Ok, I am not exactly illiterate when it comes to PC stuff, but I wanna double check to make sure this will work before I go all commando and do it. I do not want a duel os, just a single being the Professional. I found something in a similar thread but wanted to make sure it would work for my system switch as well. I wish to switch my operating system from XP Home to XP professional, from what I have read so far, all I would need to do is wipe out the home partition and replace it with the Professional partition, correct? If there is something I am missing, please let me know. Thanks in advance.
