First, you need to boot into the live media, and where you are confronted with the options to boot (default, compatibility, memory test etc.), select default and press tab to edit the options.
Once here, add the word "nomodeset" after the "--" (include a space so it's: -- nomodeset).
This should boot the OS, then drop you into a command line.
From here type:
>apt-get remove xserver-xorg-video-radeon
This should now get you into a fully fledged graphical environment, where you can install your OS.
After it's installed, you'll be right back to square one with a black screen.
So, as soon as you turn on your PC, hold shift, and you'll be brought to the GRUB menu. Select recovery here, and once again you'll find yourself dropped into the command line.
Log in as normal
>sudo nano /etc/apt/sources.list
find the last two sources that are hashed out, and unhash them.
>Ctrl + X then Ctrl + Y (save and exit)
>sudo apt-get update
>sudo apt-get install fglrx
