I have just installed windows xp pro on to my computer it worked fine but now it needs to be activated. I have tried using the product key that came on the coa sticker with the disk but it will not work. The disk I have says it is a dell reinstall disk. I am lost now can anyone tell me does this make a difference. The computer i have put it on is not a dell and came with windows xp home on it but the reinstall disk that came with my system would not work. I have been told that I need to change the hard drive so that it is clean. Is this right. I have also been told to reformat the old hard drive and then reinstall the xp pro but I dont know how to do this.
Please help.
