If performing a Reset this PC does not work and most methods fail, you may need to consider performing a Clean Installation of Windows 10.
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.
