    Fault : "Automatic Repair couldn't repair your PC" -- the repair loop
    Fix   : Get past the driver that is failing
    Source: https://jbtecwiz.com/support/win-rec-autorepair-loop

    Run as     : WinRE startup settings
    Expect     : 45 minutes
    Risk       : medium
    Reversible : yes

    WHEN THIS IS THE RIGHT FIX
    New hardware or a driver update preceded it.

    HOW TO UNDO IT
    The removed driver package can be reinstalled from the vendor's
    download.

    This script walks the fix one step at a time and asks before each
    one. Steps with no command are things you do yourself -- it prints
    those and waits. Run with -DryRun to print without executing.
