Problem with physical build

I have MDT 2010 environment.

Network boot is done via WDS. After the network, it is configured to take the Deployment credentials automatically to proceed with the OS deploy.In my custom settings, SKIPBDDWelcome = Yes is present and also the DS credentials.

I've problem in deploying  the Windows 7 OS on a physical machine.

I am able to deploy the windows 7 OS using the same TS on a VM work station successfully.When I try to deploy on a physical machine, it displays two wizards asking for input from us.

It was configured to work without manual intervention, but  it displays two wizards asking for input from us.

NOTE : If the input is given, deployment happens successfully.
