A field technician is troubleshooting a Windows workstation configured with a legacy MBR partition scheme that fails to boot, displaying the error message 'Invalid partition table' on a black screen. Upon booting into the Windows Recovery Environment (WinRE) Command Prompt, which TWO of the following troubleshooting actions should the technician perform to repair the boot structure and make the primary drive bootable? (Select TWO.)
- Run bootrec /fixmbr to repair the corrupted Master Boot Record code on the system partition.Cevap
- Use diskpart to select the primary system partition and mark it as active.Cevap
- CRun bootrec /rebuildbcd to recreate the EFI System Partition bootloader configuration.
- DExecute sfc /scannow to replace corrupted Windows kernel binaries from the recovery image.
Cevap
The technician must execute `bootrec /fixmbr` to repair the Master Boot Record code and use `diskpart` to set the primary partition as active.
An 'Invalid partition table' error on a legacy MBR system signifies either corruption in the Master Boot Record or that no drive partition is designated as active. Running `bootrec /fixmbr` writes a compatible MBR to the system partition to correct MBR boot code corruption. Using `diskpart` to set the Windows system partition to 'active' allows the BIOS to hand off boot control to the partition containing boot files.
