Difficulty: MediumMicrosoft Command-Line Tools

A Windows 11 workstation fails to start, displaying an error message indicating that the Boot Configuration Data (BCD) file is missing or corrupted. A technician boots the workstation into the Windows Recovery Environment (WinRE) Command Prompt. Which of the following commands should the technician execute to scan all connected disks for installed Windows operating systems and rebuild the BCD store?

  1. bootrec /rebuildbcdAnswer
  2. B
    bootrec /fixmbr
  3. C
    bootrec /fixboot
  4. D
    grub-install /dev/sda

Answer

bootrec /rebuildbcd
The command 'bootrec /rebuildbcd' scans all connected disks for operating system installations compatible with Windows and gives the technician the option to rebuild the BCD store by adding detected installations.

Step-by-Step Solution

1
Identify the specific boot failure symptom described in the scenario.
The system reports missing or corrupted Boot Configuration Data (BCD).
Understanding the exact failure component determines which command-line switch or utility is required.
2
Evaluate the function of the bootrec utility switches available in WinRE Command Prompt.
The switch /rebuildbcd explicitly searches all connected hard drives for compatible Windows installations and prompts the user to add them to the BCD store.
Rebuilding the BCD store directly restores missing boot entries required for Windows startup.
