It happens most of the time when we saw a new operating system whether Windows 8 or Linux Operating System, we try to install along with the current OS and when we are done with the testing we want to remove the newly installed one. But uninstalling or drop the entire partition in which you have installed secondary OS sometimes doesn’t get deleted from the Boot Menu. Eventually it will not harm our System but it seems very annoying every time you have to select the correct OS to boot. And if you are crazy enough like me you ended up with tens of options to choose from in Booting Menu. So here is a very simple trick that will help you remove all the unwanted Operating System entries from the Boot Menu.
