If you’re running in PowerShell (where the prompt has the word “PS”), then you need to provide a relative or full pathname for the batch file.
Code: 
.\Repair_My_BootWIM.bat E:

I am using the CMD Command Prompt.
Should I enter it into this path?
if ($args.Count -eq 0) {
'Usage: Repair_My_BootWIM.bat [DriveLetter]'

1. Extract or save the batch to a folder.
2. From your command window, "cd" into that folder.
3. Run ".\Repair_My_BootWIM.bat D:"

In this example, you've already prepared an USB thumb drive that boots. And it's plugged in as drive letter D:

You're not supposed to edit the batch file. The script is supposed to accept whatever drive letter is provided on the command line.

I ran Repair_My_BootWIM.bat as an administrator.
Without editing it.
And the error persists, just like before switching to the new Repair_My_BootWIM.bat.
