I have purchased a new Lenovo H30 PC based on the recommendations from this site. The PC came with Windows 10 Home. I have a license key for Windows 7 Professional. I understand that I can upgrade to Windows 10 Professional with the license. However, when I attempt to upgrade I get the error shown in the image.
Can someone let me know the correct to upgrade. I'm hoping I don't have to do a complete re-install of Windows 7 Professional to upgrade.
