Since my iMac came to me without media (install or any other kind of disks) and with 10.7 installed (the latter updated to 10.7.1), to be on the safe side, how would I create a bootable install disk from what is being called a recovery partition (or, alternatively, a restore partition) which ostensibly holds the information?
[I need any description of how to go about this in plain English so that I might have a ghost of a chance of actually accomplishing such a task.]

This iMac has an integral CD/DVD burner (or so I'm told).
