How to create a Windows 8.1 bootable USB

As an older Windows release, Windows 8.1 is commonly downloaded for testing purposes. Creating a bootable USB for testing across multiple machines is usually unnecessary and time-consuming.

Instead, you can use iBoysoft DiskGeeker for Windows to clone the OS partition (C: drive) from a Windows 8.1 computer. This gives you a bootable Windows 8.1 copy that can be used on multiple compatible PCs without any extra configuration.
