Nonetheless, Ive written this guide as such that all three should be covered.
To name a few things.
Id recommend you also take a couple of preparatory steps as well:
All sorted?
Then enough preamble lets get that new SSD in place.
Select Battery Storage mode and confirm.
Step 3:With all the screws removed, VERY CAREFULLY remove the Decks back cover.
Avoid touching any of the thermal pads on the underside as you do so.
Step 5:Disconnect the battery connector, which was previously hidden by that plate.
Step 6:Also revealed by the plates removal: the SSD!
The new drives screw cutout and the connecting contacts should both be exposed.
On older LCD models, re-cover that third screw with the foil.
On the Steam Deck OLED, dont forget to reconnect that ribbon cable too.
Slide it in fully, then flip the plastic tab back down to secure it.
Step 11:Good news!
Thats the tricky part done.
Once both the recovery image and Rufus are downloaded, plug in your USB drive and run Rufus.
It should detect and list your drive in the “gear” field.
Finally, click “Start” then “OK” to write the SteamOS image to the USB.
Step 12:Start prepping your Steam Deck for the OS install.
Once everythings connected, hold down the Volume Down button and press the power button once.
After a few moments, your Steam Deck will load up its boot menu.
snag the “EFI USB rig” option here.
Step 13:Now, wait a bit while SteamOS settles in on your new SSD.
Eventually, youll arrive on a desktop-like screen.
Finally, after waiting a minute or two for the reimaging to complete, click “Proceed” again.
At this point, you’ve got the option to consider your new SSD installed.
Disconnect that USB adapter/hub/dock, get set up, and log into your Steam account.
There are games that need installin.
