Difficulty: EasyTroubleshooting Windows OS Startup and Boot Errors

A technician is troubleshooting a Windows workstation that fails to boot, displaying error code 0xc000014c with a message indicating that the Boot Configuration Data (BCD) file is missing or contains errors. The technician boots the computer into the Windows Recovery Environment (WinRE) and opens the Command Prompt. Which of the following commands should the technician execute to scan for installed operating systems and rebuild the BCD repository?

  1. bootrec /rebuildbcdAnswer
  2. B
    bootrec /fixmbr
  3. C
    sfc /scannow
  4. D
    chkdsk /r

Answer

The command bootrec /rebuildbcd scans all connected storage drives for installed Windows operating systems and allows the technician to rebuild the Boot Configuration Data (BCD) store.
Executing bootrec /rebuildbcd searches all mounted storage volumes for Windows installations and allows the user to rebuild the Boot Configuration Data store, directly resolving BCD corruption errors such as 0xc000014c.

Step-by-Step Solution

1
Analyze the boot error symptom code 0xc000014c.
Identified that the system cannot locate or read the Boot Configuration Data (BCD) file.
Error 0xc000014c specifically indicates missing or corrupted BCD information.
2
Boot into the Windows Recovery Environment (WinRE) Command Prompt.
Opened an offline command line interface with administrative recovery utilities.
Boot environment files cannot be modified while the standard operating system is active or failing to load.
3
Execute the utility command bootrec /rebuildbcd.
The utility scans the disk partitions for Windows installations and prompts to re-add them to the BCD repository.
This process constructs a clean BCD store, enabling Windows Boot Manager to start the operating system.
