I have found an image of Snow Leopard which is around 7GB in size . I have seen in tutorials people have asked to burn this image on CD but DVD supports 4.7GB and image is far more than this .

I do have an 8GB USB Drive . Is there a way to put this image into USB and make it bootable as I want to install OSX on my old PC . Also currently I dont have access to any MAC or Linux OS so is there a way i can burn this image on USB using windows machine ?
