Need help on changing partition for Windows 7- Mac user? -

Hey. Today Windows 7 Beta came out today so I am trying to install it via Boot Camp. I am a new Mac user so this is why I have trouble so I need a Mac user help. During the Boot Camp setup, I made a partition on my hard drive to allow space for Windows 7. When I try set up stuff with the Windows 7 installer, it wants a different format of a partition. It wants NTFS. How can I change my hard drive format to NTFS so I can use the OS?

Mac OS does not support writing under NTFS out of the box. You ll need this v v v v
