassembly and reassembly instructions.

For the LCD model, the guide’s form-factor specification is a single-sided M.2 2230 SSD. It does not establish a particular brand, capacity, price, or performance tier as the right choice. Follow the full guide for the physical swap; it lists Phillips drivers and opening picks among the tools and recommends standard electrostatic-discharge precautions.

- A replacement SSD installed in the Deck.
- A USB drive with at least 8 GB of storage. Writing the recovery image formats the USB drive, so use one whose contents can be erased.
- A computer to download and write Valve’s recovery image to the USB drive.
- A USB connection for the Deck. You can connect the recovery drive directly or through a hub.
Create the SteamOS recovery USB
- Open Valve’s SteamOS Installation and Repair page and download the recovery image for the Steam Deck.
- Write the image to an 8 GB or larger USB drive. Valve recommends Rufus on Windows and Balena Etcher on macOS and Linux. Linux users can also use the command-line method on Valve’s page; follow its current image filename and command rather than relying on a copied command that may have become stale.
- When writing finishes, safely eject the USB drive.
Boot the Deck from the recovery USB
- Shut down the Steam Deck and connect the recovery USB drive, directly or through a hub.
- Hold Volume Up and press Power. After the chime, release Volume Up to enter Boot Manager.
- Select EFI USB Device from the boot options. Valve notes that the screen may remain dark for about a minute while the recovery environment starts.
Choose the right recovery option
For a clean SteamOS installation on a replacement drive, select Wipe Device & Install SteamOS in the recovery desktop. Valve says this option “will fully wipe your device and install stock SteamOS.” When installation finishes, reboot and continue through the SteamOS welcome experience.

For more on recovery alternatives, including factory reset, rollback, and erasing user data, see Valve’s SteamOS Recovery and Troubleshooting page. Its in-system Factory Reset route requires the Deck to boot into Steam; Valve notes that reinstalling SteamOS there may require an active internet connection.

If the recovery environment does not appear
- If the Deck starts its normal installation instead, shut it down and repeat the boot sequence: hold Volume Up, press Power, release Volume Up after the chime, then choose EFI USB Device in Boot Manager.
- If the screen stays dark after selecting the USB device, allow about a minute for the recovery environment to start, as Valve notes this delay can occur.
- If the USB drive is not listed, check that the recovery image was written successfully and that the drive is connected. Re-create the recovery media using the instructions on Valve’s current installation page.
