1. I have both the Windows XP Home Edition CD that came with the computer, and also a Windows XP Professional Upgrade CD that I purchased. Should I just use the Professional one when re-installing, or should I install the Home Edition, and then Upgrade to Professional after Home Edition is installed?
2. In my Dell Solutions Guide book, it says: "NOTICE: The operating system CD provides options for reinstalling your Windows XP operating system. The options can potentially overwrite files installed by Dell and possibly affect programs installed on your hard drive. Therefore, Dell does not recommend that you reinstall your operating system unless instructed to do so by a Dell technical support representative."
2a. Are those files important? What will happen if I overwrite them? Where are these options at? Shouldn't the Windows XP CD have everything I need to make the computer work correctly?
2b. I don't understand what this means. How will it affect programs installed on my hard drive?
