Time Machine also copy Bootcamp?

Hello.

First of all, an overview:
Macbook Pro 13. HDD: 650 GB. Latest Snow Leopard. Mac experience: Some.

I'm trying to make a copy of my computer using Time Machine. I've been doing this before when I had my standard HDD, and it worked excellent. Since I bought a new HDD, I thought that I should make a new Time Machine copy. I've installed Windows 7 using Boot Camp, which got about 100 GB of the Harddrive. OSX got 550 GB (489 GB used). My external harddrive's space is just 500 GB.

When I tried to make a copy, it says that the external harddrive got too little space remaining, which is true if Time Machine also copy my Windows 7. (Another partition).

My question is, if I buy a new external HDD which got more than 650 GB space, will I be able to make a Time Machine copy of both my OSX and W7, and if my computer crashes in the future, will I just be able to plug the external harddrive in, and install the copy and it all looks like now? I know that OSX will, but will W7 also do it?

If the answer is not, how can I make that the Time Machine don't choose to copy the Windows partition? I can't do as I normal do.. Because you can't click on the partition and omit it. (please answer this question even if the answer is yes.)

Summary:
If I use Time Machine, will it also copy Windows 7 exaclly as it is right now? How can I uncheck to copy the windows partition?

Thanks in advance.
