Guys I am having problem with step 2.
"When everything is loaded, remove the Boot CD and insert your Apple Leopard Retail DVD into your drive. You should see the word 'BOOT', when the DVD is recognized, press Enter.

It should now start to boot the Retail DVD, after a few minutes you will reach the OS X installation screen"

When I see the word boot and insert my Apple DVD, I press enter. Then it askes me which partition I want to use (81 or 80) After I pick that, another question pops asking which drive, when I pick the drive and hit enter, it says bootmgr is missing. What is wrong? I am using Windows 7 64 bit currently..
Really appreciate your help
