Ventoy makes reinstalling operating systems or testing Linux distros much easier.
Install Ventoy once, then simply copy ISO files to your USB drive, no need to reformat it every time you add another image. It also supports multiple operating systems, Secure Boot, persistence, and many rescue tools.

It does mean you have to repackage isos if you want to include/update files.
For example, it made an automated.xml file for windows install a lot more complicated. But now I have a very nicely scripted iso builder for customised windows installations (I work in the events industry, so things like digital signage and show machines can be 95% configured before I even have to interact with it).
It's still windows, but it's now hands free from iso boot to being able to use it with the software and settings I want.
