I would suggest doing a Windows 10 repair using the installation media. If you do not have the installation media you can use the Media Creation Tool
to create Windows 10 installation media for a disc or flash drive.
There are three options, use the second option Using the tool to create installation media (USB flash drive, DVD, or ISO file) to install Windows 10 on different PC
Once you have the installation media you will need to change the boot order in the BIOS/UEFI so that the disc or flash drive are listed as the first device in the order, the hdd/ssd the second device. If you are using a DVD you will want to make the first device the CDROM, if it is a flash drive you will want to make the USB device the first device.
Once you have the installation install in the computer restart it.
You should receive as message instructing you to press any key to continue, do so.
Once the installation begins you will go through a number of steps. When you see the image below select Repair your computer

This will take you to the System Recovery Options
, select the Startup Repair
. This will run the repair after this.
