To create a bootable USB drive from a DMG file on Windows, you will need to have the right utility. That's because DMG is not native on Windows. It is the Mac equivalent of an ISO file that has been in use since Apple transitioned from the IMG format with Mac OS X. A DMG file, like ISO, can be used to install macOS operating system or Mac apps. If the Mac computer was broken or crashed and couln't get into the system, but you only have access to a Windows PC, there's still a way to make a bootable macOS install USB on Windows.

TransMac - Make DMG File Bootable USB on Windows

This is a fairly robust application for creating bootable USB on Windows from a DMG file. However, there's a preparatory step to be executed before you can create the bootable USB drive. The typical disk partition used is MBR, but you will need to do a partition with GPT for this to work. You can do so by executing the diskpart command in Windows CMD. Alternatively, you can do it from within TransMac, as shown in the instructions shown below the next paragraph.

Once this is done, you can download TransMac and use the two-week free trial period to get the job done free of cost. You can always upgrade if you like the utility and want to keep using it after the trial period has ended. Once you download and install the application, insert your formatted USB drive and follow the instructions below:

Step 1: If you haven't formatted the USB, right-click on your USB drive in the left panel and select Format Disk for Mac from the contextual menu.

Step 2: Right-click again on the drive in the left panel and this time select Restore with Disk Image.

Step 3 : Select the DMG file and click on Open. Once the process is complete, you can eject the drive and use it on a Mac. 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. Please note that you can't boot your Mac from bootable USB made from an ISO file, which means you'll have to convert it back to DMG prior to that. Still, it's an effective way to create bootable media for a Mac computer. Here's how it works:

Step 1: Once you have the macOS install DMG file on a Windows PC, click on Windows + R to open the run dialog box, and type in CMD, then hit Enter. When the Command Prompt opens up, use the following command to convert the file to ISO:
hdiutil convert /path/sourceimagefile.dmg -format UDTO -o /path/targetmage.iso

Step 2: Download and install UUByte ISO Editor on your PC, insert the USB drive and launch the application.

Step 3: Click Burn button on the main screen and point to the converted ISO file. The drive will be automatically detected and click on Burn icon to burn the ISO to the USB drive.

Once the ISO is burned to the file, you can insert it into a Mac and convert it back into the DMG format. Since you're converting the file twice, there's a chance that the file could get corrupted in the process. If that happens repeatedly, then try this next method.

PowerISO: Make Bootable Mac Install USB on Windows 10/8/7

This Windows utility allows you do create bootable USB from DMG on a PC. You can also edit the DMG or extract the contents, and there's also an option to copy it to a disk. For this particular exercise, we'll show you how to use PowerISO to create a bootable USB drive on Windows without having to convert the disk image into another format like ISO.

Step 1: Download and install the application on your PC.

Step 2: Insert your USB drive and launch PowerISO.

Step 3: In the Tools menu, select 'Create Bootable USB Drive… '. You will need to give admin privileges to the software. Alternatively, you can run the program as admin when you launch it.

Step 4: Select the USB drive in the section called Destination USB Drive.

Step 5: Leave all other default as they are and click on 'Start' to burn DMG to the USB drive.

Mydmg

You should be able to see the progress, and a new popup will appear when the bootable media is ready. You can now eject the media and use it to run the DMG on a Mac computer.

Conclusion:

All of these methods are workable, so select the right one for you based on your level of knowledge and your preference.

So you’re running Linux on your computer, maybe Ubuntu, and you have some files with the .dmg extension. In this guide, we’re going to talk about how to open, mount, extract, and otherwise get your files from these pesky DMG images. You could always just extract the files on a Mac, then transfer them back to your Linux machine. But if you really want to do this on Linux, without having to rely on Mac, here’s how to do it.

What are DMG image files?

Simply put, it’s a kind of image file. But not an image like a jpeg is an image. DMG is Apple’s proprietary disk image format, native to Mac OS X. There are actually a whole bunch of different types, format and options within this format. There are options for encryption, compression, and different kinds of partition schemes, among others. Unfortunately, this can make things pretty confusing when we’re trying to gain access to the data contained in one of these images.

DMG images are typically a kind of Universal Disk Image Format (UDIF), although there are others, namely NDIF and SPARSE. Although the .dmg file extension is usually used, they can also sometimes have an .img extension, or in some cases no extension at all. Highest dmg class in maplestory 2017. Their MIME type is application/x-apple-diskimage.

The HFS/HFS+ (Mac OS Extended/Journaled) file system is typically used in DMGs. However, this isn’t always the case. You may also sometimes find FAT and ExFAT files systems, as well as variations on HFS.

Does my system support DMG?

Perhaps the biggest hurdle to overcome when trying to work with DMG files is working with the HFS file system (Mac OS Extended). Linux supports HFS through the “hfs” and “hfsplus” kernel modules.

There’s an easy way to test if your system has these kernel modules. Plug in a USB drive formatted with the Mac OS Extended file system. If your particular distribution doesn’t have the appropriate modules, you will likely get an error message. On Ubuntu, you’ll get a popup window declaring “Ubuntu: Unable to mount '.

Alternatively, we can see if the kernel module files are present with find:

We want to see two files: “hfs.ko” and “hfsplus.ko”. If find doesn’t return these files, your system probably doesn’t support HFS.

You could also try “modinfo”: modinfo hfs and modinfo hfsplus should return something like:

If you get 'modinfo: ERROR: Module hfsplus not found' your system doesn’t have these modules.

Not all Linux kernels and distributions support HFS. This is especially the case for certain distributions that are a few years old. If you have kernel support for HFS, great! If not, don’t worry. There are still ways to extract data from your DMG files. While it’s nice to have the option to mount the images we’re working with, this is really the only functionality we’re losing without having the hfs and hfsplus modules. The two programs we’re going to use later on (P7ZIP and dmg2img) do not require kernel support to function.

What kinds of DMG images can be opened in Linux?

This guide is about how to open, mount, and extract files from read/write, read only, and compressed DMG image files. The following partition schemes have all been tested with the techniques discussed here.

• Apple Partition Map
• CD/DVD (partitioned)
• CD/DVD (partitioned) with ISO data
• Hard disk
• Master Boot Record Partition Map
• No partition map

This guide does not cover how to handle sparse disk images (.sparseimage), sparse bundle disk images (.sparsebundle), or CD/DVD masters. DMG images with partition scheme types of “CD/DVD” and “GUID Partition Map” do not appear to work with the techniques described here.

Option 1: Mount the DMG

If the Linux distribution you’re on has HFS support in the kernel (Ubuntu 14.04.1 LTS supports it), it’s pretty easy to just mount the DMG image:

We’re using “sudo” because we need root privileges to mount things. The HFS+ file system type is specified with “-t hfsplus”. The “/mnt” at the end of the command specifies where we’re mounting the image.

Unmount the image with sudo umount /mnt

If you get a wrong fs type message like the one below, it means the DMG file is either of an unsupported type, or it’s compressed. Unsupported images include sparse images, sparse disk bundles, CD/DVD masters, and images with partition schemes of the CD/DVD or GUID Partition Map types.

Use “file” to learn a little more about the image file:

If you get image.dmg: x86boot sector that means it’s probably using a GUID Partition Map and isn’t supported. This isn’t good, however, it’s also not too terribly common.

What’s more common is to see something like this:

If mounting isn’t working, and this is what you’re seeing with “file image.dmg”, then you’re luck!. Our problems are being caused by compression. Linux doesn’t like to mount compressed DMG images. To get around this little obstacle, we’ll use dmg2img (see below).

Option 2: Use dmg2img for compressed images

So you have a DMG image that you can’t mount because it’s compressed. You’ve done “file compressed_image.dmg” and you got “compressed_image.dmg: bzip2 compressed data”. The fix? That’s easy: use dmg2img to convert it to an uncompressed image. Once you run the image through dmg2img you should be able to mount it no problem.

Don’t have dmg2img? It’s usually pretty easy to get using your distribution’s package management. On Ubuntu, you’d do:

Using dmg2img isn’t very difficult. Type “dmg2img” into the command line followed by the name of the DMG file you want to decompress. The Mac OS X version of Firefox is a good example of a compressed DMG file.

For those who don’t, they can make theirs by registering themselves here: Remember, the files need to be unzipped as well.

Now mount the resulting .img file:

Option 3: Extract DMG contents with P7ZIP

P7ZIP is awesome. It’s the Linux/BSD version of 7-Zip. Check out their SourceForge page here With it you can literally extract files from any kind of image or archive. Just kidding… It doesn’t really work with every format conceivable. However, it can handle (in alphabetical order): ARJ, CAB, CHM, CPIO, CramFS, DEB, DMG, FAT, HFS, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, RAR, RPM, SquashFS, UDF, VHD, WIM, XAR and Z. Impressed? I certainly am!

Installing p7zip is pretty easy using your distribution’s package management system. On Ubuntu with apt-get:

In addition to being able to extract data from compressed and uncompressed images alike, P7ZIP doesn’t require the HFS kernel modules at all. In the example below, we’re going to extract all of the files from “Firefox 33.1.1.dmg”. When we’re done, we’ll have a tidy little folder called “Firefox”.

What To Do With A Damaged Bill

Invoke P7ZIP to extract archives and images with “7z x”.

Notice that 7z extracted three files: “0.ddm”, “1.Apple_partition_map”, and “2.hfs”. To actually get to the files, we’ll need to run 7z again on “2.hfs”.

We picked “2.hfs” because it was the biggest of the three, meaning it was probably the one with the data. Simple but effective logic. After a few moments, you should have a folder called “Firefox” with all of the files from the original DMG.
