Difficulty: MediumTroubleshooting Windows OS Startup and Boot Errors

An IT technician is troubleshooting a Windows workstation that crashes with a stop error (BSOD) during the boot sequence immediately following a recent driver update. Automatic Repair is unable to fix the issue, and normal boot fails consistently. The technician opens the Command Prompt inside the Windows Recovery Environment (WinRE) to isolate and disable the problematic driver. Which of the following commands should the technician execute to configure the Operating System to launch into Safe Mode on the next system restart?

  1. bcdedit /set {default} safeboot minimalAnswer
  2. B
    bootrec /rebuildbcd
  3. C
    sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
  4. D
    dism /online /cleanup-image /restorehealth

Answer

Execute the command 'bcdedit /set {default} safeboot minimal' from the WinRE command prompt to force Windows into Safe Mode on the next boot.
Configuring the BCD store with 'bcdedit /set {default} safeboot minimal' forces the OS to start in Safe Mode. Safe Mode loads minimal essential drivers, allowing the technician to access Device Manager or Apps & Features to roll back or remove the malfunctioning third-party driver.

Step-by-Step Solution

1
Identify the troubleshooting goal in WinRE
The goal is to force the workstation into Safe Mode so third-party kernel drivers are bypassed during startup.
Safe Mode loads a minimal set of drivers and services, preventing the faulty driver from causing a blue screen.
2
Select the proper command-line utility for boot configuration settings
Use BCDEdit (Boot Configuration Data Editor) to modify boot parameters.
BCDEdit manages the boot settings store in modern Windows operating systems.
3
Apply the appropriate parameter switch
Run 'bcdedit /set {default} safeboot minimal'.
Setting the safeboot option to minimal instructs the bootloader to load the standard Safe Mode environment upon reboot.
