File damged or broken after conversion.Step 4: Once the ISO file has been created, you can use a burning tool to create the bootable USB drive. Hdiutil convert /path/sourceimagefile.dmg -format UDTO -o /path/targetmage.iso Step 3: Use the following command to convert the DMG file to ISO: If it is in a subfolder, type "cd \subfolder", and so on. For example, if your disk image is in D: and Command Prompt is currently in "C:", then type "d:" (no quotes) and press Enter. You can do this by using the "cd" command followed by the file path, then pressing Enter. Step 2: In the command interface, go to the directory in which the DMG file is saved. Step 1: Open Command Prompt by typing cmd in the Run windows and hitting Enter. If you follow the steps below, you can convert any DMG file to ISO and then create a bootable USB using the converted file. Don't be intimidated by the non-GUI environment even if you don't have any experience. The easy way to do this is to use Command Prompt. Why? A lot of easier to find an app for making a bootable USB from ISO file. Since Windows doesn't offer native support for DMG files, you can first convert the file to ISO.
Thank you and hope all have fun with this barrier being overcome.Part 1: Convert DMG to ISO and Make Bootable USB from ISO You don't even have to delete the DMG, just add on to it the ".iso" and it will be recognized as a ISO file. I hope this helps some macOS users and others get better access to using the software files as is with a simple change of extension. Yes, it gives the warning that this could make the file become unstable, but its not messed up on me for the past 15-20 installs testing out this theory and winning the deal with success. I feel this is something that every user of VirtualBox should know so they aren't searching for ISO files of MacOS when they can just change the file extension to "iso" and it will boot up and install the application. So I then took like 8 different DMG files and just changed the file extension from DMG to ISO and they all booted up and loaded in VirtualBox. Well today I got to thinking more into it that a DMG file is another format of a disk image, so I didn't change the DMG but added to it ".iso" and connected it to the VirtualBox, and wouldn't you know it, it booted up. Well I have been using AnyBurn to convert the DMG files from MacOS to IMG then changing the extension to ISO. It warns you that the file could become unstable, but when I done that, it worked. I came across a techs stand point that the images are so close to the same that you could probably get by with just changing the file extension from IMG to ISO. I done some checking about converting an IMG to ISO to use on VirtualBox.
As I have been really getting into playing on VirtualBox more and more, I have came across some issues with using Linux mint to get disk copies that are in IMG format.
