How to Create ISO Files From Discs on Windows, Mac, and Linux

This guide explains how to create ISO files from physical media (CDs, DVDs, Blu-rays) on Windows, macOS, and Linux. Creating ISO images is a valuable way to preserve the contents of physical discs, which are prone to deterioration over time.

Creating ISO Files on Windows

Windows lacks built-in ISO creation tools, requiring a third-party application. While many free tools exist, many haven't been updated in years. This guide uses ImgBurn, a free and reliable option.

1. Download and Install ImgBurn: Download ImgBurn from its official website, ensuring the download source is legitimate to avoid malware. Install the application like any other Windows program.

2. Select "Create image file from disc": Launch ImgBurn and choose this option.

3. Select Source and Destination: Insert the disc. Select the correct optical drive (ImgBurn will also list virtual drives if present). Choose the save location for your ISO file.

4. Choose ISO Format: Use the "Save as type" dropdown to select "ISO". Note that ImgBurn may use BIN format if multiple tracks are detected.

5. Start the process: Click "Read" to begin creating the ISO. ImgBurn will display progress and play a sound upon completion.

Creating ISO Files on macOS

macOS uses a two-step process: creating a CDR image, then converting it to ISO.

1. Create a CDR Image: Insert the disc. Open Disk Utility (Applications > Utilities). Select the disc volume (not the drive name). Go to File > New Image > New Image From [Volume Name]. Choose a save location, select "CD/DVD master" format, and leave encryption as "none".

2. Convert CDR to ISO: Open Terminal. Navigate to the CDR file's location using the cd command (e.g., cd /Downloads/ISO). Use this command to convert: hdiutil makehybrid -iso -joliet -o filename.iso filename.cdr (replace filenames accordingly).

Creating ISO Files on Linux (Ubuntu example)

Linux uses command-line tools.

1. Unmount the Disc: Open Terminal. Use the mount command to identify the disc's mount point. Unmount it using sudo umount [mount point] (e.g., sudo umount /dev/sr0).

2. Create the ISO: Use this command: sudo dd if=/dev/sr0 of=/tmp/CARMAGEDDON.iso (replace /dev/sr0 with your disc's location and /tmp/CARMAGEDDON.iso with the desired path and filename).

Finding an Optical Drive: Since optical drives are uncommon in modern computers, you might need an external USB drive or access one at a library.
