So for a while now I've been trying to dual boot windows and Ubuntu on my dell XPS 8300, but I always have trouble when it comes to partitioning.
I burned the 12.04 64-bit iso to an empty CD and booted off of it. I then clicked "Try Ubuntu" and connected to wifi. Next I opened up the install wizard completed everything perfectly until I got to this screen (http://i.imgur.com/UkIb3.jpg). Based off of many install guides and tutorials I have read I was expecting a "Install Alongside Windows" option but none was available. I then proceeded to select "Something else" to look at my partitions (http://i.imgur.com/zub4C.jpg).
Here is the part I'm confused with and I want to make sure I'm doing everything right so nothing gets messed up.
The installer shows me that I have one 1TB drive divided into three partitions. In reality, I have two 500GB drives. Gparted says the same as the installer (http://i.imgur.com/S6jcx.jpg). After doing a little research, I found that I have some sort of software called "RAID" that is doing this.
So finally my question to you is: "How can I safely dual boot Windows and Ubuntu with this setup?" Keep in mind that In reality I have two 500GB drives being connected with RAID.
Below is some more information on my system that I got from Speccy and Windows Disk Management Tool. Thanks for your time and support.
