Fix: “We Were Unable To Copy Your Files. Please Check Your USB Device And The Selected ISO File” Error In Windows 7 USB/DVD Download Tool

Earlier this week, I installed Windows 7 on my laptop in dual boot with Windows 8.1. While preparing the bootable USB of Windows 7 using Microsoft USB/DVD Download Tool, I got “We were unable to copy your files. Please check your USB device and the selected ISO file and try again” error. More often than not I use the ever-green Command Prompt or the popular Rufus tool to install Windows 7 from USB drive. However, this time, I thought of using the official Windows 7 USB/DVD Download Tool that I had downloaded earlier to check if it’s compatible with Windows 10. Those of you getting “We were unable to copy your files. Please check your USB device and the selected ISO file and try again” error while preparing Windows 7/8/10 bootable USB can use a more efficient third-party tool such as Rufus to prepare the bootable USB. The download size of Rufus is under 1 MB, and more importantly, you can run the tool without having to install it.
