I know that there are many well-known methods for creating a bootable USB stick, but all these alternatives needs to format the USB stick.

What I'm looking for is some alternative method to create an USB bootable stick without the need of formatting it.

That's because I usually have an USB stick that I use to transport files and everything, and I don't like having to backup these files every time I have to load a new ISO to the USB stick.

    Just because a question mentioned "software" doesn't make it a product recommendation question. I've edited the question to remove any mention of software to make it clear that this is a "how can I do this" question. I found the recommendation below a valuable resource, and would love to have seen more alternative methods if there are any.
