I have a ~1.9TB RAID 0 set up comprised of 3 640 GB HDs. I created a ~1.5 TB partition for Windows 7, which is running flawlessly, and was going to split the remaining space half and half with an Ubuntu and ArchLinux installation. Right now I'm trying to install Ubuntu and am having a very hard time doing so.
I created a bootable Ubuntu flash drive. The iso did match hashes with the expected hash value.
If I boot from the flash drive I get to the window that asks me if I want to try Ubuntu or install. Upon pressing install I then navigate to the "Installation type" window which shows absolutely no devices. At the bottom there's /dev/sda selected for "device for boot loader installation:" and if I press on the drop down that device is the only thing shown. If I press "Install now" I get an error and it then goes to a black screen.
Upon reboot I then press "Try now" and am able to get in the Ubuntu desktop. I downloaded gparted with the kparted add-on and when I open it it shows only my 3 HDs and the flashdrive, but no RAID. It says all 3 HDs have their full capacitance unallocated and doesn't detect any partitions. If I open Disks it shows one hard drive as having a partition but the other 3 are completely blank.
I then open Terminal and type the follow, which gives me the following:
$ sudo dmraid -tay
>isw_djejjcdice_The Future: 0 3750769920 striped 3 256 /dev/sda 0 /dev/sdc 0
$ sudo dmraid -ay
>RAID set "isw_djejjcdice_The Future" active
>ERROR: opening "/dev/mapper/isw_djejjcdice_The Future"
I then open gparted which gives me this error: "Could not stat device /dev/mapper/isw_djejjcdice_The Future - No such file or directory."
I then open Disks and it shows the RAID as "1.9 TB Block Device /dev/dm-0". It shows I have a 1.6 TB NTFS partition and 315 GB of free space.
I then hit Install Ubuntu 12.10, get to the "Installation type" screen and it shows 4 RAID set ups:
-/dev/mapper/isw_djejjcdice_The type=ntfs size=104 MB used=unknown
-/dev/mapper/isw_djejjcdice_The type=ntfs size=1605713 MB used=unknown
-free space size=314574 MB
-/dev/mapper/isw_djejjcdice_The\x20Future1 type=ntfs size=104 MB used=unknown
-/dev/mapper/isw_djejjcdice_The\x20Future2 type=ntfs size=104 MB used=unknown
-/dev/mapper/isw_djejjcdice_The\x20Future2 type=ntfs size=1605713 MB used=unknown
I then choose the Device for boot loader installation:
/dev/mapper/isw_djejjcdice_The\x20Future3 Linux device-mapper (linear) (314.6 GB)
and press "Install Now"
Which gives me this:
Sorry, Ubuntu 12.10 has experience an internal error.
If you notice further problems, try restarting the computer.

(I'm stopping it there because I don't want to type any more of it, if there's a part you want of it just let me know.)
What can I do?
Thank you very much.
