Hi, good day!
The best thing to do in this situation is to perform a Clean Install of Windows 10. However, you will need to find another working Windows computer from a family member or friend near you to create the Windows 10 USB Installation media.
Find another working computer then download the Media Creation tool (Click Download tool now). Use the tool to "Create installation media (USB flash drive at least 8GB in size) to install Windows 10". Instructions inside the link.
Note: Please make sure to uncheck the "Use the recommended options for this PC" box. Please check the link below for more details.

Insert the USB Installation media into your computer. Please change the boot order in the Bios Settings. Boot your PC from the Installation Media you created.
Kindly refer to the link below on How to Perform a Clean Install for more details.
