220-1102 Practice Question: A technician is troubleshooting a Windows 10…
This 220-1102 practice question tests your understanding of a technician is troubleshooting a windows 10…. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: bootrec is a command-line tool for repairing boot problems.. 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 workstation that fails to boot with the error 'Bootmgr is missing'. The technician has booted from a Windows 10 installation media and opened a command prompt from the recovery environment. Which built-in command-line tool should the technician use to repair the Master Boot Record (MBR) for the system partition?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
bootrec /fixmbr
This command writes a new MBR to the system partition, which is the first step to resolve bootmgr missing errors caused by MBR corruption.
B
Distractor review
sfc /scannow
This command scans for and repairs protected system files, but does not repair the MBR or boot sector.
C
Distractor review
chkdsk /f
This command checks for file system errors and bad sectors, but does not address MBR corruption.
D
Distractor review
bcdedit /rebuildbcd
While this command rebuilds the BCD store, it is not the first step when the bootmgr is missing; the MBR should be fixed first.
Answer analysis
Why the other options are wrong
Understanding why incorrect options are tempting is as important as knowing the correct answer.
- ✗
sfc /scannow
This command scans for and repairs protected system files, but does not repair the MBR or boot sector.
- ✗
chkdsk /f
This command checks for file system errors and bad sectors, but does not address MBR corruption.
- ✗
bcdedit /rebuildbcd
While this command rebuilds the BCD store, it is not the first step when the bootmgr is missing; the MBR should be fixed first.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Candidates might be tempted by `bcdedit /rebuildbcd` as it also relates to boot issues, but it's not the correct first step when the MBR is missing.
Technical deep dive
How to think about this question
The 'bootmgr is missing' error indicates a problem with the boot sector or the Master Boot Record (MBR) on the primary hard drive, preventing the system from locating the Windows Boot Manager. The `bootrec` command-line tool, specifically with the `/fixmbr` switch, is designed to write a new MBR to the system partition without overwriting the existing partition table. This process essentially repairs the foundational boot information that the BIOS/UEFI firmware uses to hand off control to the operating system's boot loader. In this scenario, since the technician has already accessed the Windows Recovery Environment (WinRE) and a command prompt, `bootrec /fixmbr` is the direct and appropriate first step to address the MBR corruption that is likely causing the 'bootmgr is missing' error. It establishes the correct starting point for the boot process. While other commands like `bcdedit /rebuildbcd` are related to boot issues, they operate at a different level. `bcdedit /rebuildbcd` rebuilds the Boot Configuration Data (BCD) store, which contains information about installed operating systems and boot options. However, if the MBR itself is corrupted, the system cannot even find the BCD store. Similarly, `sfc /scannow` checks and repairs protected system files within the Windows installation, and `chkdsk /f` checks for and fixes file system errors and bad sectors on a volume. Neither of these addresses the fundamental MBR corruption that prevents the system from initiating the boot process in the first place. Therefore, `bootrec /fixmbr` is the targeted solution for the described error.
KKey Concepts to Remember
- bootrec is a command-line tool for repairing boot problems.
- /fixmbr writes a new Master Boot Record to the system partition.
- It does not overwrite the existing partition table.
- Used when the MBR is corrupted or missing, causing boot failures.
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
bootrec is a command-line tool for repairing boot problems.

FAQ
Questions learners often ask
What does this 220-1102 question test?
bootrec is a command-line tool for repairing boot problems.
What is the correct answer to this question?
The correct answer is: bootrec /fixmbr — The 'bootrec /fixmbr' command writes a new Master Boot Record to the system partition, which is appropriate when the bootmgr is missing due to a corrupted MBR. 'sfc /scannow' checks system file integrity, 'chkdsk /f' fixes disk errors, and 'bcdedit /rebuildbcd' rebuilds the Boot Configuration Data, but the 'Bootmgr is missing' error often requires fixing the MBR or boot sector first.
