Hi guys, A friend of mine has entrusted me with his Powerbook G4 which he seems to have royally screwed up. When I started it up, I get the folder with the question mark. When I try and reboot with "option" selected. I get a lock, a place where I can enter some sort of password and the arrow pointing to the right. What has he done? Will Disk Warrior fix this? I have till Monday, I hope I can untangle the mess he's made.
