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.
Jul 08, 2011 Solution: Re-dowload OS X Lion, Open Disk Utility, locate InstallESD.dmg file from SharedSupport folder and double click it (Automatically the InstallESD.dmg and Mac OS X Install ESD is going to mount in the Disk Utility application on the left side), Drag the Mac OS X Install ESD file to the Source and Drag your usb partition (if you have more than one partition on your usb) to the Destination and RESTORE. Dec 10, 2018 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.
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
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.
Make Bootable Usb Drive With Dmg Drive
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.

Windows and Mac, they both are designed with different companies with a different file system. Because of their File system, it seems to us that we can’t create bootable USB for macOS Mojave on Windows. And the same goes for mac, where we are thinking we can’t create bootable USB for Windows 10 in mac. However, if you have used the Mac operating system, then you know that you can create bootable USB for Windows in mac with terminal and some other applications. But if you have used windows you will find out that you are not even able to create bootable USB for macOS Mojave using CMD or PowerShell. However, if we compare the Terminal and PowerShell, Terminal is built upon the Linux Codes and Infrastructure. but PowerShell is built by mixing all Unix, CMD, Scripts and other kinds of stuff. Jeffery Snover the founder of PowerShell said that anyone can work on PowerShell based on their platform. it means that if you are a Linux user you can use PowerShell, just like you are using the Linux terminal. This way PowerShell seems to be Powerful but yet no one has achieved to create bootable USB for macOS Mojave on Windows. I bet that for programmers it is not a hard thing but they are not interested in that. It is we, the basic users who wish to use a different operating system.
So, enough of talk and let’s dive into creating bootable USB for macOS Mojave on Windows with TransMac, I hope it will be helpful for you.
Required Files:
- macOS Mojave Dmg File: In order to create bootable USB for macOS Mojave in windows 10, the first thing which is required is the macOS Mojave dmg File. If you have used a mac operating system, then you know that you can’t download macOS Mojave except for app store. I don’t know how, but programmers have decoded that from mac and uploaded the dmg file for windows users. Now windows user can download the macOS Mojave dmg file and they can use it to create bootable USB. And keep one more thing in your mind, if you visit any site download macOS Mojave iSO, then the flash won’t be bootable correctly. Because of those how are providing you the macOS Mojave ISO file, they have simply converted the macOS Mojave dmg file using PowerISO. Converting macOS Mojave dmg file to any other extensions requires a specific set of skills in the coding of an operating system. So, it is so rare that anyone put that much effort. However, I can’t predict if someone changes the macOS Mojave dmg to iSO in the future.
- 16 GB USB Flash: The macOS Mojave dmg file size is actually is 6.7 GB and at least it requires 8 GB of storage to extract the files. But since many users are facing errors, I would you recommend you to use a 16 GB USB Flash. And please make sure that the USB must be 3.0 because with USB 3.0 it takes 50 minutes to create bootable USB and I wonder How much time it would take for USB 2.0 to Create bootable USB.
- Transmac: TransMac is a software which is specifically built for windows users to mount, format, edit and create bootable for macOS. However there is also alternative software to TransMac but they are working best for Hackintosh file system (HFS), but since macOS high Sierra and macOS Mojave have Apple File system (APS), they can’t support it. Another thing which you must know about the TransMac, that TransMac is not free forever, it only provides you 15 days of trial. But After that, you have to purchase it.
Before creating bootable USB for macOS Mojave in windows 10 using TransMac, you have to download and Install TransMac. Installing TransMac is so simple and it does not require too much attention but in case if you don’t know How to Install. Follow the below procedures:

Step 2. Run TransMac as Administrator, if it is not given the full privileges it can’t create bootable USB for macOS Mojave.
Step 3. Right click on the USB and select format disk for mac.
Step 4. Once the disk is formatted for Mac, again right click and select Restore with Disk Image.
Step 5. Now the TransMac will warn that all files will be overwritten, so you have to click on the Yes and move to the next step.
