How to return Mac OS?

Question

macOS

I don’t understand poppies at all, I got an old laptop, so 2009, I don’t even know what model it is, white with a wide screen and an apple, of course. On it is a buggy ubuntu. The question is - how to return the native poppy axis to it? Ubuntu was installed because The laptop no longer pulled the new poppy axes, so you still need to somehow determine its model and that old poppy axis that it will pull without problems.
MacBook does not react to CMD+R and CMD+Option ⌥+R in any way, loads Ubuntu

Answer 1

Boot with CMD + R pressed, the poppy will connect to the Waffle (or a lanyard if any) and download the recovery image, format the screw - install everything from scratch. Do not forget (if required) to set the correct date and time, in case the battery is no longer dead.

Answer 2

Make a flash drive, there are a lot of instructions, and put it from it.
To choose where to boot from, hold ALT while turning it on.
