Formatting Alienware M17X R4

So me being an idiot I accidentally removed the Partition with all the Alienware stuff in it to allow me to use AlienRespawn. How would i go about formatting my laptop now that I don't have that. 

I've tried on multiple occasions to use the disc that came with the laptop itself along side the drivers needed to do the format but that was saying that i had the wrong drivers.

Thanks, Daniel.
