  2. When you see the Windows Recovery Environment screen, click on the "Advanced Startup" option.
  3. Click on the "Command Prompt" option.
  4. At the command prompt, type the following commands: bcdedit /set {current} recoveryenabled true bcdedit /set {current} restorepointpath "C:\Recovery" bcdedit /set {current} bootstatuspolicy ignoreall bcdedit /set {current} bootstatuspolicy enableall bcdedit /display {current}
  5. When you are finished, type the following command to exit the Recovery Environment: exit

2. Use the Command Prompt to run the Bootrec.exe tool

  1. Open the Command Prompt by clicking on the Start button, typing in cmd and pressing Enter.
  2. When the Command Prompt opens, type in bootrec and press Enter.
  3. Bootrec.exe will open and you will be given a list of available options.
  4. Choose the "Fix Boot Problems" option and press Enter.
  5. Bootrec.exe will scan your computer for boot problems and offer solutions.
  6. If Bootrec.exe finds a boot problem, it will offer to fix it. Follow the instructions it provides.

3. Use the Command Prompt to run the Sfc.exe tool

  1. Open the Command Prompt and type "sfc /scannow"
  2. If the Sfc.exe tool finds any errors, it will display the error code and the name of the file that has the error.
  3. If the Sfc.exe tool cannot find the file that has the error, it will display an error message.

If the answers above didn't work then you should also try:
