Hi guys. So I had a extra copy of Win 7 ultimate but the trial had run out. Now I always get a message when I run virtual/bootcamp saying "Windows 7 build 7601" telling me its not a legitimate copy. So, I recently purchased Win7 Pro for a bit cheap price. I would like to know if you can downgrade Win 7 through bootcamp? I have a disc and not the ISO. Sorry, I am not very familiar with Windows as much but I need it for work reasons. Thanks in advance.
