Hi I found a nice tool to convert fromatVMDK format to VHD format this is required now a days as VHD format allows to add a virtual hard disk as new partition and dual boot option.
So, if you wants to fully utilize your hardware capabilities its better to use VHD with a new partition and making it dual boot option.
