This issue is often due to a failing drive. So, let's check that first, because if it is failing, it would need to be replaced and there is no point then in doing anything else until we confirm that.

If your PC is new enough to support UEFI, you can use these steps to test the hard drive: http://support.hp.com/us-en/document/c00439024

If not, to check the drive you have to follow these steps:
1) Press Esc key repeatedly, several times a second, while rebooting the laptop. Do NOT hold the key down, just press it over and over.
2) Eventually, you will see an HP Startup Menu
3) Press the Function key for testing the hard drive (usually F2) and let it run.

I know the boot device in the hard drive doesn't work. I've already ran the hard drive test.

You said nothing about having already run the test -- so how are we here supposed to know that?

You would have to replace the drive.

Once you have the drive, read the information on HP Cloud Recovery to create media needed to restore your PC:

If your PC is a 2016 model or newer, you should see if you can make a bootable USB recovery drive using the HP cloud recovery tool on a working PC.

The recovery drive can then be used to install Win10 and the HP drivers and utilities that originally came with your PC.
