With Mac OS X Lion and a new piece of free software, it's easier than ever to create a USB keychain that you can boot from. All you need is a few minutes, a copy of Lion, and a USB flash drive with at least 4GB of storage (though more is preferable). The first step in getting Lion onto your USB drive is to obtain a copy of the OS. A broken Mac computer with Mac OS X. A trial copy of the TransMac software. One high quality USB flash drive with 16GB of storage. A copy of Apple's macOS (DMG file). Now that you have all the necessary ingredients, you're ready to make a Mac OS X bootable USB using the DMG file of the operating system with the steps below. Click Mac OS X Install ESD in Disk Utility's sidebar, then click the Restore button in the main part of the window. Drag the Mac OS X Install ESD icon into the Source field on the right (if it.

On every OS X Lion installation a hidden partition is created to enable a method for Lion to be reinstalled on the machine, it is known as the recovery partition or drive and is 650mb in size.
After the download is complete, the utility will appear in the 'Programs' folder installing Mac OS X Mountain Lion. Right-click on the installer and select 'Show package contents.' Next, copy the OS image from the 'SharedSupport' folder to any convenient place InstallESD.dmg. Create a bootable flash drive or Mac OS X drive. Note that this article covers versions of Mac OS X Prior to Lion (Mac OS X 10.7). We also have instructions for creating a Lion-installer drive. Step 1: Disk Utility.
If you bought a new machine from Apple you have OS X 10.7 already installed – but no back up disk! and since you haven't bought the OSX Lion 10.7 App from the App store you can't re-download it – so thats why you have the recovery drive as a partition in your main hard drive and to boot from it you need to restart the machine holding down 'command' + 'r' keys.
From recovery mode you can run Disk Utility, get online help and do a restore from a Time Machine backup and re-install Lion leaving all your other files intact – it just replaces the core operating system.
You can make a bootable USB drive or disk of the recovery drive, but involves a small trip to the Terminal….
1) Launch Terminal from /Applications/Utilities and run:
The primary drive in this list is No.2 with the 'Identifier' of disk0s2, the boot recovery drive is disk0s3
We can also identify the recovery drive by the name and the size – set at 650mb
2) Mount the drive:
Output should be:
Now the Recovery HD is mounted in the Finder and you can see it in the sidebar under Devices
Navigate to it from the sidebar – Recovery HD/com.apple.recovery.boot/BaseSystem.dmg.
3) Doubleclick BaseSystem.dmg to mount it also in the sidebar. This will mount the volume ' Mac OSX Base System'

4) Open Disk Utility in /Applications/Utilities
5) Put in a 2GB+ USB drive, let Disk Utility load it. The USB drive needs to be formatted as Mac OS Extended Journaled, if its not, its time to format it in Disk Utility…
6) Finally in still in Disk Utility, select the 'Restore' tab – drag the mounted volume 'Mac OSX Base System' into the Source field and drag the USB drive 'Volume' (mine is called SuperBootUSBDrive) to the Destination.
