My macbook pro (snow leopard) won't start - I press start, it chimes, gets to apple logo and below is the rotating cog thingy and then just stays there.


So I've put the install disc in and tried to 'repair' the macintosh HD and the the message 'Disk utility stopped- could not unmount disk'.


So I suppose my question is - how do I unmount the disc?


Can anyone help?


Thank you

MacBook Pro, Mac OS X (10.6.8)
