The answer is the Command Prompt, used to run bootrec /rebuildbcd from the Windows Recovery Environment (WinRE). This is correct because when Bootmgr is missing, the Boot Configuration Data (BCD) store is often corrupted or missing, and bootrec.exe directly scans for Windows installations to rebuild that store, restoring the boot loader chain. On the CompTIA A+ Core 2 220-1202 exam, this scenario tests your ability to differentiate between WinRE tools: while Startup Repair can fix some boot issues, it does not manually rebuild the BCD, and System Restore rolls back system files without addressing boot configuration corruption. A common trap is choosing Startup Repair because it sounds similar, but the question specifically asks for the tool to repair the boot configuration, not just fix boot errors. Remember the memory tip: “Bootrec rebuilds the BCD, not just repairs the screen you see.”
220-1202 Windows Administrative Tools Practice Question
This 220-1202 practice question tests your understanding of windows administrative 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 10 PC that fails to boot with a 'Bootmgr is missing' error. They need to repair the boot configuration. Which administrative tool should be used from the Windows Recovery Environment (WinRE)?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Command Prompt to run bootrec /rebuildbcd.
The Command Prompt in WinRE allows running bootrec.exe and bcdedit.exe to repair the boot configuration. System Restore and Startup Repair are also in WinRE but do not directly rebuild the BCD. The other options are not available in WinRE.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
System Restore to revert to a previous restore point.
Why it's wrong here
Incorrect. System Restore may not fix the boot manager if the BCD is corrupted.
✓
Command Prompt to run bootrec /rebuildbcd.
Why this is correct
Correct. The bootrec command can rebuild the Boot Configuration Data (BCD) and fix the missing bootmgr error.

✗
Device Manager to update the disk driver.
Why it's wrong here
Incorrect. Device Manager is not available in WinRE, and disk drivers are not the issue.
✗
Local Security Policy to adjust boot options.
Why it's wrong here
Incorrect. Local Security Policy is not accessible in WinRE and does not manage boot configuration.

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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A customer complains that their Windows 10 PC fails to boot and displays a 'Bootmgr is missing' error. You suspect the Boot Configuration Data (BCD) is corrupted. Which tool should you use to repair the BCD from the Windows Recovery Environment?
easy
A.chkdsk /f
B.sfc /scannow
✓ C.bootrec /rebuildbcd
D.diskpart
Why C: The bootrec tool is specifically designed to repair BCD and boot sector issues. Running bootrec /rebuildbcd scans for Windows installations and rebuilds the BCD store.
Variation 2. A user reports that their Windows 10 PC fails to boot and displays a 'Boot Configuration Data is missing' error. You need to repair the boot configuration using the Windows Recovery Environment. Which administrative tool should you run from the command prompt in the recovery environment?
medium
A.sfc /scannow
✓ B.bootrec /rebuildbcd
C.DISM /Online /Cleanup-Image /RestoreHealth
D.chkdsk /f
Why B: Bootrec.exe is the command-line tool specifically designed to repair the Boot Configuration Data (BCD) and Master Boot Record (MBR). It is used from the Windows Recovery Environment command prompt. Other tools like SFC or DISM target system files or image health, not boot configuration.
