wubi - Can I upgrade my ubuntu version and change to be primary OS after originally installing with Wibu?

I have recently installed Ubuntu 12.04 using Wubi 12.04 and I now wish to upgrade to a full installation of Ubuntu 14.04, Before attempting to upgrade through the update center I did some research on upgrading from a Wubi installation (alongside windows) to a full installation making Ubuntu primary and only OS and found that it is in fact doable through the update center however it is just highly recommended to perform a full backup before doing so. I have now finished backing up all the data I need to worry about and began the upgrade process through the update center and received the following error:

Your graphics hardware may not be fully supported in Ubuntu 14.04.

Running the 'unity' desktop environment is not fully supported by your graphics hardware. You will maybe end up in a very slow environment after the upgrade. Our advice is to keep the LTS version for now. For more information see https://wiki.ubuntu.com/X/Bugs/UpdateManagerWarningForUnity3D Do you still want to continue with the upgrade?

My questions are as follows: A. Isnt 14.04 a LTS version??? B, What are your recomendations in order to ensure my graphics driver is installed correctly and im not stuck with bad configs/install?

When it comes to the error it is saying that 14.04, although an lts release, does not have unity2d as you are probably using on your current computer with 12.04, and would have to try and run a full unity3d environment with software acceleration instead of hardware. What are your computer's specs? Also to make it a primary installation you can download boot-repair (google it for instructions on doing so) and elect to install it in the mbr of your drive, then update grub. It will most likely have ubuntu as the default boot option and may even have an option to boot windows below it. If you want to just use ubuntu after that, just delete the windows partition (after backing up everything you want to save) then run sudo update-grub /dev/sd then resize the ubuntu partition(s) CAREFULLY with gparted to take up the full disk.
