Alienware M18xR2: Resetting to manufacturer settings without backup-partition

  Hello everyone reading this post, I have recently changed the hard-drive in my Alienware because the one that came with my computer and had the back-up partition to reset to manufacturer settings got corrupted and stopepd working. I was not able to make a copy of the partition before I switched out the hard drives so now I dont have microsoft office, alien autopsy, and all that stuff because I was only able to load the OS. I have both dvd's i received with the computer (Resource dvd and the Microsoft windows 7 dvd) and from what I can tell the microsoft windows 7 dvd only re-installs the os not a full reset to manufacturer settngs and also i have heard to never ever use the resource dvd because it messes everything up....... so exactly what is the purpose of the resource dvd and is there any way I can get my computer back to manufacturer settings? i have heard I can pay Dell 130 bucks for them to send me a dvd I can use to do so but would that happen to be one of the dvd's that already came with the computer?
