Remarks

If the disk signature and partition identifier within the VHD are omitted, it is necessary to search all VHD partitions to locate the partition that contains the boot device element (the application path for a device on which a boot application resides, or the system root for a device on which an operating system resides). This is a referred to as a VPART locate device. To specify a locate device, use the SetVhdDeviceElement method.

A VHD file's parent device is always a BcdDeviceFileData element, which has either a BcdDevicePartitionData or a BcdDeviceLocateStringData element as its parent.
