We use FDE with CheckPoint's pre-boot environment and we do not get this screen. I believe this may come from checking the box "Enable lock screen authentication (OneCheck) under "Use native sign on for OS" in the Full DIsk Encryption blade. We have this turned off, so if you have this enabled, try turning this off.
If you would wish to have a custom company image or logo in place of the default CheckPoint or Windows picture you can change this in the Client Settings blade under "Default client user interfaces settings".
