Can a 'broken' hard drive create a complete boot failure?
I've a G4 of unknown origin that I'm trying to repair, I have no previous knowledge of MAC's, but can deal with PC's.
At every boot I end up with the generic failure symbol.
So far I've reset the power management, reset the nvram and tried to diagnose the hard drive externally on a PC, this also fails to detect the HDD in the BIOS.
With a MAC OSX disc I've tried to boot from the CD, I don't get the boot drive options, I get a refresh and continue only.
So, if I replace the hard disk, which gives all the indicators of being faulty, will I be able to boot from the O/S disc and perform a fresh install, or is there another issue preventing the boot disc options from showing?
