Hello, I received an iMac for Christmas last year and up until this point had been enjoying the experience quite a bit. A few days ago I turned it on only to be greeted by the grey start-up screen which never went away. I tried booting from the OS X Install CD and checked the Disk Utility function, when I did that the only selection it gave me was the disk drive/install cd. Any help would be greatly appreciated.

Core 2 Duo Aluminum 20", Mac OS X (10.5.8)

    Hi and Welcome to Apple Discussions...

    When you booted from the install disk you were holding down the C key at the same time? If not...

    Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
    Go to Installer menu and launch Disk Utility.
    Select your HDD (manufacturer ID) in the left panel.
    Select First Aid in the Main panel.
    *(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
    Click Repair Disk on the bottom right.
    If DU reports disk does not need repairs quit DU and restart.
    If DU reports errors Repair again and again until DU reports disk is repaired.
    When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
    Select your start up disk and click Restart

    While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. *Make sure there is always 10% to 15% free disk space*

    If you cannot boot from your install disk, try booting in Safe Mode

    What is Safe Mode

    You could also try running the Apple Hardware Test.

    When I try holding down the C key the disk never boots and eventually just ejects itself. When I don't hold down the C key the grey Apple appears for a long period of time until it switches to the blue screen and then eventually the Mac OS X Installer starts up.

    Then when I launch Disk Utility the only things present in the left panel are "MATSHITA DVD-R UJ_875" and "Mac OS X Install Disc 1", there is no HDD option to select.

    Hi Chad

    I hope you were using Time Machine, a backup clone or at least had your user folder backed up.

    The bad news, unfortunately it seems that the HD went south for winter and won't be coming back.

    The good news, your hardware is covered for 1 year from date of purchase or three with Apple Care.

    As Carolyn suggest's call Apple, the local Apple Store or an Apple Service Provider.
