My friend gave me an old Mac he got from his company when they upgraded and dumped all their old stuff. He doesn't know what was done to it before they cleared out, or if it even has a hard drive, but it seems unlikely someone would have went to the trouble of taking it. Anyway, when I try to turn it on all I get it the chime followed by a flashing folder with a question mark on it. From what I've gathered it means it can't find an OS, so the HDD was probably wiped. I don't have a Mac keyboard, just a Windows one, and I'm trying to boot into some sort of recovery menu but so far no combos I've found for a Windows keyboard have worked. Furthest I've gotten was a mouse cursor and a blank grey screen. Does anyone know how to get any OS on this? I would prefer OSX because I've never had a Mac and if like to mess around with it, but I would settle for being able to run Win or Linux on it. Thanks in advance.
