If you need to create a bootable OS X Lion disk there are a few ways to do this, but most methods need a little computer knowledge to complete. Lion DiskMaker has been developed to take the pain and hassle out of creating a bootable OS X Lion disk and will create you your very own with one click of a button.
Lion DiskMaker is a small application programmed with AppleScript, supporting Mac OS X 10.6 or 10.7 to burn a DVD or build a bootable USB key from Mac OS X Lion’s Installation program.
Once you launch the application, Lion DiskMaker checks for the presence of a Mac OS X Lion Install in the /Applications folder, or tries to find one using Spotlight. As soon as its located the OS the app then will build either a OS X Lion DVD or create a USB bootable install disk. But note to burn a DVD copy, you’ll need a SuperDrive and a writable DVD single layer, 4.7 GB disk.
You can now download Lion DiskMaker from their website for free. Enjoy!
