Installed new 500GB HDD, will not let me load any Windows. I installed a 500GB HDD on a HP PC for a friend, and I have an XP Home upgrade disk which XP Home was originally installed on the PC, and all I have is an upgrade disk so I tried to install Windows 2000, but it keeps failing on me and it even asked me to create a partition? I understand there may be issues with trying to use the full 500GB of the HDD, but I created a partition so is not letting me do an install?
