Before you can install OS X on the new HD you must first set it's Partition Map Scheme to GUID and it's Format to OS Extended (Journaled).


To acomplish that you will need to use the original Disc 1 that came with your iMac or the Retail 10.6 Disc.


1. Boot from your install Disc or Retail 10.6 DVD 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 the Options... button.

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

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

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


Update that OS X version to 10.6.8 and then go to the App Store for 10.8.

You need Mac OS X Snow Leopard to install OS X Mountain Lion. As your hard drive is broken, there is no way to install OS X Mountain Lion without installing Snow Leopard or Lion. Apart from that, as you purchased OS X Mountain Lion, it means that you already used Mac OS X Snow Leopard, so you may have the Mac OS X Snow Leopard disc
