Inheriting an old Mac does not always mean it’s ready to go with freshly reinstalled software. The Startup (Boot) Manager might show its friendly face sometimes when a valid boot drive can’t be found:
Recently I have been given a iMac G5 (light sensor). The guy who gave it to me has wiped the HD so I can start again. I intend to give this Mac to my parents for a present but before I go and buy a copy of OSX i decided to try and install a borrowed copy just to make sure the computer still works. As far as I know the copy works. But my Mac won’t have any of it. (don’t worry, I’m not asking you for advice on pirating). All that shows on the screen are two buttons. One has a circular arrow and the other has a straight arrow. Nothing happens when I click on either of them.
