What is Steam Deck?

A robust portable gaming device running a customized SteamOS based on Linux, the Steam Deck was created by Valve Corporation.

The Steam Deck is a versatile portable computer with powerful hardware that can handle a wide range of applications, including mounting ISO files. It’s not only used for gaming, though.

Switching to Desktop Mode on Steam Deck

Go to Desktop Mode first if you want to mount an ISO file on your Steam Deck. In this mode, the Steam Deck is turned into a regular Linux desktop, complete with all the tools and applications you need to mount ISOs.

Accessing Desktop Mode

Press and hold the Steam Deck’s power button to enter Desktop Mode. After that, a menu with multiple choices will show up. To go back to the Linux desktop interface from the game interface, click “Switch to Desktop Mode.”

Navigating the Desktop Interface

When you switch to Desktop Mode, you’ll see the standard desktop layout with the taskbar down the middle. By providing the standard file management and application installation tools found on any Linux-based computer, this interface makes it easy to navigate and work with the system.

Installing Required Software

There is software that is required in order to mount an ISO file. There are a number of ISO mounting tools available for Linux, but PowerISO is among the most widely used.

Opening Discover Software Center

You can get most of SteamOS’s apps from the Discover Software Center. Locate and install ISO mounting software by opening it from the taskbar.

Searching for PowerISO

Find an ISO mounting tool that works with Linux, like PowerISO, by using the search bar in the Discover Software Center. To add it to your system, click “Install” once you find it.

Installing the Software

Finish installing it by following the on-screen prompts. You will be able to easily mount ISO files after the software is installed.

Mounting an ISO File

You can mount your ISO file after you have installed the required software. To get the ISO’s contents onto your Steam Deck, you just need to follow these easy steps.

Locating Your ISO File

Find the folder containing your ISO file using the file manager available in Desktop Mode. The mounting process will go more smoothly if you are aware of the precise location.

Mounting the ISO

To open or mount the ISO file with the installed software, right-click on it and choose the option. The ISO’s contents will be accessible just like any other disc because the software will create a virtual drive.

Accessing the Contents

You can install, transfer files, or browse the ISO once it is mounted. This feature comes in handy when you need to install software or games straight from an ISO file.

Unmounting the ISO File

It is critical to unmount the ISO file after using it to release system resources. To unmount an ISO file, find the virtual drive it created and right-click on it. Then, choose the “Unmount” option. Doing so will securely remove the ISO file from your computer.

Ensuring System Integrity

To avoid data loss and maintain system stability, unmount the ISO file. For best performance, always unmount ISO files when not in use.

Common Issues and Troubleshooting

Although mounting an ISO on the Steam Deck is usually a breeze, you may run into a few typical problems. Find solutions to these issues and learn how to troubleshoot in this section.

Software Compatibility Issues

Occasionally, compatibility issues might cause the ISO mounting software to not function properly. Make sure you’re using a version of the program that’s compatible with Linux.

ISO File Corruption

It might not mount properly if the ISO file is damaged. It is important to check the ISO file’s source or use a file integrity tool to ensure its integrity before trying to mount it.

Permission Errors

On occasion, Linux systems may limit who can access specific folders or files. Verify that you have the appropriate administrative privileges or change the file permissions if you continue to encounter permission errors.
