Rufus is a small utility desktop that helps format and create bootable USB flash drives, such as USB keys/pendrives, memory sticks, etc.
It can be be especially useful for cases where:
- you need to create USB installation media from bootable ISOs (Windows, Linux, etc.)
- you need to work on a system that doesn´t have an OS installed
- you need to flash a BIOS or other firmware from DOS
- you want to run a low-level utility
Despite its small size, Rufus provides you with everything you need!
Remember that once formatted, your drive is still usable as before to transfer data: it doesn´t have to be dedicated for DOS or ISO installation only.
