I bought new MBP some days ago and it came with the lion installed on it. Now I am curious can I make an OS X Lion Bootable Disk?

I read some tutorial to make an OS X bootable Disk if you download it from appstore, but if Lion was installed by factory on it how can I make a bootable disk?

  • The Recovery Disk assistant makes a minimal lion boot system, installing Lion onto pretty much any disk is bootable so put whatever you want there... What exactly are you asking?

  • @bmike I want to burn my Installed OS X Lion on DVD, so I can install it on other system or my MBB every time I want.

  • OK - so you'll need instructions how to set the system to boot on a read-only filesystem as well as break the installer so that it runs without talking to the store - or is it acceptable to talk with the store to verify the installer - run the normal Lion packages?

Open Terminal, and type this command to list all partitions on your hard drive or SSD:

diskutil list 

Identify the "Recovery HD." For example:

   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *120.0 GB   disk0
   1:                        EFI                         209.7 MB   disk0s1
   2:                  Apple_HFS Filesystem              119.2 GB   disk0s2
   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3

Then run the following (replacing [ID] with your identifier (will most often be disk0s3).

diskutil mount readOnly /dev/[ID]

So the following would look like:

diskutil mount readOnly /dev/disk0s3

The disk image inside the Recovery HD partition has been marked invisible, so use the Terminal command to mount it:

hdiutil attach /Volumes/Recovery HD/com.apple.recovery.boot/BaseSystem.dmg

Now, from the newly mounted Mac OS X Base System Image, double-click the 'Install Mac OS X' application and proceed past the licensing agreement.

Choose the external drive or spare partition when the installer asks where you'd like to install OS X Lion.

Once the installer completes the download, do not restart your system. Rather, quit the installer. If you restart, you'll likely lose the local Lion installer. Once you have the InstallESD.dmg in the Mac OS X Install Data folder, you can burn it to a DVD, or image it to a USB flash drive to create your very own Lion boot disk.

  • Wicked awesome! Great detail and links to sources :-)

You need to visit the Mac Up to Date WEBSITE and you can then get a code from the website to download Lion and create the bootable disk from there.

  • "Customers who purchase a qualifying new Mac Computer or an Apple Certified Refurbished computer from the Apple Online Store on or after July 21, 2011 that does not include OS X Lion can upgrade to OS X Lion for free." His machine came with Lion, he does not qualify.
