BootPrep Commands

  • Artigo

To use the BootPrep commands, type the following syntax in a command prompt.

BootPrep [/dDrive] [/mMBRBackupFileName] 
[/bBackupFileName] [/y] [/r] [/iExternalDataFile]

Parameters

  • /dDrive
    Uppercase drive letter without the colon (:), for example, /dC. The default is the C drive.
  • /mMBRBackupFileName
    Name of file for MBR sector backup, for example, /mmbr.old. If /m is specified with no file name, no backup is created, which is the default behavior.
  • /bBackupFileName
    Name of file for PARTITION BOOT sector backup, for example, /bbootrec.old. If /b is specified with no file name, no backup is created. The default file is Bootrec.old.
  • /iExternalDataFile
    Name of file containing data for the new PARTITION BOOT sector. The default is to use internal data.
  • /r
    Read-only mode. Save output for MBR and BOOT sectors to their backup file locations.
  • /y
    Answers "Yes" to all questions. Use this parameter with caution.

Example

The following code sample shows a typical syntax.

A:\>BootPrep

This example copies the PARTITION BOOT sector of the C drive to A:\Bootrec.old, and then replaces it with a new PARTITION BOOT sector using internal data. The new boot sector is in read/write mode.
