Youll need to use the Recovery Environment to get rid of this error.
This will help you boot into Recovery Environment.
Use System Restore
If the problem persists, go back toTroubleshoot, and selectAdvanced Options.
Select theSystem Restoreoption and verify if you have a restore point you’re free to go back to.
