DMG files are a Mac OS X Disk Image files. like ISO files, DMG files are essentially disk images, which are intended to be used with the Mac operating system. The DMG files normally contain program installation files for Apple system and applications, but they can also be used to hold compressed files. With PowerISO, you can manipulate dmg files on Windows PC. PowerISO can burn dmg file directly to a CD / DVD disc. You needn't convert dmg to iso file before burning.

If the.DMG file that you have is an image of an original Mac OS X 10.6.4 DVD, it will already be bootable. All you have to do is burn the image to a DVD, using Apple's Disk Utility (found in the /Applications/Utilities folder on any Mac OS X installation). With PowerISO, you can manipulate dmg files on Windows PC. PowerISO can burn dmg file directly to a CD / DVD disc. You needn't convert dmg to iso file before burning. To burn dmg file on Windows PC, please follow the steps, Run PowerISO, and insert a blank or rewritable optical disc in the drive. Open up Disk Utility from your Applications Utilities folder and drag the DMG file into the sidebar on the left. If you’re burning to DVD: insert your disc, select the DMG file in the sidebar.

[Editor’s note: This article is part of our series of articles on installing and upgrading to Lion (OS X 10.7). We also have a complete guide to installing and upgrading to Mountain Lion (OS X 10.8).]

Unlike previous versions of Mac OS X, Lion (OS X 10.7) doesn’t ship on a bootable disc—it’s available only as an installer app downloadable from the Mac App Store, and that installer doesn’t require a bootable installation disc. Indeed, this lack of physical media is perhaps the biggest complaint about Lion’s App Store-only distribution, as there are a good number of reasons you might want a bootable Lion installer, whether it be a DVD, a thumb drive, or an external hard drive.

For example, if you want to install Lion on multiple Macs, a bootable installer drive can be more convenient than downloading or copying the entire Lion installer to each computer. Also, if your Mac is experiencing problems, a bootable installer drive makes a handy emergency disk. (Lion features a new recovery mode (also called Lion Recovery), but not all installations of Lion get it—and if your Mac’s drive is itself having trouble, recovery mode may not even be available. Also, if you need to reinstall Lion, recovery mode requires you to download the entire 4GB Lion installer again.) Finally, a bootable installer drive makes it easier to install Lion over Leopard (assuming you have the license to do so).

Thankfully, it’s easy to create a bootable Lion-install volume from the Lion installer that you download from the Mac App Store; just follow the steps below.

Update: When this article was originally published, the Mac App Store version of Lion would not boot any Macs released in mid-2011 or later, as those models shipped with a newer version of Lion preinstalled. However, unlike with the CD- and DVD-based Mac OS X installers of old, Apple can—and does—update the Mac App Store version of the Lion installer. So if you create a bootable Lion-installer drive using the current version of the Lion installer—which, as of 2/10/2012, installs OS X 10.7.3—that drive will work with all current Lion-capable Macs. If your only Mac was released after Lion, so you can’t download the Lion installer from the Mac App Store, I’ve also provided instructions for creating a bootable Lion-install drive for newer Macs.

Part 1: For all types of media

Once you’ve purchased Lion, find the Lion installer on your Mac. It’s called Install Mac OS X Lion.app and it should have been downloaded to /Applications.
Right-click (or Control+click) the installer, and choose Show Package Contents from the resulting contextual menu.
In the folder that appears, open Contents, then open Shared Support; you’ll see a disk-image file called InstallESD.dmg.
Launch Disk Utility (in /Applications/Utilities).
Drag the InstallESD.dmg disk image into Disk Utility’s left-hand sidebar.

The next steps depend on whether you want to create a bootable hard drive or flash drive, or a bootable DVD. I recommend a hard drive or flash drive—a DVD will work, but it takes a long time to boot and install.

To create a bootable hard drive or flash drive

Burn Mountain Lion Dmg To Dvd Software

In Disk Utility, select InstallESD.dmg in the sidebar, and then click the Open button in the toolbar. This mounts the disk image’s volume in the Finder. The mounted volume is called Mac OS X Install ESD.
Click Mac OS X Install ESD in Disk Utility’s sidebar, then click the Restore button in the main part of the window.
Drag the Mac OS X Install ESD icon into the Source field on the right (if it isn’t already there).
Connect to your Mac the hard drive or flash drive you want to use for your bootable Lion installer. This drive must be at least 5GB in size (an 8GB flash drive works well), and it must be formatted with a GUID Partition Table. Follow Steps 1 through 4 in this slideshow to properly format the drive.
In Disk Utility, find this destination drive in the sidebar and then drag it into the Destination field on the right; if the destination drive has multiple partitions, just drag the partition you want to use as your bootable installer volume. Warning: The next step will erase the destination drive or partition, so make sure it doesn’t contain any valuable data.
Click Restore and, if prompted, enter an admin-level username and password. The restore procedure will take anywhere from five to 15 minutes, depending on your Mac and the speed of your drive.

Note: In versions of the Lion installer prior to 10.7.4, you didn’t need to first mount the InstallESD.dmg image—you could simply drag the image itself into the Source field. However, with the 10.7.4 installer, you must use the mounted Mac OS X Install ESD volume or you will get an error at the end of the restore procedure and the newly created bootable drive may not function properly.

Part 2b: To create a bootable DVD

In Disk Utility, select InstallESD.dmg in the sidebar
Click the Burn button in the toolbar.
When prompted, insert a blank DVD (a single-layer disc should work, although you can use a dual-layer disc instead), choose your burn options, and click Burn.

You can now boot any Lion-compatible Mac from this drive or DVD and install Lion. You can also use any of the Lion installer’s special recovery and restore features—in fact, when you boot from this drive or DVD, you’ll see the same Mac OS X Utilities screen you get when you boot into restore mode.

Note: As explained in our main Lion-installation article, if you leave the Lion installer in its default location (in /Applic
