Bdehdcfg: size

Updated: April 17, 2012

Applies To: Windows 7, Windows Server 2008 R2

Specifies the size of the system partition when a new system drive is being created. For an example of how this command can be used, see Examples.

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

 

Parameter Description

<SizeinMB>

Indicates the number of megabytes (MB) to use for the new partition.

If you do not specify a size, the tool will use the default value of 300 MB. The minimum size of the system drive is 100 MB. If you will store system recovery or other system tools on the system partition, you should increase the size accordingly.

noteNote
The size command cannot be combined with the target <DriveLetter> merge command.

The following example illustrates using the size command to allocate 500 MB to the default system drive.

bdehdcfg -target default -size 500
