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.
- 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.
-
Select "Create image file from disc": Launch ImgBurn and choose this option.
-
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.
- Choose ISO Format: Use the "Save as type" dropdown to select "ISO". Note that ImgBurn may use BIN format if multiple tracks are detected.
- 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.
- 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".
-
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.
-
Unmount the Disc: Open Terminal. Use the
mount
command to identify the disc's mount point. Unmount it usingsudo umount [mount point]
(e.g.,sudo umount /dev/sr0
). -
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.
