hi all I am trying to help a freind so bear with me ! right he has a alu powerbook g4 15 inch i think , his been trying to install osx from a cd that came with his 17inch pb but he cant even boot from this cd ! so we hooked it up in target disk mode with a g5 and installed osx 10.3 from the cd that came with his prev 17 inch pb. when we now boot up his 15 inch pb it starts booting and there is a bar where the apple logo whould be and the background is dark grey this is as far as we get !!! any ideas ? is this a hardware issue or software i was thinking of cloning my hd with ccc in target disk mode and seeing what happens !!!! any help would be very kind !!!
