Help with Boot Camp!

So I'm really new at this and can't find a tutorial out there to help me with this but here it goes.

I used Boot Camp to create a partition for Windows Vista and put the disc in to install the OS then when trying to install after it rebooted..it said something like "needs to be NFTS format" but my main question is, how can I format the partition I'm installing Windows Vista on to be NFTS format (with Boot Camp)?

Thank you
