One of the primary reasons I purchased HDM Pro 14 was to use the P2V feature. However, I'm having some trouble figuring out how to get it to work. I am running Windows 8.1 64-bit. I have used the P2V feature to create a .vdi file of my OS for using with VirtualBox. I have downloaded the most recent version of VirtualBox version 4.3.6. When I try to boot the .vdi file in VirtualBox, it says, "FATAL: Could not read from the boot medium! System halted." I have tried to research this issue on the web. It seems that a common response is that I need to attach a bootable .iso file to the virtual machine. So, I attached a copy of my Win 8.1 installation .iso file. However, now VirtualBox simply installs an instance of Win 8.1 in the virtual machine. How do I boot the .vdi file created by Paragon in VirtualBox? Thanks for any advice or pointers. I'm really wanting to be able to use this P2V feature in HDM.
