So i have a 27inch imac shipped with mountain lion. Once i turn it on it starts to boot then I see a progress bar (like the one for safe boot but i am not holding the shift key or any key), then it would stall at quarter way and then restart or shut down. I booted into the recovery partition and attempted to repair the disk but it said disk utility cannot repair this disk and i should backup and restore the machine. I tried single user mode with fsck but preety much the same error and exited with signal 8. I know the hdd is not defective as it was tested at an authorized apple location. i also know a restore will fix this as I had this same problem a few days ago an a different mac and formatting, partitioning fixed it. I can restore the system now that I found the files i needed backed up somewhere else on the cloud. However did anybody get this before or know the reason, solution?

I think you may have a hardware problem, but to be sure, do the following.

 

1 - Hold the D key down and press the start button.

 

2 - A hardware test from Apple's server on the Internet will present itself.

 

3 - Run the test.  It doesn't take as long as the old DVD tests on Snow Leopard.

 

4 - Record the codes and call AppleCare 1-800-MYAPPLE or call your nearest Apple Authorized Repair Center.

Was the startup disk's S.M.A.R.T. status Verified when you used Disk Utility from the Recovery Partition?

I took it to the apple store and they booted off their network for a quick hard ware test and everything passed including hdd smart test. I could not leave it as I needed to do some work on it.
