Burn a DMG or ISO File to Disk
After you have downloaded a program's installation file (*.dmg format for a Mac-compatible program, *.iso format for a Windows-compatible program) to a Macintosh computer's hard drive, you can burn this *.dmg or *.iso file to a blank CD or DVD. You can use this disk to install the program on another computer, or have a backup installation disk in case you need to reinstall the program in the future. You can use a Mac to burn an *.iso file to a disk, and the resulting installation disk will run properly on a Windows computer.
Note: For .dmg or .iso files that are larger than 4.7 GB, you will need to use dual layer DVD. See About Recordable Media Types for more information about different types of recordable DVDs.
To burn a DMG or ISO File to disk:
Start Applications > Utilities > Disk Utility. The Disk Utility window will open. The Mac's available drives (e.g., hard drive partitions, CD/DVD drive) will be listed by name in the left pane.
Insert a blank CD or DVD disc into the Mac CD/DVD drive. Note: If the CD is blank, the You inserted a blank CD pop-up window will appear. Select Action > Open Disk Utility, then click OK. The Disk Utility (a.k.a. SuperDrive) window will reappear.
Drag the *.dmg or *.iso file from a Finder window or the desktop to the Disk Utility window, and drop it in the left pane in the empty area below the Mac drive names. The *.dmg or *.iso file name will display in the left pane of the Disk Utility.
Note: You can drag and drop multiple files to the Disk Utility.Select the *.dmg or *.iso name in the left pane of the Disk Utility, then click Burn (top left). The Burn Disc In: window will open and display the destination (your blank CD/DVD) for your file.
In the Burn Disc In: window, click Burn. The Disk Utility Progress window will open and the burning process will begin.
When the burning is complete, the disk is ejected from the drive and the Disk Utility Progress window displays a message that the image burned successfully. Click OK. The Disk Utility Progress window will close.
You can now close the Disk Utility and use your installation disk.
About Recordable Media Types
There are two types of recordable CDs and DVDs: CDs and DVDs labeled 'R' can only be recorded on once, while those labeled 'RW' allow you to write data to them once and then add more files later. You can also erase the data on CD-RW or DVD-RW disks entirely and re-use them, which you can't do with DVD/CD-Rs. You can use either kind in IT Computer Classrooms.
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
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.

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.
