My PC was a dual boot PC, i mean i configured it to run two OS by installing two Windows on it which i always select which OS to use on start-up either Windows 7 or Windows 8 but one day i mistakenly set Windows 7 as my default OS which i don’t fancy the boot screen layout, so i changed the default OS to Windows 8 from Windows 7 which i will be showing you here how i did it.

Setting a default OS is helpful if you no longer use your old OS, or if you want to prevent the boot screen options from showing. This article will teach you how to set your default OS to boot automatically under any Windows.

With the help of screenshot, you’ll be able to understand it well…
