RAID setup in BIOS - Alienware 14

Hello,

I've butchered the RAID setup of my Alienware14 and need some help on what to do next. Currently, the system can not boot because there is no boot media as I've messed up my hard drives (I deleted the RAID configuration) in an attempt to do a fresh factory install. Here's the run down and where I'm at.

1. I'm in the Boot Manager (F12) menu and hit "Intel(R) Raid Storage Technology"

2. There is an option to "Create RAID Volume" and below that, it lists my 2 hard drives which are Non-Raid Physical Disks, Port 0: WDC 750GB, and Port 5, INTEL mSATA 80GB

When hit create RAID Volume, having to select both HDD and SSD, it only allows me to create a volume size of 152,633MB. When this is created, I dont have the option to create any other volumes and I'm left with 1 drive thats only 153GB.

Originally, I had 3 drives, there was a 10.5GB drive (assuming this was from the SSD), a 65GB Caching drive (from SSD as well) and also a 686GB HDD. Can anyone help in how I can get the 686GB HHD back and use the entire 80GB SSD as a caching drive?

Thanks - Nebu
