Comprehensive List of MBR Commands with Descriptions
**MBR** (Master Boot Record) is a command-line utility used for managing and manipulating the Master Boot Record on a disk. Below is a detailed list of MBR commands, along with descriptions and examples.
1. Backing Up the Master Boot Record
Description: Creates a backup of the MBR from a specified disk and saves it to a file.
Example: To back up the MBR of disk 0 to `mbr_backup.bin`:
2. Restoring the Master Boot Record
Description: Restores the MBR from a backup file to a specified disk.
Example: To restore the MBR to disk 0 from `mbr_backup.bin`:
3. Displaying the Master Boot Record
Description: Displays the contents of the MBR on a specified disk in hexadecimal format.
Example: To display the MBR of disk 0:
4. Clearing the Master Boot Record
Description: Clears (zeros out) the MBR on a specified disk, effectively removing the partition table and boot code.
Example: To clear the MBR on disk 0:
Warning: This operation will destroy all partition information on the disk.
5. Writing a Custom MBR
Description: Writes a custom MBR from a binary file to a specified disk.
Example: To write a custom MBR from `custom_mbr.bin` to disk 0:
6. Verifying the Integrity of the MBR
Description: Compares the MBR on a specified disk with a backup file to verify its integrity.
Example: To verify the MBR on disk 0 against `mbr_backup.bin`:
7. Displaying the Partition Table
Description: Displays the partition table entries within the MBR of a specified disk.
Example: To display the partition table on disk 0:
8. Editing the Partition Table
Description: Manually edits the partition table entries in the MBR of a specified disk.
Example: To edit the partition table on disk 0:
Note: Use this command with caution, as incorrect edits can make the disk unbootable.
9. Restoring the MBR from a Standard MBR File
Description: Restores the MBR using a standard MBR binary file provided by the utility or the operating system.
Example: To restore the standard MBR to disk 0:
10. Logging Operations to a File
Description: Logs the details of MBR operations to a specified file for auditing or troubleshooting purposes.
Example: To log the MBR backup operation to `mbr_log.txt`:
11. Displaying Help Information
Description: Displays help information for the MBR command, listing all available options and their descriptions.
Example: To display help information for the MBR utility:
Conclusion
The **MBR** utility is a powerful tool for managing and manipulating the Master Boot Record on a disk. By mastering these commands, you can efficiently back up, restore, and edit the MBR, ensuring the integrity and bootability of your systems.
Happy Managing!
