Hello i need help to switch one operating system to another one just by clicking the switch button . I saw that in a video long time ago where we can have a button to click to go one system to another . Can anyone guide me how i can get the button or where i can install it .
Right now i am using two operating system on my computer but if i want to change i need to restart my computer and select other one. However ,i want to get something where i don't need to restart my computer but rather by a click i switch the system .
