Tiger to Leopard... Need to re-install Windows Partition?

Hi everyone,

I'm running Tiger right now and I am going to buy Leopard soon. Judging from all the problems people are having. I have decided I am going to do an Erase and Install. However, I'm running Boot Camp under Tiger right now. If I do an Erase and Install, will that effect my current Boot Camp partition? Do I need to re-install Windows again or will Leopard see that its a separate partition and leave it in tack?

Thanks
