Local ovf to Hyper V using Virtual Machine Converter with Powershell

Now that I want convert and import a vmware VM to Hyper V. My ovf file with vmdk amd mf files are located in C:OvfHVTest2.

I used the command in powershell:

Import-Module "C:Program FilesMicrosoft Virtual Machine ConverterMvmcCmdlet.psd1"
New-MvmcVirtualMachineFromOvf -DestinationLiteralPath "C:OvfHVTest2"

It gives me the following error message:

New-MvmcVirtualMachineFromOvf : No bootable drive was found for the virtual machine . This could be due to that the virtual machine does not have a valid operating system. At line:1 char:1 + New-MvmcVirtualMachineFromOvf -DestinationLiteralPath "C:OvfHVTest2" + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : WriteError: (Microsoft.Accel...isioningService:HyperVProvisioningService) [New-MvmcVirtu alMachineFromOvf], BootableDriveNotFoundException + FullyQualifiedErrorId : NewMvmcVirtualMachine,Microsoft.Accelerators.Mvmc.Cmdlet.Commands.NewMvmcVirtualMachineF romOvfCommand
