First of all, here is the configuration of my computer:

• Motherboard: Asus H87Plus
• RAM: Corsair Vengeance 32GB
• Processor: Intel i7 4770
• Drive: OCZ RevoDrive 3 x2 (240 GB) (OCZ Revodrive3 is a PCIe module)

I am trying to install the latest version of Ubuntu Desktop (13.10). The problem is that in the UEFI (bios) the drive shows up as a 240 GB drive, but in the Ubuntu installer it shows up as two 120 GB drives. If I install Ubuntu in any of these two drives, it never boots. The screen flickers a few times and comes back to the UEFI menu. I have tried reading up and have come across information that the drive has a "fakeraid", and the solution is to use dmraid. However, when I give the following commands in the terminal (from live CD):

# modprobe dm_mod
# dmraid -ay

it says: no raid disks. And the following command:

# ls -la /dev/mapper/

just shows /dev/mapper/control

How can I install Ubuntu on my computer? what is the correct method?
