Direct3D 11 - The specified device interface or feature level is not supported on this system

I am new to Direct3D and trying to execute this piece of code:

...I get an error saying I have no suitable driver for this program

Interestingly, I could execute this code successfully when I was testing it without any vertex buffers and triangles*. But suddenly adding them caused a driver error... I tried to find an answer here but one guy had a problem with a specific driver type and I can't even run the program with any of them. I also watched a youtube tutorial which recommends to install program that can work with message coming from the application (it was about final products like games and I have a debug program). Thank you

*- it seems that it doesn't matter if I have geometry initialized or not

P.S. Changed code to match the "minimal, reproducible example" rule, so now you can try it yourself (if you have Windows SDK)

I've finally found out the problem here: I had this code in main.cpp file:

Window* mw = new Window(800, 600, "Name"); // Window init
Scene* sc = new Scene(mw->g_hWnd, 75); // DirectX init
if (!mw->Show() || !sc->Check())
{
    delete mw;
    delete sc;
    return -1;
}

And it appears that Window constructor doesn't initialize the window itself but the mw->Show() which has InitInstance() call in it. That's why I edited my code like:

Window* mw = new Window(800, 600, "Name"); // Window init
if (!mw->Show())
{
    delete mw;
    return -1;
}
Scene* sc = new Scene(mw->g_hWnd, 75); // DirectX init
if (!sc->Check())
{
    delete mw;
    delete sc;
    return -1;
}

If you're still encountering this error, check this website. It seems someone has rewritten my question in more sophisticated English and answered it :)
