I have formated my computer, which is a HP Pavillon not sure on the model number but, it did come with Windows XP Home Edition with a seperate modem for recovery, the question I have Is: After formatiing and re-installing Windows pro when I boot up it comes to a screen that actually ask me which version do I want to run... but the home edition doesnt work is that a branded processor or is there a way to get rid of that?
