When you reinstall Windows, it will automatically delete ALL of the files on your computer no matter which disk you use. Be Careful!
Make sure that you backup all of your necessary files before you reinstall. You will also need to reinstall ALL your software after you install Windows, so make sure you have those disks.
Also, make sure that you have copies of all your device drivers before you reinstall Windows. This is especially important for your network card. If you do not have the drivers for your network card on disk, you will NOT be able to connect to the internet in order to download them.
If you can not even boot into Windows at the moment (making it impossible to backup your files), I recommend using a Linux LiveCD to gain access to your files (see
http://www.ubuntu.com ).
