Hey guys, since i got my new mobo the other week and re installed windows 7 etc its all been fine. But when i load up the system at first it asks me what operating system i would like to load (heard this is called a dual boot) and both options are windows seven. If i clicked the first one it loads normally and the second one just takes me to a black screen. Any idea how to remove that second option so it just skips that annoying screen and loads my computer without me having to select the first windows 7 option.
