I am trying to install windows xp sp3 on a computer from the cd. Through setup I deleted the existing partitions and made a new one. When I hit enter it says that this is not a windows xp compatable partion please go back and make a new one. I've installed windows this way many times before and I remember it is supposed to give you the option to format and then you can install but for some reason it won't do it. I've tried two different copies of windows and I formated the drive in another pc in NTFS and I still get the same message.
