so i have followed all the instructions fine, and now i'm at the booting stage. It boots up from the ModCD fine, but then when i swap the disks round and press f5, the "mac osx86" button goes and i am left with the 3 windows buttons. It does not come up with an "install snow leopard" button or anything. Now it will not even run my normal windows 7 again, i get the BSOD! Please help ASAP someone!
