BOOTDISK_INFORMATION_EX structure
The BOOTDISK_INFORMATION_EX structure contains extended information describing the boot and system disks.
Syntax
typedef struct _BOOTDISK_INFORMATION_EX {
LONGLONG BootPartitionOffset;
LONGLONG SystemPartitionOffset;
ULONG BootDeviceSignature;
ULONG SystemDeviceSignature;
GUID BootDeviceGuid;
GUID SystemDeviceGuid;
BOOLEAN BootDeviceIsGpt;
BOOLEAN SystemDeviceIsGpt;
} BOOTDISK_INFORMATION_EX, *PBOOTDISK_INFORMATION_EX;
Members
- BootPartitionOffset
-
Specifies the offset, in bytes, on the boot disk where the boot partition begins.
- SystemPartitionOffset
-
Specifies the offset, in bytes, on the system disk where the system partition begins.
- BootDeviceSignature
-
If the BootDeviceIsGpt member is FALSE, this specifies the signature for the disk's MBR partition table. Otherwise, this member is unused.
- SystemDeviceSignature
-
If the SystemDeviceIsGpt member is FALSE, this specifies the signature for the disk's MBR partition table. Otherwise, this member is unused.
- BootDeviceGuid
-
If the BootDeviceIsGpt member is TRUE, this specifies the GUID for the boot disk. Otherwise, this member is unused.
- SystemDeviceGuid
-
If the SystemDeviceIsGpt member is TRUE, this specifies the GUID for the boot disk. Otherwise, this member is unused.
- BootDeviceIsGpt
-
TRUE if the boot disk is formatted with the GPT partition table type.
- SystemDeviceIsGpt
-
TRUE if the system disk is formatted with the GPT partition table type.
Remarks
On Windows XP and later, IoGetBootDiskInformation returns this structure to describe the boot and system disks.
