Rufus Portable

Rufus is a simple application that lets you convert any pen drive into a bootable USB drive with which you can start in MS-DOS.

This portable version does not require installation, you just have to run the program and insert the USB device. You can configure the format type and the file system, among several other options, and then press the start button. In a few second you’ll have your bootable USB drive ready to go.

Rufus Portable is tremendously simple to use and lightweight, it works really well and barely uses any roesources. It is, without a doubt, a great option for those who need to start in DOS.
