After a system crash, a user restarts a Windows 10 desktop and receives a black screen with the error message 'Invalid partition table'. A technician boots the workstation into the Windows Recovery Environment (WinRE) command prompt to repair the Master Boot Record (MBR) and restore the boot configuration settings. Which TWO commands should the technician execute to resolve this specific boot issue? (Select TWO)
- bootrec /fixmbrCevap
- bootrec /rebuildbcdCevap
- Cchkdsk /f /r
- Dsfc /scannow
Cevap
The technician should run bootrec /fixmbr to repair the corrupted Master Boot Record structure and bootrec /rebuildbcd to scan for Windows installations and rebuild the Boot Configuration Data store.
The 'Invalid partition table' error occurs when the Master Boot Record boot code or partition table references are corrupted. Running 'bootrec /fixmbr' writes a valid Windows-compatible MBR to the system partition without altering existing partition structures. Following up with 'bootrec /rebuildbcd' ensures that any missing or unreferenced Windows OS installations are identified and incorporated into the Boot Configuration Data repository, allowing proper boot continuation.
