A technician is using the Command Prompt in the Windows Recovery Environment (WinRE) to repair a legacy BIOS/MBR system that fails to boot after unexpected disk corruption. Place the following boot recovery commands in the correct sequential order to repair the Master Boot Record, partition boot sector, scan for Windows installations, and rebuild the boot configuration data.
- 1Execute bootrec /fixmbr to overwrite corrupted Master Boot Record code on the system partition.
- 2Execute bootrec /fixboot to write a new partition boot sector onto the active system partition.
- 3Execute bootrec /scanos to locate installed Windows operating systems not currently listed in the BCD.
- 4Execute bootrec /rebuildbcd to rebuild the Boot Configuration Data store and add detected Windows installations.
Cevap
The correct sequence begins with repairing the Master Boot Record (bootrec /fixmbr), followed by writing a new boot sector (bootrec /fixboot), scanning for Windows installations (bootrec /scanos), and finally rebuilding the Boot Configuration Data (bootrec /rebuildbcd).
The recovery process must logically proceed from low-level disk structures to higher-level OS configuration stores. First, bootrec /fixmbr fixes the disk's Master Boot Record. Second, bootrec /fixboot repairs the active partition boot sector. Third, bootrec /scanos identifies installed Windows systems. Fourth, bootrec /rebuildbcd reconstructs the Boot Configuration Data database and adds missing Windows entries.
