I was recently trying to upgrade to Windows 10 and was using my copy of Windows 7 upgrade media to do it. I have a license for XP full and wanted to just use 7 and go straight to 10. I of course had difficulty because Microsoft makes it hard to use upgrade media for a full install. I found the article below and using method #2 I was able to make it work. I am just passing along the helpful information should someone else run into the same issue. I found the information at the following link.
