How to install steamos in virtualbox

This step by step guide will easily let you install Steam OS beta on virtualbox. However, please be aware that a VM will not exhibit the same performance level as a bare installation. Gaming (of any type) is likely to be awful. It’s fine to try out the install though and have a good overview of the OS. You could try out how to setup a dual boot on your machine for example.

You get a zip file which you need to unzip to then create an iso.

To create the iso from the SteamOSInstaller folder, run:

The above commands believes you have the SteamOSInstaller you extracted from the zip in the /tmp folder

Then in VirtualBox, create the New button to create a new VM.

Name it Steam OS for example
Choose Type = Linux and Version = Debian (64 bit)
Select 2048Mb of RAM
Create a virtual hard disk with 500Gb

Now go in the settings of this VM, then Storage and in Controller IDE, click on Empty, click on the little CD, click Choose a virtual CD/DVD disk file. and select the SteamOSInstaller.iso created before.

Now click on System in the left menu and tick the box Enable EFI.

Finally, click on Display in the left menu and tick the box for 3D Acceleration and choose the amount of memory you want to allocate.

You can now start the VM, the installer will start and you can choose Automated Install (WILL ERASE DISK)

Now, drink a cup of tea while the install is being done.

When install is finished, you will be asked to click a Continue button to reboot, you should then see the grub bootloader with Steam OS entry, select the entry with recovery mode.

You are now on a shell, you need to uninstall nvidia packages, so you run:

If you fancy trying out StemOS without the need to invest on expensive hardware’s, then this post would guide you on how to install SteamOS on a Virtual Machine using Oracle VirtualBox. I am testingВ this on VirtualBox version 4.3.10. The performance on a Virtual Machine cannot be compared to installing on an actual physical machine but using a VM would suffice for test purposes.

Heads Up: You must exercise patience if you are to successfully install SteamOS on VirtualBox рџ™‚

Step 1: Download latest VirtualBox and Install

[button link=”” style=”download” color=”primary”]Download VirtualBox Manager[/button]

Step 2: Download SteamOS ISO

– An ISO file had been made available for ease of installation

Step 3: Create new Virtual Machine

– Create a New Virtual Machine and use recommended settings below

– Under new VM settings, click on System > Motherboard and enable ‘Enable EFI (special OSes only)’

– Under Display > Video, set Video Memory to max (128); check the box ‘Enable 3D Acceleration’

– Under Storage, click the disk icon and choose the downloaded ISO

– Set your Network to Bridged Adapter

Step 4: Install SteamOS

– Start the VM,В choose Automated install and press Enter

– Wait until is completed. System will auto reboot

– Choose (recovery Mode) immediately and press Enter

– This should load into Linux terminal

Step 5: Remove NVIDIA Package

– Regenerate a new configuration file

Step 6:В Install VirtualBox Guest Additions

– Click on Devices > Insert Guest Additions CD image. Then mount the CD-ROM, Install and Reboot VM

– System will reboot into GNU GRUB screen. Select the first option and Enter

– When SteamOS desktop appears, SteamВ Update would start immediately

– After the update, for some reasons, the Partclone ran. After this bit completes, restart the VM

Step 7: Final Config

Note: At first when the system rebooted, I changed the directory to ‘FS0:’ but noticed that when I list the directory, it was showing contents of the VirtualBox Guest Additions tool. So to fix this, I had to shutdown the VM, under settings I unmounted the CD then reboot again

– On reboot, you will be presented with this screen. At the console, first type ‘FS0:‘ as Fox, Sugar, Zero, colon

– Then type ‘efisteamosgrubx64.efi‘. Enter and wait for system to reboot

– If everything goes well, you should have your steam desktop with you. You can launch Steam by double-clicking on the Steam icon


For those whose screen might be showing blank as I experienced, you need to ensure that your machine meets the supported hardware requirements. In my case, I have an Intel graphics cardВ which isn’t supported yetВ рџ™Ѓ

SteamOS Hardware Requirement

  • Intel or AMD 64-bit capable processor
  • 4GB or more memory
  • 500GB or larger disk
  • NVIDIA graphics card ( AMD and Intel graphics support coming soon )
  • UEFI boot support
  • USB port for installation

If you fancy loading to the desktop:

  • Press Ctrl+Alt+F1
  • From console screen, enter username as ‘desktop’ with no password
  • Next type ‘Startx’ to start the Desktop
  • If you want to go further, open a terminal and type ‘steam’ to load steam

I will acquire an Nvidia PCI graphics card and try this on a desktop machine and update this post

In this article i am GOING to teach you how to install New Steam OS on Windows without removing or PARTITION your WINDOWS using th Oracle Virtual Box Step by Step

Below is the Video Tutorial for how the installation of Steam os on Windows and Below that all the codes and instruction written in step by step

December 17, 2013

I presume that you are here because you know what SteamOS is and you want to try run it as Virtual Machine in VMware Workstation on Windows. In few steps, I will show you how to do it.

Downloading and creating SteamOS ISO

In order to download SteamOS files simply click the following link.

After you download files, extract them into a folder. Now we need to create ISO file from extracted files. I used CDBurnerXP to do it.

Here is step by step guide.

  1. Select Data Disc
  2. Drag SteamOS extracted files into compilation How to install steamos in virtualbox
  3. Go to Disk -> Boot Options. Select Make disc bootable and set following settings.
  • Select path to boot image: SteamOSInstallerbootgrubbootx64.efi
  • Emulation type: Hard Disk
  • Platform: x86-64
    How to install steamos in virtualbox
  1. Change disc file system. Click Data -> Change File System and select ISO9660/ Joliet.
  2. Click OK and go to File -> Save Compilation as ISO file and give desired ISO name.

Installing SteamOS as Virtual Machine in VMware Workstation

When ISO is completed create empty custom Virtual Machine with following settings:

  • Hardware Compatibility – VMware Workstation 10
  • Install operating system later
  • Guest Operating System – Linux, Debian 7 64-bit
  • 1vCPU, 4GB RAM, 20GB Hard Disk
  • Edit Virtual Machine configuration file (vmx) and add entry firmware = “efi”

After you will mount ISO in Virtual Machine CD-ROM power it on.

Installation of SteamOS step by step.

  1. Select Automated Install.

  2. Wait for the installer – you don’t really have to do much there. How to install steamos in virtualbox
  3. After installation reboot it. How to install steamos in virtualbox

Configuring SteamOS for full gaming experience

After installation, there are several steps to make SteamOS fully work in VMware Workstation. Here are steps which I did to play games using SteamOS.

  1. Change root password In order to change the root password from login screen select Default Xsession. As username enter desktop with password desktop. Start Terminal and type sudo passwd root. Provide credentials for the desktop user and change the root password. How to install steamos in virtualbox
  2. Install VMware Tools

Click on SteamOS Virtual Machine and select Install VMware Tools.

  1. Installation is done in several steps:
  • Login as root
  • Start Terminal
  • copy VMware Tools tar file to home directory – cp /media/cdrom/VMwareTools* /home/steam/
  • extract files using command tar -zxf VMwareTools*
  • enter directory vmware-tools-distrib
  • as root execute installation script – ./
  • safely you can go for standard settings – just hit enter everywhere
  • restart SteamOS Virtual Machine so all VMware Tools drivers are loaded
  • Change Sound Card in the system

After VMware Tools are installed login to Default Xsession as a desktop as root. Go to System Settings and then click Sound. Go to Hardware tab and change Analog Stereo Duplex to Analog Stereo Output, turn on sound and test speakers.

Play it!

Finally, after some time you can test new shiny SteamOS. On login screen enter default SteamOS username steam and password steam and select Gnome as graphical user interface.

After login you will see Steam icon. Double click it and you will see Steam License Agreement.

How to install steamos in virtualbox

SteamOS has finally dropped in all its beta glory. While 300 lucky preview testers scored Steam hardware as well, most of us have to install it on our own machines if we want to try it out. Here’s how to do that.

Before we begin, there are some very important caveats:

  • This will wipe your machine. Due to the way Valve has distributed this image, you cannot partition a hard drive or dual boot it with your existing set up. This is a recovery image and your partition table will be wiped clean if you attempt to install it on the same hard drive. If you want to play around with it in a non-destructive manner, you can try it in a virtual machine. Once you have SteamOS installed, you can create a new Windows partition, but this will wipe your existing setup.
  • This may wipe your secondary hard drives, too. The basic method is not optimised for installing on systems with multiple drives. Depending on how your boot tables are set up, you might inadvertently lose data on your other drives as well. Keep safe and remove all hard drives except the one you want to install SteamOS on.
  • You’ll need an NVIDIA graphics card. Sorry AMD users. Support is reportedly coming in the future, but for now if you don’t have an NVIDIA graphics card, you’ll have to sit this one out.

What You’ll Need

How to install steamos in virtualbox

Before you get started, here’s what you’ll need to download and/or collect:

  • The SteamOS Installer (Here’s an unofficial torrent)
  • A 4GB or larger USB stick
  • A Motherboard with UEFI support

There are two main ways to install SteamOS, and the method you choose will determine which download you need. The easiest method involves flashing a recovery disc image and that download is about 2.4GB (called “” at the link above). The slightly more complicated method which has all the fun expert buttons is about 960MB and labelled “”.

Method #1: The Easy Way

How to install steamos in virtualbox

The simplest method to get SteamOS up and running is to install the recovery image. Again, as a reminder, this method will completely erase your entire hard drive regardless of partitioning. As long as you’re prepared for that, here’s what to do:

  1. Format the USB stick to FAT32. Name it “SYSRESTORE”.
  2. Unzip and place its contents on the USB drive.
  3. Boot your machine from the USB stick.
  4. While booting, select the UEFI entry from the boot menu.
  5. Select “Restore Entire Disk”.

This method will result in a complete, ready-to-use SteamOS installation being created on your machine. If you want to dual boot SteamOS with a Windows installation, you can set that up now. While the SteamOS release is based on Debian, our guide to dual booting Windows and Ubuntu can at least help point you in the right direction.

Method #2: The Advanced, Flexible Way

How to install steamos in virtualbox

If you’re feeling more adventurous (or want to minimise how much you have to download directly from Steam), you can use the secondary method. There are two primary differences between this method and the previous one. For starters, the download is significantly smaller. Part of the reason for this is because once you install the OS, you still need to download Steam. What you’re installing is mostly just a customised version of Debian.

More importantly, this method has an Expert Install mode. You can use this method to tweak a few settings. That being said, if you’re not extremely experienced with Linux distributions and installs, you probably shouldn’t mess with this.

To install SteamOS via this method, follow these steps:

  1. Unzip the smaller, file to your USB stick.
  2. Boot your machine from the USB stick.
  3. Select the UEFI entry from the boot menu.
  4. Select “Automated Install”.
  5. Once the install is finished, boot into the OS. You will be faced with a login screen. There is a default account with both the username and password are “steam”. Log in with these credentials.
  6. Double-click the Steam icon on the desktop to download and install Steam.
  7. After this, you can log in to SteamOS via the login menu you used in step 5 (select “SteamOS” via the dropdown box) with the same credentials.

If you’d like to maintain the Debian installation and log in to SteamOS only when you need it, you can simply end here. However, if you’d like to commit all the way, follow Valve’s instructions here from step 8 in the final section onward to make the final customisation tweaks so that the partition is 100 per cent Steam.

Method #2.5: A Note On Virtualisation

How to install steamos in virtualbox

OK, so you’ve come this far and you’re still not sure you want to take the plunge. That’s fair. SteamOS is still a beta and it requires a fairly big commitment. If you’d still like to give it a shot, you can install SteamOS in VirtualBox. If you don’t already have VirtualBox set up, our guide here will get you started.

The process for creating a virtualised SteamOS machine is a bit more complicated than the installs above, but this guide can walk you through the process fairly well. It builds on method #2 above, though instead of a USB installation, you’ll create an ISO out of the installer. Keep in mind, though, that running SteamOS inside a virtual machine will probably result in some pretty poor performance and almost certainly won’t be good for real gaming. This method is probably best for the idly curious who would just like to fiddle.

Where is the source for SteamOS?

What are the hardware requirements for SteamOS?

  • Intel or AMD 64-bit capable processor
  • 4GB or more memory
  • 500GB or larger disk
  • NVIDIA graphics card (AMD and Intel graphics support coming soon)
  • UEFI boot support
  • USB port for installation

How do I install SteamOS?


Both of the following methods will erase everything on the target machine. Please ensure you are prepared to remove all content before proceeding.

Currently, there are two different install methods for SteamOS.

Method 1:

The easiest method is an image-based install using CloneZilla. You will need to create a SteamOS System Restore USB stick to perform this install. The image provided here requires at least a 1TB disk.

  • Format a 4GB or larger USB stick. Use SYSRESTORE as the partition name
  • Unzip the contents of to this USB stick to create the System Restore USB stick
  • Put the System Restore USB stick in your target machine. Boot your machine and tell the BIOS to boot off the stick. (usually something like F8, F11 or F12 will bring up the BIOS boot menu).
  • Make sure you select the UEFI entry, it may look something like UEFI: Patriot Memory PMAP
  • Select Restore Entire Disk from the GRUB menu.
  • System Restore will proceed automatically. When it is complete it will reboot into your freshly re-imaged SteamOS

Method 2:

The second method is based on the Debian Installer. It requires multiple configuration steps:

Eric Hansen


Valve brought on a heavy load in customizing Debian Wheezy (7.1) to create their own distro. Their vision with this was to create a centralized gaming center that would house everyone’s Steam games and people would be able to share them across their home. While currently it only works with Linux games, they aren’t leaving Windows behind.

This tutorial series will cover the SteamOS and all of its gaming fun. The screenshots will be provided via VirtualBox (apparently in 4.0+ you can take screenshots AND record video? Its been way too long for me), so the quality should be pretty up there.

Not a fan of this, but since its a distro I’m not familiar with, I’m going into this as blind as you probably are. I have some ideas what to expect as I’ve seen prior screenshots, but for the most part you’ll be learning along with me.

With that said, if something doesn’t work for you please feel free to still post about it. One distro is virtually the same as another.

What We Need
I started out by having to make the ISO myself. However, I discovered after the fact there’s an ISO pre-made that Steam’s download page doesn’t like to disclose. This can be found at (I highly recommend this instead of making one yourself as you then have to do some weird jinjitsu work to boot).

If you’re not wanting to install this on an actual machine, you will also need VirtualBox (any other virtualization software is untested by me). I’m using 4.3.6 for this but I don’t see there being any issues as long as its 4.0 or higher.

When creating your virtual machine, its advisable to allocate half your memory (for me its 4GB) to it. If you want to REALLY use the OS for its intentions, I’d recommend installing it on a physical machine. But, for this, it will be fine. Also, set the video memory to 128MB and enable 3D acceleration. It helps. Lastly, enable EFI mode, or else the ISO won’t boot from previous experiences.

Getting Started – Booting Up With the ISO and Installing
So you have the ISO downloaded and attached to your virtual machine, now what? Boot up!

You’ll come up with a screen that looks like this:

Choose “Automated install”. SteamOS is intended to be the only OS placed (think of it as a media hub of sorts). If you want to try the expert install I wouldn’t mind some feedback on it. Though, its most likely the interactive installer instead of doing everything for you.

This will do everything for you, so you won’t have to click through a billion menus and such.

It took me a good 20 minutes or so with the automated install.

Fresh Install – Booting Up Again (follow if you’re doing this in VirtualBox only)
Now that we have the OS installed, you’ll be presented with this screen:

Pretty cool, huh? Well, we still have something else to do.

I wish I knew why Valve figured it was good to assume everyone uses nVidia, but if you boot up right away then your system will hang. Instead, at the boot menu we need to go into rescue mode, purge the nVidia drivers and install the VirtualBox additions.

Once you’re in rescue mode (terminal/command prompt), enter this:

Nothing will output, as it just writes new configuration files to /etc/X11.

Installing the additions requires going to Devices->Install Guest Additions CD image then typing:

Reboot again by typing the “reboot” command and choose the first item in GRUB.

Our First Graphical Boot!
Regardless if the way you’re installing, you should now be presented with a Gnome 3 environment and Steam updating. I did have a screenshot for this but for some reason it black screened.

After This
Currently, I’m not having much luck in getting it to boot up again properly.

What happens for me is that if it does boot past the UEFI loader, it flashes the boot logo then goes to a black screen. However, I’m not sure if this is my own doing or what.

Let me know if you had better experiences with this, and I’ll be trying to fix this issue on my end as well.

Stephenson’s Rocket – a modified SteamOS installer, with wider support for more complex computers

The Artist Formerly Known As Ye Olde SteamOSe

SteamOS is now shipping, in beta form at least, and it’s all cool and stuff.

Valve have now integrated most of the improvements from Ye Olde SteamOSe, such as BIOS and DVD support, into their installer. You can download it from here.

Stephenson’s Rocket replaces the Ye Olde SteamOSe project by building back on Valve’s installer with bug fixes and improvements – especially hardware support.

This kind of collaborative development demonstrates the power of Open Source – and remember, you can contribute to Stephenson’s Rocket too! Click “View on GitHub” at the top of the screen to get started, and watch the development tutorial video linked below!

  • SteamOS monopolizes drives. Stephenson’s Rocket can resize NTFS partitions.
  • SteamOS only supports basic partitions. Stephenson’s Rocket supports LVM and RAID.
  • SteamOS requires a Radeon 5000 or newer for ATI users. Stephenson’s Rocket will use the Open Source driver instead on older cards.
  • SteamOS requires a Geforce 400 or newer for NVIDIA users. Stephenson’s Rocket will use the legacy 340 series driver instead on older cards.
  • SteamOS is only updated when Valve have time. Stephenson’s Rocket comes with the tools to update it with the latest stuff yourself!
  • Support NVIDIA cards no longer supported in current nvidia-glx driver.

A DVD image is always available at

To get started, download the torrent.

Otherwise, clone this repo, and run ./ .

Installing from a DVD

Just burn the ISO to a blank DVD from your favourite tool, and boot it.

Installing from USB (Mac)

Open a Terminal window from the Utilities section of Applications.

Type diskutil list to get a list of devices – one of them will be your USB stick (e.g. /dev/disk2 ). Follow the Linux instructions below but change:

  • /dev/sdX to /dev/rdiskX
  • bs=1M to bs=1m

Installing from USB (Linux)

Plug in the USB stick and run dmesg ; look for a line similar to this:

In this case, sdc is the device name for the USB stick you just inserted. Now we put the installer on the stick, as root (e.g. use sudo ) run

sdX should be the USB stick device from the information you received from dmesg . Be sure to use sdX, not sdX1 or sdX2. Then boot into the stick.

Installing from USB (Windows)

Download Win32 Disk Imager and use it to copy the .iso to your USB stick (1GB minimum size).

Once the installer is up.

Pick the “Automatic Install” option to wipe the first hard disk in your system and install SteamOS to it.

For more sophisticated booting – e.g. dual-boot or custom partition sizes – select the “Expert” option. Use of this mode is documented in the support video here.

Beyond that, just follow Valve’s instructions from their site – Stephenson’s Rocket should behave exactly like the real SteamOS, except it works on more systems

Before you generate a new image you need to ensure that your pull is up to date as things change quickly:

  • git pull in the steamos-installer directory will ensure you have the latest code.
  • ./ -d will ensure that you download the latest SteamOSDVD.iso

Known issues and workarounds

  • 3D support is broken in Big Picture Mode itself and in 32-bit games in VirtualBox. This is a flaw in the Debian packaging of the VirtualBox guest drivers.
  • Crashes and strange behaviours on NVIDIA Maxwell cards with certain OpenGL games and applications. This requires an update to the lastest driver to fix, which has not yet been packaged for APT.
