Just after you BIOS finishes displaying its stuff, press shift a few times to make the GRUB menu appear. Choose Ubuntu advanced options and choose to boot in safe graphics mode.
You should be able to do the install. After the install if you still have problems (like I did) the do this.
Boot in safe graphics mode again, but this time from the HDD and not the Disk, and log in. If this doesn't work you can try hit ctl-alt-F1 and log in via the command prompt.
Once in the safe graphics mode open up a terminal by pressing ctl-alt-T [not necassary if you did the ctl-alt-F1 step]
Type these command in one by one.
sudo apt-get --purge remove xserver-xorg-video-nouveau
sudo apt-get install linux-headers-`uname -r`
sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current
sudo update-alternatives --config gl_conf
sudo update-initramfs -u
Reboot. This worked for me.
