Properties
The BcdDeviceQualifiedPartitionData class has these properties.
-
DiskSignature
-
-
Data type: string
-
Access type: Read-only
If the PartitionStyle property is a GUID partition table (GPT), the DiskSignature property is the disk signature as a GUID in string format (for example, "{7c69a706-eda5-11dd-bc09-001e4ce28b8f}"). If the PartitionStyle property is a master boot record (MBR), the DiskSignature property is the decimal MBR disk signature in string format (for example, "402653184" for 0x18000000).
-
-
PartitionIdentifier
-
-
Data type: string
-
Access type: Read-only
If the PartitionStyle property is GPT, the PartitionIdentifier property is the partition signature as a GUID in string format (for example, "{6efb52bf-1766-41db-a6b3-0ee5eff72bd7}" ). If the PartitionStyle property is MBR, the PartitionIdentifier property is the decimal MBR partition offset in string format (for example, "82837504" for 0x4F00000).
-
-
PartitionStyle
-
-
Data type: uint32
-
Access type: Read-only
The partition style. This property can be one of the following values.
Value Meaning - GPT
- 1
The partition is described in a GPT. - MBR
- 0
The partition is described in an MBR. -
Remarks
The BcdDeviceQualifiedPartitionData class uniquely identifies a boot partition by its partition style, disk signature, and partition identifier. An application can enumerate a qualified partition by using the GetElementWithFlags method of the BcdObject class with Flags parameter set to Qualified (1).
To set a qualified partition device, use the SetQualifiedPartitionDeviceElement method of the BcdObject class and specify a partition style, disk signature, and partition identifier.
