Thank you can you tell me how do it please and will he lose everything on it

It normally takes a couple of minutes if it's starting from cold boot. But if it's taking a long time, try doing a

Power Cycle. This usually fixes most common issues.

But if that doesn't work, you might want to do a
factory reset instead.

I would get the warranty/service process started if the system is not booting up at all. Since you recently bought it, it shouldn't be an issue but contact them for sure.

Great. Thanks for your help
