You can create bootable USB devices of linux distribution & Windows with target system as UFEI or BIOS.

The project is highly inspired by Rufus which is written in C++. The windows version is written in C# and Linux with JavaFx. My main reason to create this project is to learn these languages and to practically understand how they work, such type of project inspired me a lot.

Iso2Usb is bit faster than Rufus ( I guess with only 8 seconds difference tested with Elementary OS Juno) & UnetBootIn.
