Hi peoples of MacRumors - I have a problem that's been going on for a long time now and well my Powerbook G4+ is stuck on a flashing folder that shows the Finder logo. I have tried the alt/option key boot which leads me to 2 buttons - which do absolutely nothing. I also don't have the Os X disk because I bought this laptop second-hand so yeah. I don't want to go to Apple or the Genius Bar because I believe it costs money as my laptop does not have warranty and it's no longer supported by Apple. Thanks.
