How to Burn an OS X Lion ISO Image to DVD

Insert a blank disc when the burn dialog displays, and then click Burn (make sure to have Disk Utility verify the burn to ensure the media works as it should). To burn the image to DVD, select it in the sidebar and click the Burn button in the Disk Utility toolbar.

To do this, ensure your medium has at least 4GB of capacity. Using Disk Utility, you can either restore the image to a healthy disk partition or burn it to DVD to have it on an optical disc.

First, drag the InstallESD.dmg disk image to the Disk Utility sidebar. From here, you can either burn the disk image to DVD or restore it to a hard drive or flash drive.

Note that you will see an option in the menu to burn the item to disc, but do not use this as it will only burn the item as-is and the resulting disc will not be bootable. Right-click the installer and choose Show Package Contents.

Go to the Applications folder and locate the Install Mac OS X Lion package. At this point, you can either create the installation disc or copy the installer to a backup location so you can create the installation disc at a later point.

When downloaded, it will be added to your Dock and Applications folder, but do not proceed with the installation and instead quit the store and close the installer if it has automatically opened. To purchase and download Lion from the Mac App Store, you will need a storage medium (DVD, flash drive, or hard-drive partition) of at least 4GB in size.

After choosing Show Package Contents on the installer, navigate to this folder to locate the InstallESD.dmg image that contains the Lion installation. Luckily, the OS X installer contains all the materials you need to burn yourself a boot image of the installer, and all you need to do is access this image and then either burn it to DVD or restore it to another bootable storage medium.

The Lion installer will download to your Applications folder and contains everything needed to create a boot DVD. Apple's approach to installing and managing your Lion installation does offer a decent amount of flexibility, but if you would like to have your Lion installation on DVD, then you absolutely can do this.

While its availability solely as a download may have its conveniences, the lack of its initial distribution on optical or other media has been met with a decent amount of criticism, especially by those looking for options to troubleshoot and customize their OS installations.
