OS X Lion was sold through the Mac App Store, which made acquiring and installing this operating system a simple task. But what happens if something goes wrong with your Mac, and you need to boot from an install disk? There is no install disk with OS X Lion.
Creating a bootable version of OS X Lion isn't that difficult. When you downloaded the OS, the Lion installer was placed in your Applications folder. When you run the downloaded Lion installer, it simply restarts your Mac using the embedded Lion disk image that is buried in the download file. With a little fiddling, you can use the disk image to create your own bootable copy.
