Updated: April 17, 2012

Applies To: Windows 7, Windows Server 2008 R2

Prepares a partition for use as a system drive by BitLocker and Windows Recovery. By default, this partition is created without a drive letter. For examples of how this command can be used, see Examples.

bdehdcfg -target {default|unallocated|<DriveLetter> shrink|<DriveLetter> merge}

 

Parameter Description

default

Indicates that the command-line tool will follow the same process as the BitLocker setup wizard.

unallocated

Creates the system partition out of the unallocated space available on the disk.

<DriveLetter> shrink

Reduces the drive specified by the amount necessary to create an active system partition. To use this command, the drive specified must have at least 5 percent free space.

<DriveLetter> merge

Uses the drive specified as the active system partition. The operating system drive cannot be a target for merge.

The following example depicts using the target command to designate an existing drive (P) as the system drive.

bdehdcfg -target P: merge
