I posted the question on here a few weeks ago but never got a response. The solution I googled up was a little to much for me so I had to reinstall Ubuntu. I did not know that Vista took three reboots to do the complete update so I got to reinstall Ubuntu three times. I know this is not addressing your question but there is something funky about the Vista security update on a dual boot system. The problem might be the creation of Vista. tab
