Stuck at grey start up screen
Recently my mac mini will not boot up. The mini gets stuck at the grey start up screen with the apple logo. I tried to boot from OSX install disc no success. I tried pretty much everything but to no avail. I have unplugged it, tried to reset it, no success. I ran the hardware test which I could start and it came back ok. I started the mini in target mode and was able to use its hard drive to boot and start another mini . Anyone have any ideas?
