Will installing Snow Leopard screw bootcamp? Will upgrading Vista to 7 screw it up?

[oregon2]

I have a copy of Snow Leopard on the way and am wondering what I will have to do? Does you need to back up everything, or does it "dynamically" install? Either way, will I need to do anything to keep my bootcamp partition working?

On another note, I currently have Vista Ultimate in bootcamp and want to change to Windows 7. Is there a way to "upgrade"? Or will I have to clean install and rebootcamp?

Thanks!

Installing Snow Leopard did nothing to my VMWare set up or my Boot Camp partition.

It is all still working fine.

I don't expect your Win 7 upgrade will be a problem either, although there are no drivers for some Apple hardware under Win 7.
