Windows 7: Windows 7 Build 7601 This copy of Windows is not genuine

My company bought about 15 pieces of desktop pc from dell.
I created an Windows 7 image using Dell pre-installed Windows 7.
I have used this image to clone 14 pieces of the dektops and there was no issue.
However, the last one I encountered "Windows 7 Build 7601 This copy of Windows is not genuine" when I powered on the machine. I don't even have any chance to login to windows to activate it by using its OEM Product Key. Please the screenshot as attached.
Please kindly advice any solutions to this issue.

Assuming you got machines with no OS how are you activating them, are you licensed to do so, it sounds like you have one copy of windows and are trying to run it on multiple machines
Post an MGAdiag report of one of them and we can take a look

Yes, we created a standard image to clone to multiple machine of same model. Very strange this issue only happen on that only machine.

First try Control-Alt-Delete to open the task Manager, click New task, then type CMD in Run box.

In Command Prompt type slmgr -ipk followed by a space and the Product ID, press Enter then slmgr -ato to attempt activation. Reboot.

If that fails it could be non-geniune lockout caused by a drive letter change in registry which happens sometimes during reimaging or repartitioning.

Boot the Paragon CD - select Normal Mode , then Boot Corrector.

Correct drive letters in the system registry.



Release the incorrect letter first, if necesssary.

If this fails you'll need to reimage this time selecting Auto for drive letter.

Please run the MGADiag report - if you used either the OEM_SLP Key, or a KMS Key for the build, there's probably a very simple explanation (a broken SLIC table in the machine's BIOS)
