Hi DANIYAL,
I understand that you have a specific option that you need which is "Custom recovery - C: drive only" but that option is not on the list, meaning it can't be done. you can only choose from those 2 options provided.
For further assistance regarding your concern, please contact the Sony offices/Sony representative offices nearest to your place of residence in Asia Pacific region http://www.sony-asia.com/countryselector.html?hpid=countryselector:AsiaPacific. Due to proximity, they are in a better position to respond to your questions or concerns.
Regards,
Jen
