Zorluk: KolayTroubleshooting Windows OS Startup and Boot Errors

A technician is servicing a Windows 10 computer that fails to start due to a corrupted boot configuration. After booting from Windows installation media into the Windows Recovery Environment (WinRE) command prompt, which TWO bootrec utility commands should the technician execute to write a new boot sector to the system partition and rebuild the boot configuration store? (Select TWO.)

  1. bootrec /fixbootCevap
  2. bootrec /rebuildbcdCevap
  3. C
    bootrec /cleanmbr
  4. D
    diskpart /repairbcd

Cevap

The correct commands to write a new boot sector and rebuild the BCD store are bootrec /fixboot and bootrec /rebuildbcd.
The command bootrec /fixboot writes a new boot sector to the system partition, and bootrec /rebuildbcd scans connected drives for Windows installations and regenerates the BCD configuration file. Together, these two steps address boot sector corruption and missing BCD settings.

Adım Adım Çözüm

1
Boot into WinRE and open the Command Prompt.
Access to administrative Windows CLI recovery tools.
WinRE provides offline access to system repair utilities when the installed OS cannot boot.
2
Run bootrec /fixboot to repair the boot sector.
A fresh boot sector is written to the system partition.
This resolves startup issues caused by damaged or incompatible boot sector code.
3
Run bootrec /rebuildbcd to scan and rebuild boot entries.
Identified Windows installations are added to the BCD store.
This repairs corrupted BCD files and allows the boot loader to locate the Windows installation.

Anahtar Kavram

Using bootrec switches in WinRE to repair system partition boot sectors and rebuild the BCD database.
