I don't have  my os x  start up disk to reboot my Mac Pro 2008. I have a gray screen. I don't know what to do. I am running mountain lion that I down loaded from the apple store.  What do I need to do to fix my computer with out my disk.

MacBook Pro (15-inch Early 2008), OS X Mountain Lion (10.8.2)
