How To Make A Bootable Lion Disc

With Lion only available via the Mac App Store and Apple not offering the option of Lion on a USB drive until August (and at $69), how can you boot a machine from a Lion disc to perform a clean install? You can make a bootable DVD. Details inside.

Once you have the Lion installer downloaded from the Mac App Store (available here), to your Applications folder and right click or ctrl+click “Install Mac OS X Lion” and select “show package contents.”

Now open the “Contents” folder and then open the “ShareSupport” directory. Inside this directory you will see InstallESD.dmg. This is what you will need to burn to have yourself a bootable Lion install disc.

Simply fire up Disk Utility (/Applications/Utilities/Disk Utility) and then drag the InstallESD.dmg file onto the Disk Utility sidebar:

Then click burn and insert a blank DVD in your burner and burn! That’s it, you have now a bootable Lion DVD that you can use to install on any Mac you wish.

  1. Thanks for this great tip.

  2. can’t drag DVD drive to destination box. Works with a USB drive, but not a dvd. it is “greyed out” like in your picture above.

  3. @Bomo you read it wrong. Drag the dmg into the sidebar as shown above. Then hit the big yellow and black ‘burn’ button. Insert a DVD and let it burn. Yeow.
