After my recent install of Precise Pangolin on my Mac, I came to a black screen that has the usual "Asking all remaining processes to terminate" code. However, at the center of the screen, there's the five dots that cycle between orange and white. Under that, there's a message that says "Please remove installation media and close the tray (if any) then press Enter." Pretty simple. However, when I take my install CD out and press Enter (I don't have a tray), nothing happens. It didn't freeze, because the dots are still going through their cycle. I have the Apple wireless keyboard, but I paired it successfully early in the install. I don't want to restart because of fear that my OS X, Windows, and Ubuntu installs would go haywire. Any help is greatly appreciated.
