So after a bit of brainstorming, I ended up fixing the issue by resetting the PRAM on all of the iMacs. Last night, when attempting to restore three iMacs to a fresh Install of OS X, I was left with an annoying and slightly frightening message: “OS X Cannot Be Installed On This Computer.” For some strange reason, this happened to me on three different iMacs, all of which previously had Bootcamp partitions.
