Follow the steps mentioned below to perform Start up Repair:
a. Insert the installation DVD or USB and boot Windows 10 from it.
b. Select “Troubleshooting” from the first Window and then select “Advance Options”.
c. Then select “Automatic Repair” from “Advanced options” window.

This will help you to boot into your Operating system again.
