2. Restart your computer and boot from the disc
3. Press any key when the “Press any key to boot from CD or DVD” message appears
4. Select Repair your computer after you select your language, time and keyboard method preferences
5. Select your Windows installation drive (which is usually C:\) and click Next
6. Choose Command Prompt when the System Recovery Options box appears
7. Type in this command:

   bootrec /rebuildbcd

8. Press Enter
9. Wait for the process to wait, remove the disc and restart your computer
