Win32DiskImager | Write ISO Image to USB


Use Win32DiskImager to Write images to USB drives. This USB Imaging utility uses low level raw read and write functions to DD or directly copy data to or from a device. For example, it can be used to copy an ISO or IMG file to a USB flash drive. It might also be used to create a backup image of a device.

What is Win32DiskImager?

Win32DiskImager is an open source application that allows users to write raw disk images or ISO files to removable storage devices, such as USB drives or SD cards. It is primarily used for creating bootable USB drives or SD cards for operating systems like Linux or for burning disk images of various software distributions.

Here are some of its key features:

  1. Creating Bootable USB Media: Used to write bootable images of operating systems onto USB drives or SD cards. This is commonly done for installing or repairing operating systems.
  2. Cloning and Backing Up Drives: Users can create exact copies of removable storage devices, allowing for easy cloning or backing up of data.
  3. Open Source: It is also open sourced software, which means that its source code is freely available to the general public. This allows users to view and redistribute or even modify and contribute to its development.

This intuitive utility features a built in file checking option to check for file corruption before writing a file. The image writing software is available portably and standalone as a zipped file. So you can bring it with you on a removable device to then run from any available Windows Computer.

  5. Upon completion, reboot from your USB drive to make sure it works as intended.

In this example, the ISO Image Writer was used to put a Rescatux Live ISO on a USB flash drive. Since a bootable ISO was written to USB, the drive should act just like it would booting from a CD-ROM and boot right into the Linux Live operating environment. Simply reboot the computer, set your BIOS or UEFI to boot from a USB drive, and then proceed to boot from the Live USB.
