How do I erase a new drive from a bootable cd Snow Leopard cd? The new drive started with a windows image stuck in the optical drive. Now the Bootable Snow Leopard doesn't see a drive.

MacBook, Mac OS X (10.6.5)

    Welcome to the Apple Support Communities

     

    Go to Utilities menu > Disk Utility and select the hard disk at the top of the sidebar.

     

    Then, go to Erase tab and erase the disk with "Mac OS Extended (Journaled). Finally, close Disk Utility and install Mac OS X

    Tony, did you partition the disk as GUID? That,s required to be bootable by OS X. The instructions here are for Tiger and Leopard but it hasn't changed.

    I'm just a little confused here...you said this was a new drive? When you start up using the Snow Leopard DVD are you selecting your language and at the next screen going to the menu bar and under Utilities are you starting Disk Utility?

    Ok .....so I read all of that and nowhere does it mention that you're using Disk Utility the way I suggested from the install disc. At the second screen, the one immediately after you select your language are you going to the Utilities menu and starting Disk Utility? The disk is unformatted and the only way the Mac is going to see it in that state is through Disk Utility. That's where you partition and format the drive.

    You can force the optical drive to eject y restarting while holding the trackpad button down, or by opening Terminal in the Utilities folder and typing the following

    Drutil eject

     

    If the drive has a mechanical failure that won't allow it to eject it will have to be replaced.
