Error code 0xc000000f

I recently turned on my laptop and got a Recovery message. It says a required device isnt connected or cant be accessed. Error code: 0xc000000f. I have tried redownloading windows from a USB boot but havent had any success. I just keep getting the same message. Has anyone experienced this?

Yes -- and this is not a good sign.  It generally means that Windows has become so corrupted on your drive that although the boot loader can find the startup files, Windows still can not boot.  There is no simple way to repair this.

Also, this is most often caused by a failing drive -- as that corrupts Windows so it can't load anymore.

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.
If the drive checks out OK, then report that and I can provide you options for reinstalling Windows on your PC.

Thank you for replying. I have done as you said and run diagnostics on the hard drive and it has come back OK.
