USBWriter is tiny Windows tool that lets you write an image file directly to an USB drive. It requires no installation and depends on no bloated framework, it's just a little program that you may put on your desktop.
This tool is useful to create a bootable USB disk from a Linux Live CD image file such as Ubuntu, Fedora, Gentoo or ArchLinux.
Please read the wiki in case of issues, every possible error or misbehavior is explained.
Can't run. Missing MSVCR110.dll (Microsoft Visual C++ Redistributable). Thus suggesting that the description is wrong.
Tiny and wrote a bootable ISO image to media with no problem. Very simple to use and works for USB attached drives (optical and flash, internal and external). An essential tool nicely coded.
