A Windows workstation connected to a corporate domain fails to launch the operating system after an improper system shutdown. Upon power-on, the screen displays the error message 'BOOTMGR is missing'. The computer utilizes a legacy Master Boot Record (MBR) disk partition layout. Which TWO command-line utilities and switches should an IT support technician execute inside the Windows Recovery Environment (WinRE) Command Prompt to write a new system partition boot sector and scan all disks for compatible Windows installations? (Select TWO.)
- bootrec /fixbootAnswer
- bootrec /scanosAnswer
- Csfc /rebuildbcd
- Dbcdedit /fixmbr
Answer
The correct utilities to execute are 'bootrec /fixboot' to write a new boot sector and 'bootrec /scanos' to search all disks for compatible operating system installations.
The command 'bootrec /fixboot' writes a new boot sector to the system partition, resolving issues where BOOTMGR is corrupted or missing. The command 'bootrec /scanos' scans all disks for Windows installations compatible with the current OS and displays any entries missing from the Boot Configuration Data store.
