Comprehensive List of RMBR Commands with Descriptions

**RMBR** (Remove MBR) is a command-line utility used to remove or manipulate the Master Boot Record (MBR) on a disk. This can be useful for cleaning up disks before reformatting or preparing them for new installations. Below is a detailed list of RMBR commands, along with descriptions and examples.

---

1. Removing the Master Boot Record
Description: Removes the MBR from a specified disk, effectively wiping out the partition table and bootloader.

Code:

rmbr.exe [Disk]

Example: To remove the MBR from disk 0:

Code:

rmbr.exe \\.\PhysicalDrive0

Warning: This operation will remove the partition table, making the disk's contents inaccessible until reformatted.

2. Creating a Backup of the MBR
Description: Creates a backup of the current MBR before removing it, allowing you to restore it later if needed.

Code:

rmbr.exe -b [BackupFile] [Disk]

Example: To back up the MBR of disk 0 to `mbr_backup.bin`:

Code:

rmbr.exe -b mbr_backup.bin \\.\PhysicalDrive0

3. Restoring the MBR from a Backup
Description: Restores a previously backed-up MBR to a specified disk.

Code:

rmbr.exe -r [BackupFile] [Disk]

Example: To restore the MBR on disk 0 from `mbr_backup.bin`:

Code:

rmbr.exe -r mbr_backup.bin \\.\PhysicalDrive0

4. Displaying the MBR Information
Description: Displays information about the MBR on a specified disk, including partition table details.

Code:

rmbr.exe -i [Disk]

Example: To display the MBR information for disk 0:

Code:

rmbr.exe -i \\.\PhysicalDrive0

5. Clearing the Partition Table Only
Description: Clears the partition table without removing the entire MBR, which can be useful for preparing a disk for a new partitioning scheme.

Code:

rmbr.exe -c [Disk]

Example: To clear the partition table on disk 0:

Code:

rmbr.exe -c \\.\PhysicalDrive0

6. Restoring a Standard MBR
Description: Writes a standard MBR to the disk, typically restoring the original boot code but not the partition table.

Code:

rmbr.exe -s [Disk]

Example: To restore a standard MBR to disk 0:

Code:

rmbr.exe -s \\.\PhysicalDrive0

7. Verifying the MBR Integrity
Description: Compares the current MBR on a disk with a backup to verify its integrity.

Code:

rmbr.exe -v [BackupFile] [Disk]

Example: To verify the MBR on disk 0 against `mbr_backup.bin`:

Code:

rmbr.exe -v mbr_backup.bin \\.\PhysicalDrive0

8. Writing a Custom MBR
Description: Writes a custom MBR from a binary file to a specified disk, which can be used for specialized boot configurations.

Code:

rmbr.exe -w [CustomMBRFile] [Disk]

Example: To write a custom MBR from `custom_mbr.bin` to disk 0:

Code:

rmbr.exe -w custom_mbr.bin \\.\PhysicalDrive0

9. Force Removing the MBR
Description: Forcefully removes the MBR, bypassing any warnings or checks.

Code:

rmbr.exe -f [Disk]

Example: To forcefully remove the MBR from disk 0:

Code:

rmbr.exe -f \\.\PhysicalDrive0

Warning: Use this option with caution as it will immediately remove the MBR without prompting.

10. Displaying Help Information
Description: Displays help information for the RMBR command, listing all available options and their descriptions.

Code:

rmbr.exe -h

Example: To display help information for RMBR:

Code:

rmbr.exe -h

Conclusion

The **RMBR** command is a powerful utility for managing and removing the Master Boot Record on a disk, making it an essential tool for system administrators and advanced users. By mastering these commands, you can effectively prepare disks for reformatting, clean up unwanted boot records, and ensure the integrity of your disk setups.

Happy Disk Management!
