Won't start up, get circle with line through it

10.6.8

When I turn on my mackBook, The apple comes up on a gray screen.
I hear the harddrive making little scrapey scounds. Then in a minute I get a circle with a line through it.

Do I do some kind of safe start of with the disk that came with it.

Thanks in advance for any help.

Have you tried any of these steps?

A flashing question mark appears when you start your Mac​
