Ultimate Boot CD

I have a logonui.exe application error on my notebook, and need help if UBCD will help me how do I do it, I have made the UBCD boot disc but were do I go from there?

I have a Sony VAIO notebook, I went to boot it up the other day and got an error after the XP flash page, the error is logonui.exe does anyone know if UBCD will help fixing this? and if so what do I need to do?

Any help will be much appreciated.
