Alienware M17X R3

Alright, so, I was beta testing a game, "Star Conflict", and had gone through extensive research and testing trying to determine a confliction within my system towards the game. In the process I ended up formatting and making attempt to re-install Windows 7. I got an error message stating that "Setup was unable to create a new system partition or locate an existing system partition". In the process of that, I switched my Raid 0 setup to ACHI and then rebooted just to find myself ABLE to install windows. Now, I'm in the process of trying to figure out how the heck to get my Raid 0 setup back   it. Does anyone have any advice, I have computer experience, just was NOT ready for Alienware and to be honest, I was NOT aware of AlienRespawn, ugh.
