But, I posted on how to create Mac OS X Lion boot disc earlier.
Now, there is an even easier way to create your own Lion boot disc.
Lion Diskmaker is a simple app that creates a Lion boot disc for free. It just needs to known where your Mac App Store download is and it can extract the contents and create boot disc out of a USB drive (4 GB) or a DVD.
If you haven’t upgraded to Mac OS X Lion yet, it is an amazing upgrade for just $29.99! That is a steal.
