Have a few months old Mac Mini with 8GB ram and 500Gb hard drive.    today when I turned it on I got to the initial white screen with the mac logo, and a progress bar at the bottom of the screen.   The progress bar goes to about 5% or so, then disappears.... and soon after that, the system shuts itself off completely. 

I've reset the memory modules, and used Option R to get to the utility screen.  I ran the verify disk and it indicates that the disk needs to be repaired. 

Now when I attempt to repair using the rather poorly documented interface... it appears to direct me to go in circles and I'm unable to figure out just exactly what the process is supposed to be. 

I'm OK with losing all of my data, but I can't figure out how to do a new clean repair or install to start over.   I was running the newest os by the way.

any ideas?>

    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.


    Repairing a Mac Boot Disk with Disk Utility & OS X Lion

    • Reboot the Mac and hold down Command+R to boot into Recovery
    • Select “Recovery HD” at the boot menu
    • At the Mac OS X Utilities screen, select “Disk Utility”
    • Select the boot volume or partition from the left menu and click on the “Repair” tab
    • Repair Disk is now possible, click on “Repair Disk” to repair the boot volume

    Hi.  BDAqua was suggesting "Command + R" not "Option + R" as you had done in the first instance.  If you had done that, try


    That is a brilliant document that should help you through most situations.  I'd suggest that your disk drive has become corrupted somehow - and will need a reformat and complete re-install.


    Also - here is where Apple stand on their own...Your Mac is only a few months old.  Call Support.
