Hi Everyone.. This is my first post to the list. I have a G4 Dual 1gHz titanium powerbook which went down a few days ago when I was trying to reinstall the system. I installed the wrong system (for power mac) onto the laptop which now doesn¹t startup at all? It now shows me that flashing questionmark over the folder when booted. I got very scared at this point and thought that I might lose my files so I successfully connected to me powermac via the firewire holding down t¹ on startup.. Then I decided to do zero¹ the drive and install the powerbook install cd onto the powerbook via the powermac (which didn¹t work either) I have also tried: 1: booting form the install cd in the powerbook (doesn¹t work) 2: installing firmware again (but the firmware installer must be run from the destination computer-which isnt possible) didn¹t work. 3: making a boot cd with the system folder on the powerbook install cd and disk warrior, norton, Drive10, but no matter what cd format or file arrangement..... It wouldn¹t boot. Can anyone help me..... I really need help. Thanks Alex
