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
✓
Startup Repair
The 'INACCESSIBLE_BOOT_DEVICE' error often indicates a driver or disk configuration issue caused by an update. The Startup Repair tool in the Windows Recovery Environment (WinRE) can automatically diagnose and fix common boot problems like this. It is the safest and fastest initial step before trying more invasive methods.
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
Why it's wrong here
System Restore reverts system files and settings to an earlier point, but it requires the OS to boot or access to WinRE. While it could fix the issue, Startup Repair is more targeted for boot errors and should be tried first.
- ✗
Reset this PC
Why it's wrong here
Reset this PC reinstalls Windows and can keep or remove personal files, but it is a more drastic step that should be reserved for when other repairs fail. It would erase installed applications and settings.
- ✓
Startup Repair
Why this is correct
Startup Repair is the most appropriate initial troubleshooting step for boot failures, especially after a Windows update, as it automatically diagnoses and attempts to fix common issues preventing the operating system from loading. It scans for corrupted system files, incorrect Boot Configuration Data (BCD), problematic drivers, and disk errors that might cause stop codes like INACCESSIBLE_BOOT_DEVICE. This automated tool is designed to restore boot functionality without requiring manual intervention in the command line, making it the primary first-response utility.
- ✗
Command Prompt (chkdsk /f)
Why it's wrong here
Running chkdsk from the Command Prompt can fix file system errors on the boot drive, but it does not address driver or configuration problems that often cause INACCESSIBLE_BOOT_DEVICE. It is better used after Startup Repair fails.
