Sometimes you’ll find yourself in a situation where installing OS X Lion from the app store or from the recovery partition isn’t an option. If you’re installing a new, blank hard drive for example, or perhaps you’re having problems with your hard disk. Here’s how to make a bootable USB drive or DVD, just like one you’d have back in the good old days. And just an FYI – this same process will also work for Apple’s upcoming operating system, OS X Mountain Lion.
First launch the Mac App Store and find OS X Lion. It will be located on the right hand side under Quick Links.
Click the download button.
After clicking download, you’ll be taken to Launchpad (if you’re already using Lion). This will take some time, so you might want to do something else and come back to it awhile later.
Once it’s done downloading, go to the Finder and look for the Install Mac OS X Lion icon in the Applications folder.
Now hold down the control key while clicking on the Install Mac OS X Lion icon, and choose Show Package Contents.
Double click on the Contents folder.
Find and double-click on the Shared Support folder.
Click once on the InstallESD.dmg file to select it.
Now, with this file selected, click on Edit in the menu bar at the top of the screen, and select Copy InstallESD.dmg.
Click on your desktop wallpaper so the menubar at the top says Finder. Then click on Edit again and choose Paste Item.
Navigate to Applications>>Utilities in the Finder and launch Disk Utility.
This is where you’ll have the choice to either create your Lion installation on a USB drive or a DVD. First I’ll show you how to do this using a USB drive. If you wish to use DVD, then skip to the part where you’ll insert your DVD.
Plug in the USB drive you want to use
Note: You’ll first want to save all information on the drive. You’ll have to wipe the drive in order to put the Lion installation on it.
