220-1102 Software Troubleshooting Practice Question
A technician is troubleshooting a Windows 10 system that fails to boot with the error: 'STATUS_BAD_IMAGE_INFO'. The technician suspects the Boot Configuration Data (BCD) store is corrupted. The technician booted into the Windows Recovery Environment (WinRE). Which command should the technician use to rebuild the BCD store?
⚠ Common exam trap
Watch out — candidates often confuse `bootrec /rebuildbcd` with `bcdedit /import`, mistakenly thinking that importing a default BCD is equivalent to rebuilding, when in fact `/import` requires a prior export and does not scan for existing installations.

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 /rebuildbcd
The `bootrec /rebuildbcd` command scans all disks for Windows installations and prompts the user to add any found installations to the BCD store, effectively rebuilding a corrupted or missing BCD. Since the technician has already booted into WinRE and suspects BCD corruption, this is the correct tool to repair the boot configuration without manually editing entries.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
bootrec /rebuildbcd
Why this is correct
bootrec /rebuildbcd scans every fixed disk for Windows installations and then offers to add each detected installation to the Boot Configuration Data (BCD) store. Running this from the Windows Recovery Environment command prompt is the correct way to reconstruct a missing or corrupted BCD, because it recreates boot entries rather than relying on an existing backup. However, it does not repair bootmgr itself or fix partition-level problems, so it should be paired with /FixBoot and /FixMbr when needed.
- ✗
bcdedit /import
Why it's wrong here
bcdedit /import path merges or replaces the current BCD store with a previously exported .bcd file, which means it restores a snapshot rather than discovering current installations. If no export was made before the failure, there is nothing to import, so this command cannot re-create entries from scratch. It is therefore a recovery-and-restore tool, not a rebuild tool, and it will not help when the store is absent or was never backed up.
- ✗
sfc /scannow
Why it's wrong here
sfc /scannow verifies the integrity of all protected operating system files by comparing them with cached copies and replacing any corrupted versions it finds. The BCD store is not one of the system files that System File Checker validates in this way, so a damaged or missing BCD remains untouched even after a successful scan. This command is valuable for repairing system DLL or driver corruption, but it cannot append boot entries or regenerate boot-loader configuration.
- ✗
chkdsk /f
Why it's wrong here
chkdsk /f locks the volume and checks its file-system metadata, scanning for bad sectors, cross-linked files, and other structural disk-integrity errors, then attempts repairs. Although disk corruption on the boot volume can stop Windows from starting, the command is not aware of boot configuration entries and does not modify or recreate the BCD. It should be used to rule out or repair physical/format-level problems, not as a solution for missing or invalid boot configuration data.
