So I have reinstalled windows 7 many times but never on a brand new drive. I would always just wipe the partition and install clean. Now for the first time I am installing on a brand new SSD and I am unable to activate it. I get the error that the version is for upgrade only, no clean installs. What's the easiest way for me to fix this? I can't install XP first as I have no idea where the disc is and don't want to waste the time. Do I have to call them and explain my situation? I did not format my old drive with the OS on it, will doing that somehow allow me to validate this copy? Thanks in advance for the help!
