Boot DOS from USB – RUFUS

Creating a Bootable USB Flash drive to “Boot DOS from USB“, can be complicated. However, a tool called Rufus, created by Pete Batard, can make this task simple. Rufus can also be used to create a Bootable USB version of a given distro from an ISO or image File. Rufus was originally similar in appearance and operation to the HP USB Format tool “HPUSBFW.exe”, and shares many of the same features. However, Rufus is Open Source.
