Can you burn a new bootloader a separate Arduino board using an old bootloader

[meowing]

I have accidentally courped my bootloader on my Arduino uno. I was searching for an Arduino nano (because they are small and cheap) on trade me and I found one but it had an old bootloader on it. Is it possible to burn a new bootloader to my Arduino uno using a board that has an old bootloader?

Yes, you can burn a new(er) or old(er) bootloader.

Bootloaders actually don't matter too much as long as they are for the right processor (and the right frequency). If you want to burn a bootloader on the Uno, just take the Uno's bootloader. There have also been plenty people that burned the Uno bootloader in the Nano (after that, program the Nano with board selection Uno).
