An ISO file is an archive file that contains an identical copy of a data on an optical disc; that is why ISO files are also known as ISO image. The generation of CDs and DVDs are long gone; people are often using a flash drive to transfer files.

But nowadays, we don’t find Disc drive on laptops, and hardly can we find them on desktops. Today, I am writing about how to burn ISO file on a USB flash drive using the Windows operating system.

Burning ISO file on a USB Drive
Here I will be explaining two different ways you can choose to burn ISO file on a USB Flash Drive. The first method is by using Windows feature, command prompt. Command Prompt is a command-line interpreter application available in most of the Windows operating systems. And the second method is by using a software “Rufus.” Rufus is a user-friendly application that requires you to download on to your system. However, these methods are only useful when you don’t have your burned USB flash drive beforehand; or you will burn another ISO file on a USB Flash Drive. In burning Windows 10, the Windows 10 Setup wizard will do the burning work for you without having you to download Rufus or use the command prompt.
Method 1: How to Burn ISO file on a USB Flash Drive Using Command Prompt
- Insert your USB flash drive that you want to burn ISO file on. [Note: Make sure your USB flash drive has enough space to copy the ISO image file],
- Run Command Prompt as Administrator. Got to run (Windows + R) and type cmd and click the Ok button.
- Type diskpart in the command prompt windows and hit Enter; this will launch Diskpart inside the command prompt interface.
- Once the diskpart program launches, type list disk and hit enter. List Disk will list all the active storage devices connected to your computer. This will list your hard drive partition, USB flash drive, and other storage devices if connected.
- Most of the time, Disk 0 will be your primary partition, that is your hard drive. Go through the list and find your USB flash drive. In my case Disk, 1 is my USB flash drive. To avoid confusion, always insert the only flash drive you want to burn the ISO file.
- In my case, I will select Disk 1, so I will type select Disk 1 because disk 1 is my USB flash drive. Replace 1 with the correct number for you “select Disk X” and Hit Enter. The disk you select will be the disk that diskpart controls in the next few steps. If everything you are doing is right, diskpart will render “Disk 1 is now the selected disk”.
- Before you Burn ISO file on a USB flash drive, you need to format the drive to make your USB flash drive bootable.
Type clear and hit Enter. This will erase all data on your flash drive, so keep your flash drive back up if there are any important files on it.
- After cleaning the drive, diskpart will render the successful message “Diskpart succeeded in cleaning the disk.” Now type create partition primary and press Enter. This is because once you clean the drive, the system recognizes the flash drive as unallocated space. Creating partition primary means that you will create a partition using the space where you will be going to burn the ISO file on.
- By default, diskpart will recognize the partition as partition 1. If you are confused, type list disk and hit enter; this will render disks and sizes and compare it with the listing you did in step 4.
Now, type select partition 1 to keep on working on it.
- Type active and hit Enter to activate the partition 1. This will render a successful message of activating the partition.
- Now, you will have to format the drive in NTFS format. Yes, we erased everything on the disk typing clear. However, this is different, and in this step, we are defining the partition type as NTFS.
- So, type format fs=ntfs quick and press Enter. This will take a while to complete.
- After formatting the drive is completed, type exit to leave the diskpart and exit your command prompt windows.
Now, your USB flash drive is formatted and ready for making it a bootable flash drive. You need to copy the installation files to the flash drive.
- Using the command prompt in this method, we can copy the installation files to the flash drive using CMD. The code for copying the file is “copy source destination /O /X /E /H /K.”
This might confuse you but there another simple option for you; go to the folder where you downloaded the ISO file. Now, right-click the ISO image and click Windows Explorer form the Open with option. This will open the files inside the ISO image file.
Now, please select all the files and copy it to your flash drive.
