My MacBook Pro will not Boot. It gets halfway through the process, then completely shuts down.

What do I need to do to boot my MacBook Pro? I ran a utility and received an error: Cannot load 'EFI/Drivers/TestSupport.efi'

MacBook Pro 15″, macOS 10.13

Thanks. In that case, please refer to if your Mac starts up to an Apple logo or progress bar and proceed with the steps following Step 4.
