The standard way to clean install any Microsoft Windows operating system on a device is from a bootable USB drive, which contains a downloaded ISO image on it. Installing Windows 11 is not an exception, either. Do you know how to create a Windows 11 bootable USB drive with an ISO image? What if you don't have any ISO image files available to download?

In the previous post, we discussed how to create a Windows bootable drive with Rufus, a free and open-source application for installing Microsoft Windows. It's like to image a bootable ISO file to an external USB device, but the premise is that you've downloaded the ISO file by yourself. Therefore, Rufus is one way you can follow to create a Windows 11 bootable USB drive, but we got you a better and more foolproof method to install Windows 11 with ISO to a portable USB drive.

The Best Way Ever to Create a Windows 11 Portable USB Drive with ISO

Compared with Rufus, the upcoming method can be a perfect one. EaseUS Win11Builder completely solved the problem for all inexperienced Windows users who are unable to find and download an official Windows 11 ISO file. In short, with the EaseUS bootable USB creation tool, all you need is to prepare an empty USB flash drive or any other type of external USB device and give it time to automatically install the ISO image to the USB drive for you. 

Step 1. The Win11 builder is integrated with the EaseUS OS2Go software. Click the download button and launch the program after installation.

The Other Different Way to Make Windows 11 Bootable USB Drive Without ISO
