BOOTDISK_INFORMATION structure

The BOOTDISK_INFORMATION structure contains basic information describing the boot and system disks.

Syntax


typedef struct _BOOTDISK_INFORMATION {
  LONGLONG BootPartitionOffset;
  LONGLONG SystemPartitionOffset;
  ULONG    BootDeviceSignature;
  ULONG    SystemDeviceSignature;
} BOOTDISK_INFORMATION, *PBOOTDISK_INFORMATION;

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 boot disk is formatted with an MBR partition table, this specifies the signature for the disk's MBR partition table. Otherwise, this member is unused.

SystemDeviceSignature

If the system disk is formatted with an MBR partition table, this specifies the signature for the disk's MBR partition table. Otherwise, this member is unused.

Remarks

IoGetBootDiskInformation returns this structure to describe the boot and system disks.

Requirements

Version

Drivers on Microsoft Windows XP and later versions of the Windows operating system should use the BOOTDISK_INFORMATION_EX structure instead.
