Can't boot system even from internal dvd or external
i suspected my sata hdd had failed as the system would no longer boot. I have since replaced the drive with a seagate 1tb. But can't get the imac to boot from internal dvdrw using the original imac disc, and by holding C before startup. I have also tried to connect two different external dvdrw, one usb and one firewire but neither will boot, i even tried my leopard disc. I have also replaced the ram. Any help would be great.
Is this a good question?
