Rufus

Rufus is a utility that helps format and create bootable USB flash drives, such as USB keys/pendrives, memory sticks.

It can be especially useful for cases where:

you need to create USB installation media from bootable ISOs (Windows, Linux, UEFI, 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 everything you need.

Oh, and Rufus is fast.
