How to mount ISO files: complete guide for PC, Mac, smartphone and USB

An ISO file is an exact copy of a CD or DVD contained in a single file. This format is useful for distributing software, operating systems, or other data in a compact and easily transferable way via the Internet. ISO files are particularly useful for those who need to install or test software without having to use physical media such as CDs or DVDs.

This guide is aimed at technical users who want to mount ISO files on various devices, including Windows PCs, Macs, smartphones, tablets, and virtual machines. Mounting an ISO file allows you to access the files contained within it as if they were on a physical disk, facilitating installation or data extraction.

By following this guide, you will learn to mount ISO files using tools integrated into operating systems or third-party programs, depending on the device used. The procedures described are simple and accessible to everyone, even those who are not computer experts.

By following this guide, you will learn to connect an ISO image to the virtual optical drive of a virtual machine using VirtualBox.

• Download and install VirtualBox by Oracle.
• Configure the virtual machine to connect the ISO image to the virtual optical drive.

VERIFICATION AND TROUBLESHOOTING: How to Test if It Works and What to Do if It Fails

After mounting the ISO file, verify that the content is accessible and that the virtual drive has been created correctly. Here's how to proceed:

On Windows

• Mounting Verification: Open File Explorer and check that the virtual drive appears in the Devices and drives section. It should be labeled as DVD-ROM with the volume name.
• File Access: Click on the virtual drive and verify that the files contained in the ISO file are visible and accessible.
• Unmounting: If the virtual drive does not unmount correctly, restart the computer and try again.

On Mac

On Windows 7 with WinCDEmu

• Mounting Verification: Check that the virtual drive appears in File Explorer with the label CD Drive.

On Smartphone and Tablet

• Extraction Verification: Open the app used to extract the files and check that the files contained in the ISO file are visible and accessible.
• Compatibility Issues: If the app cannot read the ISO file, try another app compatible with ISO files.

In Virtual Machine

• Mounting Verification: Check that the ISO image is correctly connected to the virtual optical drive of the virtual machine.
• Compatibility Issues: If the virtual machine does not recognize the ISO file, verify that the virtualization software is updated to the latest version.

Writing to USB

• Verification of Bootable USB Creation: Insert the USB drive into the computer and verify that it is recognized as bootable.
• Boot Issues: If the computer does not boot from the USB drive, check the BIOS/UEFI settings to ensure that USB boot is enabled.
