Steps to  repair the boot sector in Windows 10:

  • Make a bootable USB disc for Windows 10.
  • To start from the bootable media, change the device firmware settings.
  • The bootable disc should be used to start the computer.
  • In the Windows 10 Setup, click the Next button.
  • In the lower-left corner, click the Repair your computer icon.
  • Select Troubleshoot from the drop-down menu.
  • Select Advanced settings from the drop-down menu.
  • Select Command Prompt from the drop-down menu.
  • You'll now be in the Command Prompt environment, where you may use the Bootrec.exe utility to repair the Master Boot Record on your Windows 10 computer. Depending on your situation, the Bootrec.exe command utility offers a variety of alternatives.
  • When you need to repair Master Boot Record corruption issues or clean the code from the MBR, use the FixMbr option. This command will not overwrite the hard drive's existing partition table.
  • If investigating the 'Bootmgr Is Missing' error and rebuilding the BCD store does not resolve the issue, use the following instructions to export and wipe the BCD store before reinstalling Windows 10.
  • To add Windows 10 to the list of bootable operating systems on your device, press Y.
  • Command Prompt should be closed.
