Zorluk: OrtaTroubleshooting Windows OS Startup and Boot Errors

A Windows workstation fails to boot after a failed third-party hardware driver update, repeatedly freezing during the initial Windows boot splash screen. A technician accesses the Windows Recovery Environment (WinRE) Command Prompt to diagnose and resolve the boot failure offline. Which TWO command-line actions or utilities should the technician use to resolve the corrupted driver issue and allow the operating system to start successfully? (Select TWO.)

  1. Execute sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows to verify and repair system files in the offline installation.Cevap
  2. Use bcdedit /set {default} safeboot minimal to force the system to launch in Safe Mode on the next startup.Cevap
  3. C
    Execute bootrec /fixmbr to rewrite the Master Boot Record and restore disk signature tables.
  4. D
    Run chkdsk C: /f /r to format the system partition and rebuild the file allocation structure.

Cevap

The correct troubleshooting actions are executing the System File Checker command with offline directory parameters to replace corrupted files and configuring BCDedit to force the workstation into Safe Mode to isolate and remove the faulty driver.
When Windows fails during the driver loading phase, running System File Checker with offline flags (/offbootdir and /offwindir) allows WinRE to replace damaged binaries. Concurrently, setting the safeboot minimal flag via BCDedit forces Windows into Safe Mode on the next reboot, which bypasses non-essential third-party drivers and allows the technician to log in and uninstall the offending update.

Adım Adım Çözüm

1
Identify the cause of the boot failure.
The failure occurs during driver initialization after a driver update, pointing to corrupt system files or a third-party driver conflict.
Isolating whether the boot failure is caused by boot loader corruption versus driver/system file corruption dictates the appropriate repair commands.
2
Run System File Checker targeted at the offline target Windows installation directory.
The utility scans integrity of system files on C:\Windows and replaces corrupted system binaries without booting into full Windows.
Standard sfc /scannow requires offline flags (/offbootdir and /offwindir) when executed from WinRE command prompt.
3
Configure the system to boot into Safe Mode using BCDedit.
The default boot loader configuration is updated with the safeboot minimal flag.
Safe Mode loads only core system drivers, bypassing the corrupted third-party driver and granting access to Device Manager for driver rollback.
