After successful update from Windows 10 Pro Build 10240 to Build 10586 (november upgrade) pc just start rebooting constantly on boot logo.
I can't choose "Safe Mode" option on boot.
With Windows 10 installation media I have used option "Go back to the previous build"... to revert failed upgrade to previous version.
Any ideas how to upgrade current installation without full reinstall process?
Same issue at Microsoft Community.
Thanks
Clean install is the only way to do the upgrade. – Sergey L – 2016-01-11T11:38:40.930
