How to create device/osdevice element into BCD file with powershell?

instance of BcdDeviceElement
{
Device = 
instance of BcdDeviceFileData
{
AdditionalOptions = "{9fc76b9c-f8ef-11e3-a7ec-7446a093755c}";
DeviceType = 4;
Parent = 
instance of BcdDevicePartitionData
{
AdditionalOptions = "";
DeviceType = 2;
Path = "\\Device\\HarddiskVolume1";
};
Path = "\\Recovery\\9fc76b9b-f8ef-11e3-a7ec-7446a093755c\\Winre.wim";
};
ObjectId = "{9fc76b9b-f8ef-11e3-a7ec-7446a093755c}";
StoreFilePath = "\\??\\C:\\bcd.bak";
Type = 285212673;
};

I get above information from existed device/osdevice element, but I tried to add the same element into another Windows boot loader element, but I can't.
Would you please help me to fix it? thanks a lots.

I tried to create object with BcdDeviceData, but it not works.
