How to Install Windows 11 on USB Drive

This guide will walk you through the process of creating a bootable USB drive for Windows 11. This is useful for installing the operating system on multiple devices or for creating a portable Windows environment.

Step 1: Download Windows 11 ISO File

Go to the official Microsoft website and download the Windows 11 ISO file.

Ensure you select the correct version based on your system requirements. This file will be essential for creating your bootable USB drive.

Step 2: Format Your USB Drive

Insert your USB drive into your computer and format it to FAT32 or NTFS.

Formatting your drive ensures that it’s clean and ready for the Windows 11 installation files. Be aware that this will erase all data on the USB drive.

Step 3: Download and Install Rufus

Download Rufus, a free utility that helps in creating bootable USB drives, from its official website.

Rufus is user-friendly and supports a variety of file systems, making it an ideal choice for this task. Once downloaded, install it on your computer.

Make sure you choose the correct drive, as selecting the wrong one could overwrite important data on another drive.

Step 5: Select Windows 11 ISO File in Rufus

Click on the ‘Select’ button in Rufus and browse to the Windows 11 ISO file you downloaded.

Choosing the ISO file tells Rufus what files to use when creating the bootable USB drive. Ensure you pick the correct file to avoid errors.

Step 6: Configure the Partition Scheme and File System

Set the partition scheme to ‘GPT’ and the file system to ‘NTFS’ in Rufus.

These settings ensure compatibility with most modern computers and allow for larger file sizes, which are common in operating system files.

Step 7: Start the Process

Click ‘Start’ in Rufus to begin creating your bootable USB drive.

Rufus will alert you that it will erase all data on the USB drive. Confirm to proceed, and the process will start. This may take several minutes.

Once you complete these steps, your USB drive will contain a bootable version of Windows 11. You can now use it to install the operating system on any compatible computer.
