I am trying to install Ubuntu 14.04 from a dvd. I used to have 14.04, but I updated to 14.10, however, I found that 14.10 doesn't play well with my Radeon graphics card.

Steps I have taken

I downloaded the 14.04 ISO from http://www.ubuntu.com/download/desktop

I burned the ISO onto a DVD

When I restart my computer, the installer loads up.

I am able to:

• Select my language and click "Install Ubuntu"
• connect to my WIFI network
• Tell Ubuntu to install additional updates

Problem

When I get to the screen with the partition table, the table is blank.

The field below it that says "Device for boot loader install:" is filled in with /dev/sda and no other options are available.

If I click continue I get an error saying "No root partition is defined" (duh) and If I click one of the +/-/change buttons, the page basically becomes unresponsive, although I can move the mouse.

Here's a picture of my file system setup, at this point I have completely wiped my drive and just have one partition:

I looked at this tutorial and the install process is identical to mine, except mine completely skips step 5. This must be causing the problem

Clicking the "Try Ubuntu" option does work as expected.

I have checked the disk for errors and there were none.

I have done a memory test and no errors were found.

I also performed a secure erase on my hard drive, thinking it might fix the problem. It did not.

I have tried many different partitioning schemes using many different partitioning tools from the live CD. nothing seems to work.

When the application crashes, there is a stack trace, but I cant copy the text. The best I can do is a partial screen shot:
