I have one pc that has two 120GB hard drives in it. There is currently no operating system installed in my PC. I want to install Ubuntu so it will see and use both hard drives for booting and storage as though they were one. I have looked through the FAQ & blogs and the only one that gets close is the Raid setup, however this version of Ubuntu does not list raid as an option.

I only want Ubuntu on these hard drives, how do I go about doing this?

You need to use an Alternate 12.04.1 ISO for RAID setup - 32bit, 64bit.

For a complete walk-through, please see the Wiki page.

The wiki page you link to says "This page is about Ubuntu 9.10". Is it still relevant for 12.04? –  Jared Beck May 23 '13 at 19:15

use both hard drives for booting and storage as though they were one

To do so, you'll have to check on your computer if the RAID 0 is possible. The easiest way is to give your motherboard information.

FYI : RAID 0 will show only one logical partition as 240Gb but you won't have any backup partition. RAID 1 will show only 120Gb but with redundancy (if one of your HDD burns, your system will still work the time you change the failing HDD)

Probably you are installing the "Ubuntu Desktop" edition, it miss the RAID options. I suggest to install the "Ubuntu Server" edition and follow the Advanced Installation guide. Then you can update the Server edition to the Desktop edition run this:

# apt-get install ubuntu-desktop
