a neighboor in my buiding has found in the streets an imac indigo that isn't functionning and asked me to help him. Being skillfull on pc, despite I own an apple II, eons ago, I don't know anything about mac computers nowadays. Searching the web, I found this might be an imac G3 with cd tray loading. When powered on, a folder with a question mark shows off.. I read that this might indicate a disk failure. I tried powering it on with the C key down, it showed me a screen with 2 buttons: an cycling like arrow and an arrow to the right. Inserting the disk1 of panther gives me a icon in the middle of the 2 previous one with a mac osx Disc1 label. Clicking on the arrow to the right, the watch pointer revolves a bit and nothing more. Do you think that hard drive is broken and that prevents me to install any OS?
