Yesterday I wrote a post “How To Re-Download Mac OS X Lion & Create a Bootable Install DVD” and it seems to be helping a lot of people out there. So, sometimes it is even more helpful to create a video that explains the process, so I quickly put one together. Also, a few users were wondering how to create a bootable USB Thumb Drive with the same installer so I have added those steps to this post.

Note: if you are looking for instructions for Mac OS X 10.8 – Mountain Lion – please see this post.

First, be sure that you read through the first post so that you understand the steps.

How to Create a Bootable USB Thumb Drive

The steps are very similar to burning a bootable DVD. BE SURE that you have a large enough USB Thumb Drive (the one shown in the video and the example below was NOT large enough at 4 GB).

  1. Download the Lion installer from the App Store (see the steps on my previous post)
  2. Move the Installer out of the Applications folder (e.g., to your Desktop)
    Lion_icon
  3. Right-click on the Installer and select “Show Package Contents”
    show_package_contents
  4. Within the package, go to the “SharedSupport” folder
    shared_support_folder
  5. Copy the “InstallESD.dmg” file to your Desktop
    InstallESD
  6. Launch Disk Utility
  7. Insert your USB Thumb Drive (you can format it if you want)
    thumbdrive_large
  8. Click “Restore”
    restore
  9. Choose the “InstallESD.dmg” image
    select_restore
  10. Drag the partition on the USB drive from the left onto the Destination field and click RESTORE.
    restore_usb

That’s it! Unfortunately, I did NOT have a large enough USB Thumb Drive (mine was only 4 GBs). So be sure you have a large enough thumb drive for this (perhaps 6GB).

Be sure to share this and my previous post with others!
