However, it may also indicate that the hard drive has failed and needs to be replaced.

- Run Automatic repair – no go.
- Run the troubleshooter – can’t.
- Run SFC scan – no go.
- Make sure UEFI is active – check.
- Check for lose cables – check.
- Disconnect USB peripherals – check.
- Set the hard drive as first boot device – already set.
- Try to fix the MBR – can’t read drive to fix MBR
