If you often work with multiple ISO files, Ventoy might be the ideal solution for you.I use this tool all the time now.I used to use unetbootin and universal USB installer or YUMI for multiple OSs on a disk or Rufus or etcher all those tools are great but none of them are as handy as ventoy.with ventoy I can creat a USB drive with a massive partition for many ISOs(Im a system technician so I have needs beyond those of your average user lol) I need windows,Linux,MacOS, and some times freedos to be able to effectively service the wide veriaty of my clientele, be that Enterprise or consumer systems and this tool allows me to do that efficiently and with little messing around.I currently have a 256gb usb3.2 SSD setup with a massive ISOs partition that holds all the iso I could ever need and still have a large section on the drive for a persistent Area I use this for a full Manjaro xfce install that I can use to go grab new ISOs and drop them into the ventoy partition for later use and to also act as my shared storage that is accessable and writeable from any of the ISOs live environments.in all my years of trying all of these 'pendrive' type tools NONE of them come close to the veriaty of capabilities that ventoy has, it supports every archetecture iv tryed it on be that 64bit, 32bit, uefi, legacy, name it it works. The developer keeps improving the product, adding support for new systems and resolving existing issues. This program is powerful and dramatically facilitates booting and installation processes. Since convenience is the name of the game with this tool, you don't need to manually update your program with each new upgrade, either. It displays available options on clearly-labelled fields and ISO options in lists or a tree view.

While it doesn't have the most fashionable look, Ventoy features a straightforward, smooth interface. It also supports Secure Boot, Persistence for Linux, and auto-installation for additionally customising your configuration. This program can perform Legacy BIOS and UEFI booting, which significantly increases the available operating system options. You can click on the one you wish to use and wait for the process to finish. Ventoy will offer you a selection menu with over 470 available ISO files across several major operating systems (for now, with more to come). You can then place ISO images on your USB.

All you need to do is choose your USB and click the Update button, and the program will boot your device.

Once you download and launch the file, it will open a window showing you a list of available setup locations. Ventoy's installation process is straightforward.
