Perform an Automatic repair
The Automatic repair can detect and fix the issues that prevent the computer from working normally.
After you have a Windows 10 installation disc/USB, follow these steps:
When your computer starts, wait for the manufacturer logo to check the option for boot menu, it will usually be F12.
The boot menu key might differ with each manufacturer. If you are unable to find the boot menu key, you may refer the user manual.
Restart the computer, when the manufacturer's logo is displayed, keep pressing the Boot menu option key to enter the boot menu and change the boot option to CD\DVD ROM (in case you create DVD). Select USB in case you create USB.
After you boot your computer using Windows DVD or System Repair Disc, a black screen appears with gray text "Press any key to boot from CD or DVD". Press any key.
Select the correct time and Keyboard type.
Click Repair your computer in the lower left corner.
Click on Troubleshooting, advanced option and then click Startup Repair.
