If you want to install the SteamOS along with Windows 10, this post is worth reading. Here, MiniTool offers you a full Steam OS installation guide. You will learn the basic information, hardware requirements, and detailed install steps from the post.

What Is SteamOS

The SteamOS, a Linux-based operating system released in 2013, is built based on Debian 8 and offers an environment similar to that of a console. It is built for playing video games in the living room as no keyboards or mice are required to interact with the OS. Besides, it makes your PC behave in a console-esque manner.

Being an open Linux platform, SteamOS leaves you in full control. It means that you can take charge of your system and install new software or content as you like. With this system, you can transform your current computer into a Steam Machine so that you don’t have to get a SteamOS computer.

Tip: SteamOS computers from manufacturers like Alienware, Falcon Northwest, and Origin PC, are known as Steam Machines too.

Hardware Requirements for Steam OS Installation

Before getting the Steam OS installation, you need to know the hardware requirements of this system and then check if your PC meets the specs. Actually, most mid to high-end computers can run SteamOS without issues.

  • Processor: Intel or AMD 64-bit capable processor
  • GPU: Nvidia graphics card, AMD graphics card (Radeon 8500 and later), or Intel graphics
  • Memory: 4GB or above
  • Hard Drive: 500GB
  • UEFI boot support

In addition to the above system requirements, you should also prepare an Ethernet connection, a USB game controller, and a USB flash drive with at least 4GB of space.

1. The SteamOS is still in beta, which means that parts of the operating system are not 100% functional. There are some bugs with the SteamOS that need to be worked out.
2. The SteamOS installation operation will erase your entire hard drive, so back up your important data to external drives in advance.

There are two options for the Steam OS installation. The first one is to completely transform the current system into SteamOS, while the second one is to dual boot SteamOS and Windows 10 (or other systems). Pick one option based on your needs.

Option 1: Transform the Current System into SteamOS

Steam OS ISO Download

To download SteamOS ISO, you need to follow these steps.

Make a Steam OS Bootable USB

After getting the SteamOS ISO download, you need to make a Steam OS bootable USB drive. For doing that, connect a blank USB flash drive to your computer. The USB drive should be in FAT32 format with the MBR partition table.

To meet the requirement, you need to format your USB to FAT32 on computer. You can do that with Windows built-in utilities like File Explorer, Command Prompt, and Disk Management, or use third-party USB formatter like MiniTool Partition Wizard. Then name the USB device as BACKUP.

Check if the partition table of the USB flash drive is MBR. If not, you need to convert it to MBR manually. Here are detailed steps for that.

Step 1: Right-click on the Windows icon and tap Disk Management.

Step 2: Right-click on the USB drive and click Properties.

click properties

Step 3: Navigate to the Volumes tab in the Properties window and check partition style. Then click OK to exit the window.

Warning: You are required to initialize your hard drive especially the new one after you connect it to your computer. Otherwise, you will receive the “You must initialize a disk before Logical Disk Manager can access it” error message.

After that, unzip the downloaded SteamOS ISO file to your USB drive. Then unplug the Steam OS bootable USB drive and plug it into the target computer.

Note: Since SteamOS only supports UEFI, you need to ensure that the device is UEFI setup. Otherwise, the Steam OS bootable USB drive can’t be recognized.

Option 2: Dual Boot SteamOS and Windows 10

If you just want to try the SteamOS and don’t want to remove the current system, dual-boot is a good choice. There are many dual-boot cases. For instance, you can boot these systems at the same time.

Create a Partition for the SteamOS

To dual boot SteamOS and Windows 10, you need to get enough space at first. Besides, you’d better create a new partition to hold the SteamOS in order to not affect the current system. Here, you should create a partition with 500GB space or more. Hence, your hard drive should have at least 1TB of space.

If the present unallocated space is less than 500GB, you need to shrink partitions to obtain space. The Move/Resize Partition feature of MiniTool Partition Wizard can help you do that with ease. Besides, it allows you to put unallocated space together by moving the locations of the partition. Here’s the full guide for you.

Step 1: Download MiniTool Partition Wizard by clicking the button below and then install it.

Step 2: Right-click on the partition that you would like to shrink and click Move/Resize.

click move or resize

Step 3: In the pop-up window, drag the arrow icon to resize the partition and change the location of the partition by moving the partition block. After that, click OK to save changes.

Tip: As the present unallocated space is 324GB, you need at least 176GB of free space. To quickly get the needed unallocated space, you can directly type the exact number behind the Unallocated Space Before section.

resize the partition

Step 4: Here, you need to change the location of partition L and unallocated space behind it. Similarly, right-click on L partition and tap Move/Resize. Drag the partition block to move rightward and then click OK. Then you will see the unallocated space is merged together.

change the location of partition

Step 5: Highlight the unallocated space and click Create Partition in the action panel.
