Part 3: Convert DMG to ISO and Burn ISO to USB

In certain instances, you may want to use a Windows computer instead of a Mac, which means you won't have the disk utility. Besides, Windows can't natively handle DMG files, so you will need to convert it into an ISO disk image that Windows can work with. Follow the steps below to do this.

Step 1: Download the DMG file and then convert it to ISO using a free online conversion service like YouConvertIt.

Step 2: Once you do this, you can use another utility like ISO Editor to burn the ISO file to a USB drive.

Pros:

  • More options available for burning ISO image.

Cons:

  • Take much more time.
  • USB not bootable.

Similarly, when you use a Windows system, converting DMG to ISO could corrupt the file, making it unusable once you convert it back to DMG. That's why we recommended YouConvertIt for that. Based on all these factors, choose the method that will work best for your specific situation.
