If you want to convert DMG to ISO, it's good to learn a little about disk image file types and what they're meant for. Essentially, a disk image is a snapshot of the content on a DVD, CD, BRD or even a hard drive. It could be just a set of media files, but it can also contain software installation files. In the second case, the disk image will also need to contain boot information in order to boot from the media.
Specifically, DMG is what Apple uses for the macOS environment, while ISO is more widely used in Windows-based and Linux environment. At times, you may need to convert DMG to ISO so you can mount it as a virtual drive on a Windows machine to extract the contents, view them or burn them to create bootable media. The process to convert DMG to ISO is different based on which operating system you're using for the conversion. This article shows you how to convert DMG files to ISO files on Windows, Mac and Linux.
Method 1: How to Convert DMG to ISO on Windows 10 (DMG2IMG)
DMG2IMG is a software utility that converts DMG files into Apple's older IMG format as well as the universally used ISO format. The process is simple, but it requires some command line work. The steps to use DMG2IMG to convert DMG to ISO have been detailed below:
Step 1. Download and install DMG2IMG on your Windows computer. Once the installation is done, open File Explorer and go to the location where you downloaded the application.
Step 2. Right-click on the folder where the software has been downloaded, and select 'Open command window here…' to launch Command Prompt.
Step 3. In Command Prompt, execute the following command (click Enter after typing in the command):
dmg2img 'C:UsersSample UserDesktopsample.dmg' 'C:UsersSample UserDocumentsConvertedRandom.iso'
Step 4. Please note that the double-quotes are required only if you have a space in your file path. In this example, there's a space between Sample and User, so the quotes are needed. If there are no spaces, you can do away with the quotes.
