Unmountable Boot Volume leads to Black Screen and unable to boot from usb.

[D00M]

Hello, the other night I was installing an anti virus and my laptop froze so I force shut it off. Upon it starting up, it took a very long time to get past the HP logo and when it did it led to the blue screen of death that read "UNMOUNTABLE BOOT VOLUME". I searched up the solution for this and installed the windows tool thing on my usb and selecting it so it's the first in the bios settings but it all still leads to a black screen. I enabled legacy mode, disabled secure boot and all that and even did a mixture but it still doesn't work. Its not a monitor issue, one of my files are corrupted. Recovery doesn't work. I dont know what to do and I'm out of ideas, would appreciate fast replies as I have to finish an assessment on time  and I cant do that without my laptop working.

Hi,

It could be a hardware problem such as the hard drive. So, first try performing HP hardware diagnostics on the Drive and system. Turn off the PC by holding power button. Turn on PC and continously press ESC until startup menu appears. Next press F2 to enter Hardware diagnostics and try the fast test.

You can also use the above procedure and then press F9 to get into boot menu to choose USB drive.

Let me know,

I did the System Fast Test and it all passed. The Hard Drive quick test also passed. And i tried doing the F9 boot menu thing too and that still leads to a black screen.

I just did a "System Extensive Test" and the "Hard Drive Optimised DST Check" came back as "Warning".

What is the Windows tool thing?

Did you download the media creation tool on a different PC, run and create a bootable pendrive with Windows 10 OS on it?

There is explanation on Microsoft support page on how to do this:

Yea the creation tool is what Im talking about, installed it directly and did it with an iso file too but the same result.

Did you use an application such as Rufus to transfer the iso image to the USB drive? (so that it is bootable)

[D00M]

Yeah i used rufus too. Same results

I still really need help, taking it back to the shops is my last resort.
