- A
System File Checker (sfc /scannow)
Why wrong: SFC repairs corrupted system files but does not fix boot configuration issues like a missing BCD.
- B
Bootrec (bootrec /rebuildbcd)
Bootrec is specifically designed to repair boot-related issues, including rebuilding the BCD store.
- C
DISM (DISM /Online /Cleanup-Image /RestoreHealth)
Why wrong: DISM repairs the Windows image but cannot be run offline without specifying a source; it does not directly fix boot configuration.
- D
Diskpart (diskpart /s script.txt)
Why wrong: Diskpart manages disks and partitions but does not repair boot files.
220-1202 Windows OS Features and Tools Practice Question
This 220-1202 practice question tests your understanding of windows os features and tools. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician is troubleshooting a Windows 11 computer that fails to boot with a 'Bootmgr is missing' error. They have a Windows installation USB. Which tool from the Windows Recovery Environment should they use to repair the boot configuration data (BCD)?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Bootrec (bootrec /rebuildbcd)
The 'Bootmgr is missing' error indicates that the Boot Configuration Data (BCD) store is corrupted or missing. The `bootrec /rebuildbcd` command scans all disks for Windows installations and rebuilds the BCD store from scratch, directly addressing the missing or corrupted boot configuration. This is the correct tool in the Windows Recovery Environment for repairing BCD issues.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

System File Checker (sfc /scannow)
Why it's wrong here
SFC repairs corrupted system files but does not fix boot configuration issues like a missing BCD.
- ✓
Bootrec (bootrec /rebuildbcd)
Why this is correct
Bootrec is specifically designed to repair boot-related issues, including rebuilding the BCD store.

DISM (DISM /Online /Cleanup-Image /RestoreHealth)
Why it's wrong here
DISM repairs the Windows image but cannot be run offline without specifying a source; it does not directly fix boot configuration.
- ✗
Diskpart (diskpart /s script.txt)
Why it's wrong here
Diskpart manages disks and partitions but does not repair boot files.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse `bootrec /rebuildbcd` with `sfc /scannow` or `DISM`, thinking any 'repair' tool can fix boot issues, but only `bootrec` specifically targets the BCD store required for the boot manager to locate the Windows loader.
Detailed technical explanation
How to think about this question
The BCD store is a firmware-independent database located at `\Boot\BCD` on the active partition (or the EFI System Partition on UEFI systems). The `bootrec /rebuildbcd` command scans all disks for Windows installations, prompts the user to add each found installation to the BCD, and regenerates the store; if the BCD is completely missing, it creates a new one. In contrast, `bootrec /fixboot` and `bootrec /fixmbr` repair the boot sector and master boot record, respectively, but do not rebuild the BCD store itself.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
