I’ve been trying to find a linux programming similar to Rufus to flash images of OSes on a thumb drive.
Nothing from the listicles on the internet or the programs in flatpak have worked for me as well as Rufus on Windows.
What have you used that’s worked well? Or, could I run Rufus on my linux machine with WINE?
Ventoy is great as others have said, and probably would do what you want since it has its own installer and is its own bootloader, and can boot isos loaded on the USB drive.
If you want something that works, in my experience, as well as Rufus, maybe take a look at Balena Etcher, too.
