To fix this error, do any of these fixes.

<strong>Fix #1: Hard disk cables</strong>

Make sure all your hard disks cables are connected properly.

<strong>Fix #2: Run chkdsk /f /r</strong>

You can access the Bootrec.exe utility with a Windows 7 installation disk:

<p class="info">If you don't have the installation disk, <a href="https://neosmart.net/EasyRE/">use Easy Recovery Essentials to rebuild the BCD.</a></p>
