Failure while accessing Bcd using wmic

I am getting an error when I try to access the EnumerateObjects method
of the BcdStore class using wmic.

I initially ran the GetSystemDisk method to see that I can access the
BcdStore (see below). This worked fine.
________________________ cmd window output begins
_________________________________
C:\>wmic /namespace:\\root\wmi class BcdStore call GetSystemDisk
Executing (BcdStore)->GetSystemDisk()
Method execution successful.
Out Parameters:
instance of __PARAMETERS
{
Disk = "\\Device\\Harddisk0\\DR0";
ReturnValue = TRUE;
};
________________________ cmd window output ends

Then I ran the EnumerateObjects method, but got a failure, please see
below. The different versions are just different variations of how to
pass the arguments to the method, But this didn't work.

Any help would be appreciated.
