I have a Dell Inspiron 14R that came with Ubuntu 11.1 installed from the Factory. I had multiple troubles and I had to re-install, for which I used an 12.04 ISO that I downloaded from Ubuntu site.
Now, the System boots but some stuff -like Touchpad or GPU acceleration- is not working so I want to restore the Factory version. Is that possible? Some forums direct to a Recovery partition, but I don't have one (I only see a Dell Utility one)
