How do i put the steamos installer on a usb stick

[JoMaZu787]

When I try to put on the single big 8gb .img file on my USB it fails because fat32 only supports 4gb files, but when I try to extract it, there is another file inside it that's bigger than 4gb.

What are you trying to do? Where did you download from?

The only version available from Valves website is a Steam Deck Recovery Image.

If you are trying to reset a Steam Deck then follow the instructions on the download page. You'll need to use something like Belena Etcher to copy the .img file to the USB.

If this is for a regular PC that img file won't work. There is an unofficial version called HoloISO. However you will need an AMD graphics card with either Vega, RDNA1, or RDNA2 gpu.

For anything else the next best alternative is probably ChimeraOS.

Put the Ventoy tool on the USB stick. Then you only need to copy the image into the root directory and you can boot from the USB stick. You can also copy several images on the stick, you get a kind of boot manager where you can select the image you want to start.

And note that of my pre-poster!

The old SteamOS 2 is way outdated thus it looks like Valve have removed it and temporarily pointed links to the Steam Deck restore image.

SteamOS 3 has not been officially released for other, non-Steam Deck, hardware yet.

If you want SteamOS 3 for regular PC you have 4 unofficial options:

1) If you have a Vega through RDNA2 AMD GPU then there's the unofficial HoloISO build.

2) WineSapOS seems to be similar to HoloISO, based on the Steam Deck restore image, but boots to Desktop instead of Game Mode.

3) ChimeraOS offers a very similar gaming focused environment to HoloISO/SteamOS3 but will run on non-AMD hardware.

4) You can install just about any Linux Distro you can name (Mint, Nabora, PopOS, etc) and just install the standard Linux Steam Client and run the new Big Picture Mode from there.

If you want to install the Official SteamOS 3 for PC, you're going to have to wait otherwise.
