A technician is troubleshooting a Windows 11 device that consistently fails to boot, displaying a 'Your PC ran into a problem' error with various stop codes. The technician suspects a corrupted boot configuration data (BCD) store. Which command-line utility, accessible from the Windows Recovery Environment (WinRE), should the technician use to repair the BCD?
- Achkdsk
- Bbootrec
- Cdism
- Dsfc
Show answer & explanationAnswer & explanation
Correct answer: B. bootrec
The `bootrec` command-line utility is specifically designed for troubleshooting and repairing boot-related issues, including rebuilding or repairing the Boot Configuration Data (BCD) store in Windows.
Why the other options are wrong
- A. chkdsk checks and repairs file system errors on a disk, not specifically BCD issues.
- C. dism (Deployment Image Servicing and Management) is used for servicing Windows images, not for direct BCD repair.
- D. sfc (System File Checker) scans and repairs corrupted Windows system files, not the BCD.
bootrec command
A command-line tool available in the Windows Recovery Environment (WinRE) used to troubleshoot and repair master boot record (MBR), boot sector, and Boot Configuration Data (BCD) issues.
- Commonly used with options like /FixMbr, /FixBoot, /ScanOs, and /RebuildBcd.
- Essential for resolving boot failures caused by corrupted boot data.

Memory trick: Bootrec gets your boots (boot-up) back on track.
