Vista Intel Matrix Driver

I have 2 Formatted Hard-drives in my Laptop, an Alienware m9750. When trying to install Vista on them with my recovery disk, I cannot create a partition in the unallocated space and get an Error: 0x80042453. If
I try to install there it says that there is a problem and I have to enable the drive's controller in BIOS. I have a feeling it has something to do with my RAID drivers or BIOS, as when I boot, ever since the error that made me reformat them in the first place, the Intel Matrix thing never comes up, and I never get an option to press <CTRL+I>.

With RAID disabled, and vista installed, I can access both hard drives fine.

Anybody know what to do? I was thinking of reinstalling the driver, either the Intel Matrix RAID Controller Driver, or the Chipset driver, but i dont know which, or how to install them
How do I even install drivers without installing vista first?

Trying to install the intel matrix driver in vista prompts an error: your system does not meet the minimum requirements, which is odd, as I downloaded it directly from the alienware site.
Any help would be greatly appreciated.

 

Go into the BIOS and check the controller's mode, is AHCI enabled? If not, enable it.

 

Yes, It is. I think the problem is with the RAID drivers specifically.
I installed Vista one on drive, and tried to install the raid drives, but the Intel Matrix Raid thing wont install. (It says that "My computer does not meet the minimum system requirements")

Flashed the BIOS, updated the chipset, but still nothing. Oh well, I don't really notice the difference in performance anyway.

 

Have you tried installing them via Device Manager?

For example, something like this,
