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.

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.

For dmg or *.iso files that are larger than 4.7 GB, you will need to use dual layer DVD.

Home > Resources > Make Bootable USB Installer from DMG

(0 comments)

DMG file is a compressed file format being used widely on Mac computer. Windows OS doesn't natively support DMG disk image files, so if you need to create a bootable USB drive from a DMG file, mostly for bootable Mac OS X or macOS installation USB, you need a special utility to help you complete the task.

There is also the possibility of converting the file into a format more suitable for Windows, which is the ISO file format for disk images. Considering the above, let's look at different ways to create a bootable drive from a DMG file on a Windows computer.

Part 1: Convert DMG to ISO and Make Bootable USB from ISO

Since Windows doesn't offer native support for DMG files, you can first convert the file to ISO. Why? A lot of easier to find an app for making a bootable USB from ISO file. The easy way to do this is to use Command Prompt. Don't be intimidated by the non-GUI environment even if you don't have any experience. If you follow the steps below, you can convert any DMG file to ISO and then create a bootable USB using the converted file.

Step 1: Open Command Prompt by typing cmd in the Run windows and hitting Enter.

Step 2: In the command interface, go to the directory in which the DMG file is saved. You can do this by using the 'cd' command followed by the file path, then pressing Enter. For example, if your disk image is in D: and Command Prompt is currently in 'C:', then type 'd:' (no quotes) and press Enter. If it is in a subfolder, type 'cd subfolder', and so on.

Step 3: Use the following command to convert the DMG file to ISO:

hdiutil convert /path/sourceimagefile.dmg -format UDTO -o /path/targetmage.iso

Step 4: Once the ISO file has been created, you can use a burning tool to create the bootable USB drive. To do that, continue with this guide.

Cons:

File damged or broken after conversion.
Failed booting from burned USB disk.
May not work with the latest DMG file.
Complex and take more time.

Part 2: Create Mac OS X Bootable USB Installer from DMG

Androidphonesoft DMG Editor is a powerful software application for Windows that will allow you to manage the non-native DMG format even if you have no experience. The interface is uncluttered, and you can even use the tool to view files, extract them, edit the DMG and even copy it to a disk. The burn function has one of the highest success rates in the industry, which makes this an ideal utility for our purpose.

Created by the talented team of developers at Androidphonesoft, DMG Editor is currently the most intuitive Windows app for handling Apple's disk image format. Each of its functions have been tested on various Windows versions, with different types of DMG files and on different PC brands. This thorough testing means no wasted DVDs or corrupted files. As long as your DMG file is in good shape, you can directly create a bootable disk.

Step 1 Install DMG Editor

Download and install DMG Editor on your Windows PC.

Step 2 Plug in USB Drive

Launch the application and click on the 'Burn' section. You will also see other modules such as Edit, Extract and Copy.

Step 3 Start Burning ISO File to USB

Now import the DMG file by clicking the 'Load DMG' button, and click on 'Burn'.

In a few moments, your bootable USB flash drive will be ready for use. Since you haven't done any conversion, you can use this directly on a Mac for program installation, which you cannot do with the first method.

Part 3: Create Bootable USB from DMG in Windows Via PowerISO
