I recently installed a new SSD hard drive to my 2009 13" Macbook Pro. I cloned my old Snow Leopard HD on to the new SSD and then upgraded to Mountain Lion. My problem is I can't get Windows 7 to install using the Mountain Lion Bootcamp. It worked fine when I had Bootcamp with Snow Leopard but now the installation progress just stops at the extracting windows step at 20%. I have tried it 4 times and it stops between at the extracting windows step at 5-20% every time. Anyone have any idea why this is happening? Is this a Mountain Lion bootcamp issue or a Windows issue? I tried installing both he 32 and 64 bit Windows install disks so I don't think it is a scratched CD issue.
