Hello Vero83121.
I'm Daniel, an independent Advisor and I'll be glad to help you today.
One option is to try to go back to the previous build. I apologize if you have tried to do this. I would recommend resetting Windows 10 while keeping your files and applications.
To do this
- Start your PC while Windows tries to load and the spinning dots appear, press and hold the Power button for 5 to 10 seconds. This is known as forced shutdown
(do this twice)
- Turn on the computer a third time and it must be activated in the Recovery Environment
- You will be asked to enter System Repair / Safe Mode / Command Prompt
- Go to troubleshoot - advanced option - revert to the previous Windows build
- If unsuccessful, go to Troubleshooting - Advanced options - Reset this PC
Choose to keep your files and applications.
About the hard drive, I would recommend you to take it to an assistance to find out if it really stopped working or if there was a failure during the installation of Windows
