How can I change the operating system on my MacBook Pro A1286?

I've tried everything and I get a blue screen with Windows, and with Linux they don't even load.

First thing; I'm pretty certain you have to have a working compatible version of macOS installed, then you can create a partition for windows or linux. Do you have that?

Or at least boot from Recovery or external media.
