A driver update should be a good thing, not something that caused you headaches like this.
From what I can tell you have done a large amount of troubleshooting on your own, and the big issue here is about why you cannot system restore and if you repair from usb or optical drive bootable.
Have you created any recovery media on a disc or USB?
yes, I did create a bootable recovery disc on USB. Tried with both bootable DVD and USBs, but nothing worked.
Also from the command prompt(in recovery screen), I tried to change the bootmenu policy(to get to safe mode and uninstall the Nvidia driver) using bcdedit tool, but everytime I ran any of the the following command it gave me the same error msg:
bcdedit /set {default} bootmenupolicy legacy
The boot configuration data store could not be opened.
