It is clear from all of the above that you do not need windows to run Ubuntu.
If you are happy to run only Ubuntu here is what I would do.
Back up any data/music/pictures you want either on a cd/pen drive/on the cloud
Note any passwords for sites you use and store on a pen drive if possible
Back up your emails and favourites from firefox/chrome etc
Download latest version of Ubuntu from Ubuntu
Test it works on your pc first if it is a newer version!
Select install Ubuntu
Select using Install using entire disk on the Allocate Drive Space page although yours will show windows and may be Ubuntu. Select the use entire disk
Once installed run some updates in your terminal to get it up to date..(you can also follow my reinstall guide I did here to sort other stuff out here I have to reinstall/install ubuntu so have a guide to remember
Stick your backed up data pictures and music back in and start enjoying your Ubuntu and forget about Windows :)
Best Answer
The Windows Installer (WUBI) avoids partitioning the hard drive by creating a virtual partition as a big file inside the Windows partition. It also allows uninstalling Ubuntu in the same way one would uninstall a Windows application.
An WUBI install of Ubuntu depends on components of Windows for (a) installation, (b) during booting to Ubuntu, (c) and for uninstallation.
So if you erase (or uninstall) Windows after installing Ubuntu using WUBI, then Ubuntu will not work.
Solution:
Create a Live USB/DVD and boot from it. Instructions for burning an Ubuntu installation DVD are here: http://www.ubuntu.com/download/help/burn-a-dvd-on-windows.
Choose "Try Ubuntu" first and make sure everything (sounds, graphics, Internet) works.
Click on the Install button if you are satisfied. You will be given a choice to erase Windows.
Warning: This choice will erase all the existing partitions, C: D: etc. and all the data (songs, pictures, etc.). Make backup copies of all the valuable data in an external drive, DVD or some such things before trying to install Ubuntu.
Hope this helps
