Astronomy and dmg file type. 3. Click on the Browse button and locate the .dmg installer for OS X Lion. (ie mac_os_x_10_7_11a390.dmg)

5. Hold Option/Alt after your see the Apple logo appear and boot with the thumbdrive in your Mac.
Choose the USB Drive to install OS X Lion from your USB Thumbdrive!
