Boot device not found 3F0

HP Recommended
Pavilion gaming 15
Microsoft Windows 10 (64-bit)

I was watching a video from a folder. Suddenly my laptop got stuck and it went black screen. After a few seconds it showed that 'Boot device not found' ,the error was 3F0 which shown on 3rd or 4th line below. I did hard drive check of both quick and extensive or something. It was all passed. But my problem did not solve. It shows the same error still.  Please help.

If your drive is OK, then the boot files got corrupted.

 

Windows PCs use two different sets of files to get you to a working desktop.
In terms of the first, Windows boot files, you need to follow the instructions below to create boot media from Macrium Reflect (MR) that can be used to rewrite/repair the boot media on your PC:
1) Download and install Macrium Reflect (MR) from this link on a working PC: http://www.macrium.com/reflectfree.aspx
2) Use the option to create a boot USB stick or CD

That will create MR bootable media. Then, you can boot your PC into WinPE using that media.

Have patience, as that can take a while to start and bring up the screen.

Once the screen is there, select the option to Fix Windows boot problems. It will then search for the OSs installed and list them, Select the one you want to repair and click Next.

It will now do the repairs, listing the things it has done.

When finished, select the option to Restart the PC.

If this worked, the boot repair succeeded and you will have your PC back.

But if it did not, the Windows system files are most likely corrupted and you would have to reinstall Windows from scratch to fix that.
