I purchased Dell Latitude E6500 in Oct. 2009. Vista was installed, disks for both Vista and XP were part of the package. A short time later I received an offer from Dell to purchase "Windows 7 Upgrade Option from Dell P/N 747C1" for a nominal amount of money. I received the Win 7 disk with the Microsoft Proof of License Certificate of Authenticity attached. Under the Microsoft details on the right side of the certificate is the number: X15 - 53890.
The Dell disk "Windows 7 Upgrade Option, Windows Vista Business to Windows 7 Professional had two install options: Upgrade from Vista and Clean install. I chose the clean install. Installed it dual boot with WinXP. Both OS worked fine.
Last night 14.06.26 the Windows auto update downloaded and installed additional files. This morning Win 7 will not boot. A note says: Not Genuine Copy.
I have a Macrium Clone of the Win7 partition that was made several days ago, when Win7 was working.
How do I correct this "not genuine" condition?
