Hi there,

 

As it says I replaced my internal WD 250gb drive in my late 2006 2.16ghz imac . I followed the tutorials on the net to the tee yet upon trying to boot from Snow Leopard after firing it back up all I get is the Apple logo and the timer . I've tried holding C to no avail . I've held Alt to select the OSX disc yet it still won't boot to get me to Disc Utility . I've even put the old hard drive back in . When I hold Alt on start up it shows the drive and the disc but will boot from neither when selected . I've tried to get the Snow Leopard disc to eject so I can try my originals but it won't even do that . I'm convinced I haven't damaged anything but I'm at my wits end ! Does anybody have any ideas how to get the Leopard disc out so I can at least try from my originals ? The drive I've installed is compatible it's a 1tb WD . I also triple checked all the connections and they all seam sound . Really appreciate your help lads as I wanted to give the iMac to my daughter when we get a new one .

    What OS were you using? What version is on the OEM DVD? Your model iMac would have come with 10.4.x of some sort so 10.6 --- as long as it is retail (and you sound like you used that DVD before).

    This is a long shot, but I suggest you try a PRAM reset.

     

    1. Shut down your Mac.
    2. Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    3. Turn on the computer.
    4. Press and hold the Command-Option-P-R keys before the gray screen appears.
    5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    6. Release the keys.

    You will first need to prep the new drive using Disk Utility on the original 10.4 Disc or Retail upgrade 10.6 DVD. It needs to be Partition GUID Partition Table and Format it Mac OS Extented (Journaled) before you can install and run OS X on it.

     

    1. Boot from your SL install DVD or Bootable Clone and open Disk Utility.

    2. Highlight the new HD in the list of drives and select the Partition tab.

    3. Under Volume Scheme select 1 Partition and click on the Options... button.

    4. Select GUID Partition Table in the drop down window and click OK.

    5. Set the Format to Mac OS Extended (Journaled) and click the Apply button.

    6. Once thats done, then you can do a clean Install, Restore from TM or a Bootable Clone.
