I am about to install parallels into my Macbook pro. I understand I need to re-install my windows XP. Do I also have to re-install all the programs on the windows side of my Macbook as well? I have quite a number of them including Adobe CS3 and Quickbooks.....
If you mean by "windows side of my Macbook" the Boot camp partition, there is no need to reinstall neither Windows nor Windows programs. All you need is to create a virtual machine based on Boot camp partition: http://download.parallels.com/desktop/v4/docs/en/Parallels_Desktop_Users_Guide/22437.htm
