How To Burn A Mac OS X Lion Install Disk

Apple has announced that for the first time will ever it will be offering it's latest OS X update as download-only via the Mac App Store. But what happens if you want to do a clean install of OS X Lion, or have a back-up disk just in-case?

Well for those of you that like the idea of clean installs or just want to Burn your own Lion DVD Richard Austin of Blog Champion has figured out the steps needed to create your own Mac OS X Lion install disk once it's available to everyone next month.

Here's the steps needed:

  1. Download Lion from the App Store.
  2. Locate the Lion installer file in your Applications folder from the Finder. Right click the icon and select "Show Package Contents."
  3. Open the Contents folder and locate the file called InstallEDG.dmg. Copy it to your desktop.
  4. Open Disk Utility (just search for it using spotlight) and click the yellow and black Burn icon. Select the InstallEDG.dmg file from your desktop and drag it to your DVD-R to burn it.

Now you may ask why I would want to do a fresh install and not the in-place upgrade. For most people a quick upgrade is great. It will preserves most of what you already have on your machine and you won't need to re-install anything. It will be the quickest easiest way to go.

For me, I like to start from scratch when I install new operating system or major update. This allows me to remove any remnants of old software, registry entries or anything else that might be hanging around. I get to experience things the way new users experience things when they start up their new Macintosh or PC for the first time.

It also forces me to think about my back-ups. If I haven't backed up recently doing a clean install will force me to do one. It will force me to update any of my apps but that too is welcomed as it then removes anything that might have been outdated.
