Windows 7 to Windows 10 error 0xc000000f


So has there been any resolution to this besides getting a new key from Microsoft? I am experiencing the same issue as others. There is no option for turning off secure boot and I only have ACHI and compatibility, I have tried to upgrade several times, all result in the 0xc000000f error. I have a Lenovo L420. A clean install works perfectly fine but as others have said this causes Win 10 to stays inactivated. I am able to get all the way through the first 2 steps where the computer restarts and about 60% way through copying, aprox 20% overall, at the installation screen the laptop will restart and I get the message 0xc000000f, A required device isn't connected or cannot be accessed. Any help is greatly appreciated.

Lenovo L420, clean 7 install ---> 10 upgrade
