Normally when that error is reported, the hard drive is missing the operating system.

How to fix this issue

You can reinstall W10 by making a bootable USB installation flash drive with the Media creation tool from the link below.

You appear to be the same person who asked for help with clearing a BIOS password.

If this request was in reference to your HP 8440p notebook, it is very possible that the PC may not allow you to boot from a USB flash drive or DVD to reinstall Windows and in that event, unfortunately, you are out of luck.
