2 Free methods to burn ISO to USB in Windows 10
Different from copying and pasting files, burning Windows 10 ISO to USB is more complicated since the USB drive needs to be bootable once you got the ISO images onto it. Fortunately, there are still two methods available to help you copy ISO to the USB drive in Windows 10.
▌Method 1. Copy ISO to USB via Windows native "Windows To Go"
To burn ISO files to USB in Windows 10, if you are mainly running Windows 10 Education/Enterprise/Pro, you can use its built-in "Windows To Go" feature, which allows you to create a Windows To Go workspace that can boot a computer from the certified USB drives. Here is how to perform it.
Step 1. Download ISO files from Microsoft official website and connect a certified USB drive (at least 32 GB) to your computer.
Warning: Burning an ISO image to a USB drive will delete all data on the drive. So please check that you plug in an empty USB drive or that you have backed up any files that you don’t want to lose before proceeding to the following steps.
Step 2. Open Control Panel on your computer, and search “Windows To go” in the window. Then click the “Windows To Go” feature.
Step 3. In the next window, it will automatically search for the inserted USB drive. After that, click the USB drive you plan to burn ISO onto and then “Next” to continue.
Note: Only when the USB drive meets the required hardware specifications of Microsoft, the “Next” button can be clickable. Or you will encounter the above error message.
Step 4. Click “Add search location” to search for the Windows 10 installation ISO file and choose the mounted ISO file.
Step 5. In the subsequent window, you can enable BitLocker Drive Encryption on your Windows To Go workspace, which can protect valuable data on the USB drive.
Step 6. Finally, Windows 10 will actually move the Windows 10 ISO image to the USB drive.
