I just bought this powerbook from the internet for a nice price. The system is damaged so i need to re-install it... This is the first problem Something is blocking my way in the disk drive slot it doesn't feel like a CD.. But i can live without a CD drive. So i wanted to install Mac Os X 10.4 from USB, I need to boot from an USB drive with OpenFirmware. But by pressing: Alt + Apple + O + F before i press the power button (And holding it after) i will still hear the Boot sound and the system is starting to boot (But keeps spinning for ever. HDD I/O Error while loading /sbin/launchd error 5) How am i gonna fix this? Since the system shows the spinner there isn't real hardware damage I wont go to a apple store. I would need to ride 100KM and it will cost me more then i paid for it I would like to fix it without opening the powerbook, i will likely damage it.
