How to Burn ISO to USB

Here, I am going to give a step by step procedure to burn an ISO file to USB Pendrive. So don’t miss the single step of it and read it carefully. Ensure that your USB device’s memory should have higher than the size of ISO file.

Step 1: First thing you need to do is to Download Rufus USB Tool, a free tool that will properly extract your ISO file and copying to your USB device, including any kind of files in the ISO file and you can use it as bootable device.

Where to get Rufus USB Tool –

Rufus USB is available on the official website of Rufus. It comes with two different variant of software which available in the official website. One is installed in your computer  then you can use it and other one is Rufus 2.11 Portable (916 KB), you can access it without installing. Installation process is not available so I recommend you to use Rufus Portable tool and it works on Windows 10, Windows 8, Windows 7, Vista, and Windows XP.

Note: Why we are highly recommend Rufus USB Tool, this is very fast. For instance it’s about twice as fast as UNetbootin, Universal USB Installer or Windows 7 USB download tool, on the creation of a Windows 7 USB installation drive from an ISO. It is also marginally faster on the creation of Linux bootable USB from ISOs

Step 2: After Downloading the Rufus 2.11 Portable tool and open it up. It doesn’t look complicated and only few options available on it, easy to understand as well. The Rufus Portable tool screenshot below.

You can also use Rufus 2.11.exe (916 KB) to install this tool on your computer but Earlier I said that you will Rufus Portable because it will not installed on your PC. Just you can open and use it after download.

Step 3: Then, Insert your USB Pendrive or any other USB drive to your computer which you want to burn.

Note: Make sure that the Burning process will erase all the data in the USB device. That is fine, if you are already formatted your USB Pendrive in some other way.

Step 4:  After Inserting the USB device or flash drive you want to “burn” the ISO file from your computer. Select your USB device in the Device part in the Rufus USB Tool.

This selecting process is not necessary if you’re inserted only one USB device in your computer because it will automatically detect the USB device.

The above image describing the selecting your USB device in the burning Tool. Click on it and  drop down menu will shown then, click on the USB drive you want to flash. This process is only for more than one USB devices inserted in your PC.

Step 4: Keep the Partition scheme and target system type, File system, and Cluster size as it is in the Tool unless you know what you are doing or you’ve been advised to set any of those parameters to something else.

Note: Don’t touch this part only if you the want file in FAT32 instead of NTFS on your USB. Otherwise leave this step.

Step 5: Next thing in the Rufus USB tool, you need to give a Volume Label name to your USB. For example if burning Windows 10 on the USB means I will give Windows 10 as Volume Label. You can give any name as Volume Label. It is not a major part of the tool. It is just a name that you are giving to your USB.

Step 6: Then, there is a Format Options in the USB burning tool, leave the Check devices for bad blocks and mark other three options including Quick Format, create a bootable disc using and create extended label and icon files.

Note: Why I am leaving the Bad blocks because 1 Pass is just fine in most cases but knock that up to 2, 3, or even 4 if you’ve had issues with this drive before.

Step 7:  Next to Create a bootable disk using, assure that ISO Image is selected and then click on the CD/DVD icon which is shown in the above screenshot.

Step 8: Manual work is almost complete, then last thing you need to do is click on Start button which is in the bottom of the tool.

Step 9: After click on the Start button, a warning message will popped-up look like this “WARNING: ALL DATA ON DEVICE ‘XYZ’ WILL BE DESTROYED” where it asks you to erase all your data. Then you need to click on OK button. Then it’s start burning to your USB.

Once the process is Done! Then your Pendrive or USB device will act as bootable device like DVD.

Do all the process carefully, I hope that you’re completely aware of how to make your USB device as bootable device. Then, you can go to Boot menu and give a first priority to USB drive.
