See if it will start up from your original system installation disk. If so run Disk Utilities on the hard drive.

It won't use the disk or take any commands.


Disconnect the hard drive and try starting from your optical drive with your system installation disk. iMac Intel 21.5" EMC 2389 Hard Drive Replacement


Thank you so much for the link. I followed the steps but when I removed the LCD thermal sensor cable the light colored wire was out, I don't know if I pulled out or it was like that, guessing I pushed it back into the hole next to the dark colored wire. When I tried using the system installation disk to start up it went to and stayed on a screen with a file with a question mark flashing.


I tried to start again but only got a blank screen.
