10.5.8 to snow leopard
I am trying to install snow leopard to my Macbook Pro. However, when I run the disc, it gives me an error message. "The application "Install Mac OS X" cannot be used from this volume." I have tried partioning, but it does not allow me to change anything. I read the instructions it came with and offers no help. Can someone let me know how I can install the program? Thanks
