The Ventoy developer notes that this has been tested for Fedora / Arch Linux using archlinux-2021.03.01-x86_64.iso and Fedora-Workstation-Live-x86_64-33-1.2.iso. Ventoy is an open source tool that lets you create a bootable USB drive for ISO files. The latest Ventoy 1.0.40 adds persistence support for Fedora and Arch Linux (including ArchMan, ArchBang, BlackArch, etc.). Also, you can upgrade Ventoy without having to reformat the USB disk.

Ventoy supports both legacy and UEFI Secure Boot, it has persistent support for some Linux distributions, it has auto-installation support (for Windows and Linux distributions that support this), and it supports ISO files larger than 4 GB. So you can copy other files to the USB, and it won't interfere with Ventoy.

What's more, since you don't need to format the USB drive, you can continue to use it for other purposes. You can copy as many ISO files as you wish (even combined Windows and Linux ISOs), and when booting from the USB, Ventoy shows a list of available ISO files, allowing you to boot from the one you select. You need to install Ventoy to a USB drive, then every time you want to create a bootable USB drive, all you have to do is copy the ISO to the USB. Ventoy is available for Microsoft Windows and Linux, and it can create bootable USB drives containing Linux and Windows ISO files. Ventoy, a tool to create a bootable USB drive by simply copying the ISO to the USB, has been updated to version 1.0.40, bringing support for creating persistent USB drives for Fedora and Arch Linux (including ArchMan, ArchBang, BlackArch, etc.).
