i have been given an ibook g4 to look at that will not boot into os x ( 10.4.11) i am unable to boot from cd( not sure why it wont even booting using option key wont let me) but can boot to single user mode, after reading alot on the net i have reset the pmu and pram then booted into single user mode and run fsck -fy which says that the volume is good, so i then tried to use the disk utilitybut no matter what command i use it always says segmentation failed. i think that basically that the os x on the hdd is corrupt but have no idea how to solve this, anyone got any ideas as they will all be appreciated
