why when I turn on my laptop, it also need to recover

We need a bit more information then that. What exactly does the message say? Depending on what you mean by recover, it could be anywhere from not being shut down properly to system crashed to other things. But we can't help unless we get the exact message you get when you turn laptop on.
 
Can you take a picture and post here the message you see when you turn your computer on that you are trying to fix?
