If you have a dual-boot system with Linux and Windows, then you probably know that when you start your system first Linux boot loader appears showing Linux as well as Windows boot entries and if you select Windows from the list, it starts Windows.
Suppose a situation when you want to remove Linux from your system and want to use only Windows, then how will you do it?
Many times people delete the partitions having Linux installed from "Disk Manager" but it doesn't remove Linux completely. The Linux boot loader still appears at startup but since you deleted Linux partitions, the boot loader gets corrupted and your system becomes unusable.
So if you are also facing this problem or you faced this problem in past and could not get a working solution, then read this tutorial and you can follow it if you find yourself in a similar situation.
