ISO is a popular file format being used on CD, DVD or Blu-ray Disc. The most common usage is for archiving operating systems like Windows, Linux or Unix. So once you burn an ISO image to an external disk such as USB flash drive, then you can directly boot it on your computer. It is quite useful if the computer has severe system issues or you simply want to reinstall the OS.


So, you have an ISO image file that you wish to burn on a USB flash drive. You may think, what the big deal in it, correct? Simply copy the ISO file and paste it on the flash drive and it's done! Well, sadly this is not the same scenario as copying other files on your flash drive. If you simply copy an ISO image file over a flash drive then you are just copying that exact file and not the content available in that ISO image file. If you try to boot on your PC using that theory then nothing will happen.


Fortunately, there are some free tools that can burn an ISO file to USB. You don't have to be an adept engineer or hire any headhunted technician to do this task. There are two amazing free tools available that can handle this job for you automatically. The complexity comes if you also want to boot from it. So in this article, we will show you how to burn an ISO to USB and make it bootable for operating system installation purpose.


Method 1: How to Burn ISO Image to USB drive by Using Rufus

Method 2: How to Burn ISO File to USB drive via ISO-to-USB


Method 1: How to Burn ISO Image to USB by Using Rufus

Rufus is a free utility tool that will perfectly create a bootable USB drive and extract all the content from the ISO image file and copy it over to the flash drive. You don't even need separate files to make it bootable as the necessary files will be present on that ISO image file.


Step 1: Download Rufus on your computer and the best part is, it doesn't need any installation. It is a ready-to-use program. Double click on rufus.exe and the program will launch immediately.


Step 2: Insert the flash drive into the computer in which you have just downloaded Rufus to burn the ISO image. Click on the drop down from the Device option and select the name of your flash drive.


Step 3: Use the default setting for Partition scheme and target system type, File system, and Cluster size unless you have the correct knowledge on what to do with them. But it is recommended to leave them as it is.

Method 2: How to Burn ISO to USB via ISO-to-USB

ISO-to-USB is yet another alternative for Rufus. This is also free program and the process and procedure to use this tool is more or less similar to Rufus. But if you are creating a bootable flash drive then this tool only works with Windows version.


Step 1: Download ISO-to-USB on your computer and launch the program.


Step 2: Click on "Browse" from the ISO file section and open the ISO image file. The file system can be both FAT32 and NTFS. FAT32 is recommended if you are not sure which one to choose.


Step 3: Enter any name on the "Volume Label" empty space. Click on "Bootable" if you are creating a bootable flash drive.

After finishing the burning process, the rest of the task is as simple as a piece of pie. Plug in the flash drive in any computer and start booting from it. You can make bootable flash drives using both programs and it works with the latest Windows 10 as well. As long you have an ISO image file, these two programs can easily burn and extract the files from them.
