Hi there, hope someone can help. I am trying to get windows 7 onto my 2008 Imac 2.6 20" Aliminum computer. I downloaded the drivers OK, inserted the Windows 7 home Premium disc (original boxed Microsoft, it does have the word upgradeon the box?) the imac spins the disc up and then I hit install. I get a beachball then the mac ejects the disc. I close bootcamp and try and read the disc, It wont recognise it? I have tried both the 32 and 64 version, both the same. If I put either disc in my 2009 macbook pro it reads the disc.......... Is my imac obsolete already? Can I upgade the firmware for the drive? is it faulty? it reads dvd movies OK and loads mac osx or other software. Thanks for your help, I am really confussed,
