EasyBCD is a computer program that helps your computer start up correctly. When you turn on your computer, there are different things that need to happen in order for your computer to start up, kind of like putting on your shoes, then your shirt, then your pants. EasyBCD helps organize these "steps" so that your computer knows what to do and in what order. It's like a little helper that makes sure everything is in the right place and working properly, so that your computer can start up without any problems.
