style: A value from the VDS_PARITION_STYLE enumeration that describes the disk partition format.

MbrPartInfo: Contains information for an MBR partition.

partitionType: The byte value indicating the partition type to change the partition to.

GptPartInfo: Contains information for the partition of a GPT.

partitionType: The GUID indicating the partition type to change the partition to.<48>
