I need the boot screen to select the usb auto-installer, I have installed BigSur, when I restart I press the key to change boot and it stays black, the monitor does not start and I do not see anything.

You can do that by blessing the Bootloader so that it starts automatically.

How do you do that? in the installation when it restarts automatically I will not be able to have problems?, if it starts automatically will it recognize the graphic?

Of course, if OC is configured correctly.

Por supuesto, si OC está configurado correctamente.

Pero, ¿cómo hago eso? He visto en un tutorial que primero seleccionas un ícono que dice EFI y luego eliges el instalador USB, ¿cómo haces que todo esto se haga automáticamente?

También he leído que se puede flashear la tarjeta gráfica, ¿cómo se hace? porque todos los videos que he visto están en Windows y solo tengo una Mac. Gracias por su paciencia.

But how do I do that? I've seen in a tutorial that you first select an icon that says EFI and then choose the USB installer, how do you get this all done automatically?

I have also read that you can flash the graphics card, how is it done? because all the videos I've seen are on windows and I only have a Mac. Thanks for your patience.

Sorry but google translated it without realizing it.

I have done the same using NVIDIA GT710, GTX750, RX550, RX580, without flashing the GPU.

It is a complex process.
