What software can be recommended to burn a Mac created .DMG file on a Windows operating system? Ideally it should be free, or at least reasonably priced.

Or, as an alternative, an application convert it to .ISO or something equivalent?

I'm looking for reassurance I won't be wasting several (more expensive than normal DVDs) dual layer DVDs to get this done right. As the .DMG file is 7 GB.

Personally, I like MagicISO.

MagicISO was struggling with some of my .DMG files but worked with others. – Nick Josevski Jul 27 '09 at 8:03

This is what worked for me:

I have Windows 7 64-bit and needed to burn a 6.36 GB 10.6.3 Snow Leopard image to a DL DVD on my PC to install on a Macbook Pro. I am no stranger to PCs as a repair technician, but I have little experience with Macs.

I used Power ISO 4.7 in Windows 7, selected the "Tools" and then the "burn" pull down menu. Point to the .DMG image file on your PC and have a DVD/CD in the burner big enough to hold the image, select your burn speed and that is it.

Hold the "C" down after you press the power button on the Mac and hear the Apple tone to boot to the new image.

I did use my Windows 7 DVD to wipe all partitions from the Macbook as that was what I was familiar with. I was then able to create a new partition with the Mac OS DVD I created.

The .DMG file is essentially your installer on a Mac.

NTFS / FAT32 transfer limits most likely won't let you move this file to an external drive or USB stick.

The easiest way is probably to use WinZip on Windows, and split it into separate files. Then burn each to a DVD or CD.

Yeah JP, I also love MagicISO – Charlls Jul 15 '09 at 23:32
This is not strictly accurate. While they are used for application distribution, .DMG files are not installers as such. They are volume archives and are more closely related to disc images. – dulaneyb Jul 15 '09 at 23:55

What limits prevent .dmg files? I don't understand. I have put .dmg files on Windows partitions plenty of times – David Pearce Jul 21 '09 at 5:09
It's not the .dmg file, it's the fact that it's 7GB. – Charlls Jul 21 '09 at 15:58

Huh? NTFS has a 2-terabyte file size limit. There's no such thing as a "transfer limit" unless you're transferring a file larger than 4GB to a FAT32 volume. – ithcy Nov 15 '09 at 0:27
