My iMac won't boot up!
My iMac 27" won't boot up. This is what I've done in hope to repair it.
Try to boot from my install disk, nothing.
Try using a bootable USB with the OS X installed, nothig.
Did however boot using target disk from my macbook.
Using my macbook I erased the entire hard drive and installed a new OS X 10.6 still, but it all finish and restarted, nothing.
I did also reset the SMC, the PRAM, force start using the key X, nothing.
However if I use startup disk, using the firewire and select the hard drive from my iMac(won't boot) from my macbook it will boot up, but from my tiny macbook screen.
