Contains partition information specific to master boot record (MBR) disks.

Syntax

typedef struct _PARTITION_INFORMATION_MBR {
  BYTE    PartitionType;
  BOOLEAN BootIndicator;
  BOOLEAN RecognizedPartition;
  DWORD   HiddenSectors;
  GUID    PartitionId;
} PARTITION_INFORMATION_MBR, *PPARTITION_INFORMATION_MBR;

Members

PartitionType

The type of partition. For a list of values, see Disk Partition Types.

BootIndicator

If the member is TRUE, the partition is a boot partition. When this structure is used with the IOCTL_DISK_SET_PARTITION_INFO_EX control code, the value of this parameter is ignored.

RecognizedPartition

If this member is TRUE, the partition is of a recognized type. When this structure is used with the IOCTL_DISK_SET_PARTITION_INFO_EX control code, the value of this parameter is ignored.

HiddenSectors

The number of hidden sectors to be allocated when the partition table is created.
