In order to convert the dmg to iso you need: 1) Convert the dmg to img using dmg2img. You can install it using: sudo apt-get install dmg2img. Then (if your dmg is named image.dmg in the current folder): dmg2img image.dmg image.img. 2) To mount the img. Mkdir /media/image. Sudo modprobe hfsplus. Sudo mount -t hfsplus -o loop image.img /media/image. To boot from this media, hold down the Option key and fire up your Mac. Convert DMG to ISO and Create macOS Boot USB from Windows. Since ISO is a better format for Windows, you can also convert the DMG to the ISO format and then use the ISO disk image to create the bootable USB. This guide covers the verbatim copying of a DMG image to a USB thumb drive using only Linux (no need to find a Mac). If the DMG was intended to be bootable then the resulting USB will be bootable. Convert to ISO. Linux doesn’t much care for DMG files. Sure, it’ll play nice with them.
A DMG disk image file is Apple's container format for capturing entire drives or disks, similar to ISO for other platforms like Windows. It consists of data blocks that represent a physical disc. If you're on a Windows machine, you're limited in what you can do with DMG files. That's why you need third-party utilities to create a bootable DVD from DMG on Windows. This article explains two different methods to burn DMG files to amake bootable macOS installation DVD in Windows.
Method 1: How to Create Bootable DVD from DMG (Command Prompt)
This approach utilizes a tool called DMG2IMG, which converts DMG file into ISO, the universally more compatible archive format. This ISO file is then burned using a command line execution in Command Prompt. You don't really need any experience with disk images or command line work, but it will certainly help should something go wrong. If you're not comfortable with any of this, you can skip to Method 2, which showcases a powerful but user-friendly tool that does it all for you. But first, let's see how the Command Prompt method of creating a bootable DVD from DMG works.
Note: The older version of DMG2IMG is called DMG2ISO. Although the download is available in the link provided in Step 1 below, it is recommended that you use DMG2IMG instead. The utility has the ability to convert DMG into both ISO and IMG, based on your needs.
Step 1. Install DMG2IMG on a Windows PC after downloading the zipped win32 binary from this website. Unzip the file and run the .exe to install the program. You can also download DMG2ISO, but DMG2IMG is the recommended software to use.
Step 2. Open Command Prompt on your PC and execute the following command to convert your DMG into ISO. Be sure to change the file names as appropriate, and include the whole file path from the main directory:
dmg2img.exe c:downloadsexample.dmg c:downloadsexampleconverted.iso
dmg2img.exe c:downloadsexample.dmg c:downloadsexampleconverted.iso
Step 3. Now that your ISO file is ready, you can use the Windows ISO burning utility or a free application like FreeISOBurner to create a bootable DVD.
This DVD can be used to install macOS in virtual Windows environments with tools like Virtualbox. You can't use ISO files to install software in Mac, so if this is intended for a computer running Mac OS X or macOS, you will need to convert it back to DMG before you can install the program in question. If you're not confident that you can carry out the steps properly, then continue to Method 2.
Method 2: How to Make a Bootable DVD for Mac on Windows (DMGGeeker)
Conversion processes aren't always accurate and success rate is low for the first method. Many DVD are not able to be used to install macOS due to boot errors. Although DMG2IMG is a great tool, you may find that your resulting ISO file is corrupted and therefore useless. That means doing it all over again. Instead, you can try using DMGGeeker, which allows you to directly burn DMG to a DVD in Windows without having to convert the file. Such a disk can be used to boot a Mac computer.
DMGGeeker is an emerging star in the world of disk image file management software. It allows you to edit, add files to, delete content from, rename and do a lot more with DMG files on Windows without any conversion necessary. If you've been searching for the ideal DMG handling tool for Windows, your search has just ended. Let's see how the process works for creating a bootable media from DMG in Windows. It works with all recent versions of Windows.
Step 1Prepare for Installation
You can download it from the official site here. And then install DMGGeeker on a Windows PC.
Step 2Open DMGGeeker in Windows
Launch the application and click on the 'Burn' option. You'll see the other tools available for DMG files.
Step 3Create Bootable USB from macOS Install Image
Click 'Load DMG' to import your DMG file into the program. Insert a blank DVD and click Burn against the DVD option to write the DMG to the disk.
In three simple steps, your bootable DVD is ready. You won't find that many tools that are so easy to operate. DMGGeeker also has one of the highest burn success rates in its class, which means no wasted DVDs and no wasted time.
Summary
How to choose the rignt tool depends on what the purpose is. If you want to use a DMG file in Windows to mount a version of Mac OS X, then Method 1 will work. However, most of the time, you'll need a DMG to install an OS version on a Mac computer. In those cases, if all you have to work with is a Windows PC, DMGGeeker is the perfect application. It's simple enough for a novice yet robust enough for a professional, it contains all the tools you need to manage DMG files, and it's a life-saver if you only have a Windows PC to work with.

DMG is Apple's file format for disk image, similar to ISO for Windows. It offers an easy information sharing and software distribution for Mac users. But it's not an user-friendly format for Windows since .dmg file can not be natively handled, such as burning DMG to USB. For that reason, no matter what platform you're using, you will need to first convert the DMG into ISO so that it can be used on a Windows machine. We've shown you how to do this on three different platforms: Linux, Mac and Windows.
One thing to remember about this process is that DMG files won't always work for software installations after converting them to ISO. The reason is that applications have to be designed differently for Windows and Mac, and they're not interchangeable. However, you can use this method to extract the contents of the file once it has been converted to ISO. For media and other content types, this is an ideal way to do it.
Part 1: How to Convert .dmg to .iso on Linux (Ubuntu)
The best thing about Linux is that you can complete a lot of tasks totally for free. All apps are distributed in open source license, meaning you don't need to pay a single peny to use the app. Actually, there is a package called dmg2img, which is able to convert .dmg file to ISO with a set of text commands. Taking Ubuntu as an example at here.
Step 1 : Lanuch Terminal app and update the system via this command (sudo apt-get update)
Step 2: After the package installed sucessfully, then input this command to install the package (sudo apt-get install dmg2img)
Step 3: Finally input this command to convert DMG to ISO (dmg2img demo.dmg demo.iso)
Replace the example files with the real file names. You must also run Terminal in the same directory location as your DMG file.
Part 2: How to Convert DMG to ISO on Mac
In a Mac computer, you can use a different command line input in Terminal, or you can use the native Disk Utility to convert DMG into ISO. Both methods have been shown below:
Terminal: The command line input is different from what you would use for Windows. It uses the hdutil program to convert the DMG file into its ISO equivalent. Open a Terminal instance by clicking Applications >Utilities >Terminal.
In the Terminal window, execute this command: hdiutil convert /path/to/example.dmg -format UDTO -o /path/to/example.iso
Be sure to put in the right source and destination files with their complete file paths in the above command. Your ISO file will be ready once you hit Enter.
Disk Utility: Open Disk Utility from Applications >Utilities. Mount the DMG file by double-clicking on it. You will now be able to see it within Disk Utility. The DMG mount must be right-clicked, after which you can choose 'Convert' in the context menu.
In the next dialog box, click on 'DVD/CD Master' when asked to specify the image format. Now hit 'Save'. Locate the saved file, which will be a .cdr file. You can now rename the file and change the file extension from .cdr to .iso.
Part 3: How to Convert DMG to ISO on Windows
To convert a DMG file to ISO in Windows, you will need a special utility. The one we've shown here is called dmg2img, and it can be run from the command line to convert one format to the other. IMG is Apple's old disk image format, which transitioned into DMG with Mac OS X. However, we don't need the IMG format, since we're going to convert the DMG directly into ISO with this method. Follow the steps described below:
Step 1: Download the win32 binary for the application from this page.
Step 2: Go to the Downloads folder in File Explorer and right-click on the zipped file. In the context menu, click on 'Extract All…'

Step 3: Extract it to the same folder (Downloads), then right-click the Downloads folder while holding down the Shift key. This will show another context menu, where you can click on 'Open command window here.'
Step 4: At the command prompt, enter the following command and then Enter: dmg2img source.dmg destination.iso
Step 5: The above command should be modified to include the file path with file name for both the source and destination files. You can choose to create the ISO in the same Downloads folder, or another location of your choosing.
Summary
Windows Convert Dmg To Iso
These different ways are designed to help you convert DMG into ISO, which can then be used on a Windows machine, including ISO burning, editing, creation, etc.. There are several other workarounds for this, but be cautious when using unknown software. If the DMG file is corrupted during the conversion process, the resulting ISO file will be unusable. To make sure there are no problems, only use the command line input or a trusted application for this purpose. If you'd rather not risk using command prompt or free software, there are several premium tools that can help you convert DMG to ISO on Windows, Mac and Linux computers.
