Why can't I upgrade to Windows 10?

Episode 1241 (35:56)

Michael from Santa Clarita, CA

Michael bought a Dell computer from Costco running Windows 7. Now he wants to upgrade to Windows 10 and he can't seem to do it. He's been told that the BIOS thinks it's running Windows 8.1 doesn't recognize Windows 7. Leo says he can try running the Windows 10 ISO directly. Michael says he's tried that, but it didn't work. Now Dell wants him to install a new motherboard. Leo says he should take Windows 8.1 recovery disks and get it back to the day it came from the store with Windows 8.1. Then try and Windows 10 upgrade. It should work after that.
