How to create USB bootable from an ISO image.

You have an ISO image and you want to use USB as an installation media, then for this you need to create a USB bootable. 

We have a tool in the name of Rufus free available on net which create your ISO image to bootable one. 

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

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!

With the use of this software, we can also create Linux bootable USB from ISOs

Also, we can flash the BIOS and other low level utility on a system that doesn’t have any OS installed.

 

Notes on DOS support: 

If you create a DOS bootable drive and use a non-US keyboard, Rufus will attempt to select a keyboard layout according to the locale of your system. In that case, FreeDOS, which is the default selection, is recommended over MS-DOS, as it supports more keyboard layouts.

Notes on ISO Support: 

All versions of Rufus since v1.1.0 allow the creation of a bootable USB from an ISO image (.iso).

Creating an ISO image from a physical disc or from a set of files is very easy to do however, through the use of a CD burning application
