HELP - Bootcamp

Hey everyone, I'm glad to have joined this forum.

The answer to my question is perhaps simple, but I just want to make sure there isn't another way out.

A couple of days ago I received a new Mac that I was very happy about, and installed Vista on a bootcamp partition. Eventually I found out that I didn't give Vista enough space, and that I wanted to divide the HD equally for Vista and Leopard.

So I deleted my Vista partition, since there is no way to just give the Vista HD more space, and now I wanted to just partition a whole new HD for Vista from scratch.

So I ran the bootcamp assist and it said it was partitioning the disc and then encounted that error where it says the disc is corrupted or something (I presume that you have all heard of the this error since most of my friends have had it, they all said it could only be fixed if you install a whole Leopard clean, and then run bootcamp[Which is what I did]). And that is my delemma.

So my question is, if I make a backup of my OSX (which I am doing currently), and start from scratch installing Leopard all over again etc. Will I be able to install my backup of my HD? Because I can see no way through this Bootcamp partition problem without just installing everything over again.
