What You Should Do When WinToUSB Not Working
When WinToUSB is not working, you can try these steps to fix and create your bootable Windows USB drive.
WinToUSB is a free tool that allows you to install and run your own Windows 11/10/8.1/8/7 OS on an external hard drive or USB drive. Unlike the feature of Windows 8/8.1/10 Enterprise, Windows To Go, it does not require Microsoft certified USB drives and it supports all versions of Windows 11/10/8/7.
You can create a removable Windows workplace on a USB device from an ISO image file, CD/DVD drive, or your current Windows OS. However, there are times when WinToUSB fails to work. If you cannot make the WinToUSB work, you can check a few things below:
1. The source image file is corrupted. If you want to create Windows bootable USB from an ISO/WIM/ESD/SWM/VHD/VHDX file, make sure the image file is valid. Otherwise, you may get the error "Copy file failed. (0x0000008000B40000)".
2. Win7 to USB 3.0. As you know, Windows 7 does not have built-in support for USB 3.0, so you can only boot Windows 7 from a USB 2.0 drive.
3. Partition is not active. After you create a Windows portable USB, you need to set the system partition as active in Disk Management or third-party . Needless to say, you need to set the USB bootable drive you created as the first boot device before booting from it.
If it still fails to work or WinToUSB is stuck at 0 after checking these steps, you can try a free alternative to WinToUSB.
