Difficulty: HardMicrosoft Command-Line Tools

A Tier 2 support technician is troubleshooting a Windows workstation that fails to start, displaying the message 'Boot Configuration Data is missing or contains errors.' The technician boots into the Windows Recovery Environment (WinRE) Command Prompt and needs to perform a full scan of all connected storage drives for compatible Windows installations, while also interactively prompting to rebuild and add missing installations to the BCD store. Which command and switch combination should the technician execute?

  1. bootrec /rebuildbcdAnswer
  2. B
    bootrec /scanos
  3. C
    bcdedit /export C:\BCD_Backup
  4. D
    fsck -r /boot/bcd

Answer

The command `bootrec /rebuildbcd` is the correct selection.
Executing `bootrec /rebuildbcd` scans all attached disks for Windows installations compatible with Windows 10/11 and allows the administrator to manually select which detected operating systems to add to the BCD store, successfully restoring boot functionality.

Step-by-Step Solution

1
Identify the primary recovery objective from the scenario.
The technician needs to locate missing Windows installations across all disks and interactively add them to repair the missing or corrupted Boot Configuration Data (BCD) store.
Resolving BCD startup failure requires updating the BCD database entries with detected OS installations.
2
Evaluate the capabilities of bootrec recovery switches.
While `bootrec /scanos` identifies compatible operating systems without modifying the BCD, `bootrec /rebuildbcd` actively scans all drives and gives the administrator the choice to rebuild the BCD entries.
Selecting the interactive rebuild switch ensures complete remediation of missing boot entries.
