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".

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".

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.
