My PC shut down during a windows update due to power failure, now a w

"Hi,

If you have Win 10 installed try to get into the WRE (Windows Recovery Environment) menu area.

To do this, turn off the laptop and then start it again. Once it starts allow it to start to boot into Windows and then force stop the laptop by holding the power button until it shuts down.

Do this procedure 3 times, i.e. start > boot > shutdown, start > boot > shutdown. On the 3rd attempt it should boot into the WRE.

Once there select Troubleshoot > Advanced > Start up Repair and follow the prompts.

Do not select Reset your PC as this will erase all your data and reinstall Windows.

If this doesn't work use the same procedure and try to restore your pc using a system restore point or a system image (if you have them that is)

If you haven't got a WRE for whatever reason on your laptop, you can create a Windows 10 Recovery USB from any known working Win 10 computer. You'll need an empty 8GB flashdrive and about 60 minutes of time to do this. In the computer go to Control Panel > Recovery. When you have created the USB drive, plug it into the laptop and then alter the boot options in the laptop (usually press F12 on startup) to boot from the USB first. It will load the WRE and you can try the startup repair as mentioned before."

I think I shouldn't left my laptop even I'm just a minute stirring up my coffee, I am rebooting my laptop with Win 10 (O.S) when suddenly after I get back, my screen was went black. What could be happening onto this? I should’ve have just reboot my laptop to a professional, than doing it on my own. Why should I do? Please help
