4. Press F10 to Save and Exit.

5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?

If the issue persists, run a Hard drive test to confirm the Hardware Functionality

- Hold the power button for at least five seconds to turn off the computer.
- Turn on the computer and immediately press Esc repeatedly, about once every second. 
- When the menu appears, press the F2 key.
- On the main menu, click Component Tests and Hard drive

Keep me posted how it goes
