Hi there,

Possible reasons for this error are:

-bios did not detect your hard drive or the hard drive is damaged

solution is to reset the bios by removing the rtc battery or by loading default settings,save and exit.then restart your machine,boot from recovery console and repair windows.link below will guide you:


Or replace the hard drive as it may not have passed (hal) during boot process.
