New HDD install problems

I'm trying to install a new hard drive in pc that was previously upgraded from vista to w7 with upgrade disc. I am able to get windows to load but when i get to the product key portion it wont take it. It says retype key. Will I have to install vista and then re-upgrade with the disc?

You could try cloning the old drive to the new?
