Hi - I bought a macbook tonight but it has 50% of its HD set up with a Vista partition. I would like to axe that partition. I see I can erase the volume in Disc Utilities, but will that leave an empty partition on my HD or will it get rid of the partition so I have the full 100GB for mac os? I am hoping for the latter. How do I make the latter occur if erasing the partition does not give me the vista owned space?
