Q: grey screen, then shutdown

Hi.

I have a problem with my mac mini from 2010 (It's a 2009 model). It wouldn't start. It's starts up with the grey screen and the loadingbar. It takes for ever to finish and when it does it just shutsdown. I'm starting to belive that the HDD is fried... Anyone who has tried this...?

I have tried different things:

 

- Start up in AHT

- reset NVRAM

- Startup Manager (it saids my HDD is locked, and i can't unlock it, i have password but nowhere to unlock!!!)

 

 

not tried yet.

 

- Starting up in single-user or verbose mode

- Target disk mode

Mac mini, iOS 6.1.4

    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...

     

    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive

     

    "Try Disk Utility

     

    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.

    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)

    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*

    3. Click the First Aid tab.

    4. Select your Mac OS X volume.

    5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."

    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.

     

    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive & clear caches.)

     

    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

     

     

    If 10.7.0 or later...

     

    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

     

    Did you setup Firmware password protection in Mac OS X ...

    It would block usage of all the startup keys, like C, N, T, D, CMD+s, CMD+Option+p+r, CMD +v, Option boot will show a lock, and Shift, as well as booting from anything but the Hard Drive.
