What is the error operating system not found?

When I start the computer, the error operating system not found appears.

It doesn't work here anymore, so the window doesn't appear.

What is this error?

This message appears when the window is not found.
Windows files seem to have been deleted for some reason.

Operating system is an operating system such as Windows.
I think it's because the window is broken.
Windows reinstallation is required.

I think I need to reinstall the window.
If your computer is like that, it might be because of something wrong with your hard disk, so check your hard disk.
