     that is included in the disk if creating a VM from user-image or a
     specialized VHD. <br><br> Possible values are: <br><br> **Windows**

     disk will be copied before being attached to the virtual machine. If
     SourceImage is provided, the destination virtual hard drive must not
     exist.

     value is used when you are using a specialized disk to create the virtual
     machine.<br><br> **FromImage** \\u2013 This value is used when you are
