bdehdcfg: size

Specifies the size of the system partition when a new system drive is being created. 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.


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


bdehdcfg -target {default|unallocated|<drive_letter> shrink} -size <size_in_mb>


Parameter Description
<size_in_mb> Indicates the number of megabytes (MB) to use for the new partition.


To allocate 500 MB to the default system drive:

bdehdcfg -target default -size 500
