What recovery console command writes a new master boot record on the hard drive?

The command that writes a new master boot record (MBR) on the hard drive is "fixmbr." This command is part of the Recovery Console in Windows operating systems and is used to repair the MBR when there are issues that prevent the operating system from booting properly.

The MBR is a special type of boot sector that contains information on how the logical partitions, containing file systems, are organized on the disk. When you use the fixmbr command, it writes a new MBR to the disk without changing the existing partitions or their data. This can resolve issues caused by corrupt or missing MBR, enabling the computer to boot correctly again.

Understanding the function of this command is crucial for tasks related to system recovery and repair, especially when dealing with boot-related problems. Other commands mentioned, while related to recovery processes, serve different purposes. For example, "Bootrec" is used for various boot repair tasks, but it is not specifically designated for writing a new MBR in the same way.
