Active

Active specifies whether to mark the partition as active. The basic input/output system (BIOS) or extensible firmware interface (EFI) recognizes active partitions as bootable volumes.

Values

 

true

Marks the partition as active.

false

Does not mark the partition as active.

noteNote
Only one active partition can be set on a hard disk. If an active partition already exists on the disk when this setting is changed to true, the existing active setting is removed and the selected partition is marked as active.

EFI and logical partitions cannot be marked as active. If Active is set for either of these partition types, it is ignored.

XML Example

The following XML output for the DiskConfiguration setting shows two partition modifications. The first modification formats the partition for NTFS, marks the partition as active, and assigns the drive letter C to the partition. The second modification formats the second partition on the disk to NTFS, assigns the drive letter F to the partition, and extends the partition to fill the remainder of the disk.
