There is no process to start. You can use Dash Core wallet to receive the Dash generated by the miner, but there is no magic button to push instantly start mining.
OK, we are talking in circles here. I have no idea what you mean by mining process. I have already told you need to buy a miner before you can do any mining.
Come find us on Discord and maybe we can chat about it to clarify what you want to do. http://dashchat.org/
