I would also put a copy of the installer on a bootable USB key. &nbsp;Lion and Mountain Lion each need about 5 GB for the task. &nbsp;That way you are covered even in the case of a crashed or dead drive.<br />
<br />
Instructions for Lion can be found <a href="http://osxdaily.com/2011/07/08/make-a-bootable-mac-os-x-10-7-lion-installer-from-a-usb-flash-drive/" rel="ugc">here</a>.<br />

The instructions are essentially the same for Mountain Lion. &nbsp;The link for ML is in fact at the bottom of the page.

Rebuild Imac

Apple's early computers ran on a variety of operating systems, including a Pascal version and one based on CP/M, before releasing its ProDOS with the advent of its 16-bit computer. With the release of the Lisa, which had its own OS, Apple and computing entered the graphical age; it was followed by the Macintosh, which offered a series of "System" operating systems. Other Mac operating systems included PowerPC until Apple acquired NeXT and folded it into the Mac OS. Current operating systems for Apple devices are Mac OS-X and iOS.

Apple OS

Mac OS X is the desktop operating system from Apple Inc., found on Macintosh computers. OS X consists of a Mach/BSD-based kernel, operating system interfaces primarily based on FreeBSD and additional frameworks (written in C, C++ and Objective-C providing user interface and application-level services.
