A user states their workstation will not reach the login screen. Which of the following commands can be used to write a new partition boot sector to the system partition in the Recovery Console?
The correct answer is C. FIXBOOT. The FIXBOOT command in the Windows Recovery Console rewrites the boot sector of the active system partition, which is needed when the partition boot sector is corrupt and prevents reaching the login screen.

Why each option
The FIXBOOT command in the Windows Recovery Console rewrites the boot sector of the active system partition, which is needed when the partition boot sector is corrupt and prevents reaching the login screen.
FIXMBR repairs the Master Boot Record on the physical drive, which is a different structure from the partition boot sector.
BOOTCFG is used to rebuild or modify the boot.ini configuration file, not to repair the boot sector itself.
FIXBOOT writes a new Windows-compatible boot sector to the system partition, replacing a damaged or missing one. This targets the partition-level boot code (distinct from the MBR), and is the appropriate command when the OS fails to start because the partition boot sector cannot hand off execution to the OS loader.
DISKPART is a disk partitioning and volume management utility and cannot write a new boot sector.
