Easily write raw image files to USB with Win32 Disk Imager. This utility uses low level raw read and write functions to directly copy data to or from a device. For example, it can be used to copy an ISO or IMG file to a USB drive. Or instead used to create a backup image of a device. It also features a built in file checking option to check for file corruption before writing a file. This image writing software is available portably as a zipped file.

Using Win32 Disk Imager to write an ISO Image to USB
In the example below, I am using the Image Writer to put a Rescatux Live ISO on a USB flash drive.
1. Download the zipped version of Win32 Disk Imager.
2. Extract (Unzip) the contents to a folder to your desktop.
3. From within that extracted folder, right click the Win32DiskImager.exe file and select (Run as Administrator).
4. Then once the program is up and running;
(1.) Browse to and choose your ISO file. You may need to allow *.*
(2.) Choose your destination device.
(3.) Click Write.
5. Upon completion, see if the drive works as intended.
In the case above, a Rescatux ISO was written to USB. So the drive should act just like a CD-ROM and boot right into that Live operating environment. Assuming that I reboot my computer and set my BIOS or UEFI boot menu to boot from the USB device.
