Black screen, PC won't start up

Product Name: Pavillion PC
Operating System: Microsoft Windows 10 (64-bit)

Windows 10 was downloaded.

PC was working ok for several weeks.

When tried to start PC one day, just left with a black screen and it said Windows was missing.


As Windows 10 was downloaded from internet it is not possible to reinstall it. 


Why would it disappear and how do I begin to rectify the problem?

Re: Black screen, PC won't start up




Allow me to welcome you to the HP forums!

I read your post about no boot device found and wanted to help.

These problems are generally due to one of two basic problems:
1) Failed hard drive
2) Corrupted/missing boot loader files

As to the first, please follow the directions in this link for testing your hard drive:

If that confirms your drive has failed, then you need to replace it.  Please report back if that is the case.

As to the second, you will need access to a working PC for this step in order to create the media needed to repair your PC boot loader.

Once you have that, please download and create Win10 install media from this link:

Note that when you go do download and build install media, the tool defaults to matching what is already installed on your PC (as in, Home for Home, 64-bit for 64-bit).  While you CAN change these settings, do NOT. If you do, the resulting media will be different and will force you to enter a NEW product code!

Boot from the media you created, and follow the directions in this link:

You will need to go to the Advanced Options screen and click on Startup Repair.  You will probably have to run Startup Repair three times for it to fix all the boot loader problems.

When done, your PC should boot OK.

Good Luck

Re: Black screen, PC won't start up

Thank you for your advice.


Upon checking the hard drive it would appear that a "drive replacement is recommended" :-(
