ISO to USB: How to Burn ISO to USB in Windows 10

Updated by Daisy on Jan 21, 2022

Burning the Windows 10 ISO file to a USB is an inevitable step when you want to install Windows from a USB or create a bootable USB drive. However, burning ISO to a USB is just one of the many steps to achieve your goal of creating a Windows 10 installation disk. For example, after burning the ISO file to the USB flash drive, you will further need to download the Windows USB/DVD download tool to finish the remaining procedure. Luckily, there is an alternative way to create a bootable disk for Windows 10, which is far more effective than burning ISO to a USB in Windows 10.  Apply one of the two methods below according to your needs:

Easier Way: Create a Windows 10 Bootable USB Drive

If your purpose is to create a bootable USB drive which you can boot Windows 10 from, don't bother burning the ISO file to a USB anymore. With the Windows backup software - EaseUS Todo Backup, you can make your Windows 10 portable in only three steps, sparing you from downloading the ISO file, burning the ISO file to the USB, and more.

USB requirements:

1. Check how much disk space is used for the system C drive. Let's assume 40GB. Then prepare a qualified USB drive, of which the disk capacity must be larger than 40GB.

2. Do you use an empty new USB drive or an old one? Make sure that all the important data has been safely transferred because the system clone will overwrite data on it completely.

3. Correctly connect the USB drive to your machine and make sure that Windows has detected it and assigned a drive letter to it.

Follow the overall process to create a portable Windows USB drive and boot from it:

Step 1. Launch EaseUS Todo Backup. Expand the Tools menu and click "System Clone".

select system clone

Step 2. On the "System clone" window, the software will choose the system partition and boot partition by default. Just Choose the USB drive as the destination disk. Click on "Advanced options" and then "Create a portable windows USB Drive". Click "OK" and then "Next".

select system clone

Step 3. You can preview or adjust the disk layout on the destination drive. If there is no problem, click "Proceed" and the software will start immediately cloning the default system partitions of your desktop/laptop to the USB drive. After the cloning process is over, you can safely plug the USB drive out.

select system clone

Step 4. Boot from the USB drive.

  • Connect your portable USB to the computer
  • Restart the computer and press "Del" to enter BIOS
  • Set the PC to boot from the portable USB by changing the boot order in BIOS under the "Boot" tab
  • Save changes and you'll see your system booting up from the USB drive

Being different from burning a downloaded Windows ISO file to a USB flash drive, EaseUS Todo Backup allows you to create a bootable Windows 10 USB directly. Besides, if you want to install Windows 10 from the USB by burning ISO to the USB and then creating a Windows 10 installation disk, this software can also provide you a much more convenient way to install Windows 10 on your computer, that is to migrate Windows 10 from another computer without reinstallation. 

Another outstanding feature you may need is to create an emergency USB. With it, you can boot your computer with the USB and rescue your data when the computer fails to boot properly.

EaseUS Todo Backup is an unmissable tool for you to protect your important data, whether it's on your computer, external hard drive, USB flash drive or other external storage devices. Try it and you will know how useful it is.

How to Burn ISO to USB in Windows 10

To burn ISO to a USB in Windows 10, a third-party tool is necessary since it's not simply copying and pasting. In addition, depending on where the ISO file is, for example, on your computer or in the Windows 10 installation DVD, you will have different approaches to burn the ISO file to the USB.  If you have downloaded the Windows 10 ISO file on your computer, you can apply the ISO to USB burner such as Rufus to burn ISO to USB flash drive. Go to visit Rufus (https://rufus.ie/) and download the latest version of Rufus. After that, double-click the .exe file to launch Rufus and connect your USB to your computer. Then:

Step 1. From the Device drop-down menu, choose the USB device you want to burn the ISO file to.

Step 2. From the Boot selection drop-down menu, choose "Disk or ISO image (Please select)", then click "SELECT" and choose the ISO file stored on your computer.

Step 3. To ensure you can boot from the USB on both UEFI and BIOS computer, choose "MBR" under Partition scheme, 

Step 4. Leave the other options unchanged and click "Start" to begin burning the Windows 10 ISO file to the USB drive.
