When i boot up my computer it asks me to select the operating system i would like to boot. I have to select the top one as i usually do. The thing is there are three operating systems on the list, i thought i uninstalled them, when i try to load them up, it says they dont exist, but they just stay there, wasting my time every bootup.
How can i get rid of this. Id quite like to completely get them to go away, not make it just choose to boot up from the top one automatically.
