[Solved] Lenovo Legion Laptop Won't Start: Checking Media, Boot Manager Issue & Windows 10 Access

I have a serious problem, the laptop switches to the image below when it starts: Boot Manager




Whatever I choose, the message checking media_ appears later. The laptop is practically new, still under warranty.

I tried to enter the bios when starting, but I failed. Do I have to return my laptop? Maybe there is a chance to fix it? I have to do a project. Here's something.

The laptop is Lenovo Legion and Windows 10
I will be grateful for help.

At some point, another option appeared with the words Windows etc, after accepting enter, the laptop restarted.
