How to create a Windows 8.1 bootable USB
Because Windows 8.1 is an older operating system, it is often downloaded for testing. Creating a bootable USB for testing across different computers is usually unnecessary and inconvenient.
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.
Steps
- Connect a clean USB drive or external hard drive to the Windows 8.1 computer.
Ensure the drive capacity is larger than the OS partition; otherwise, the cloning process will fail. - Download, install, and open iBoysoft DiskGeeker for Windows.
- The Windows 8.1 system partition will automatically appear in the Source OS disk section.
- Click "Select a destination disk" and choose the USB drive or external disk.
- Click "Start" and confirm the prompt to begin cloning.
After cloning is complete, the bootable Windows 8.1 copy can be connected to compatible computers for testing or used to start a PC that fails to boot.
Use Rufus to create a Windows 8.1 bootable USB
If you need a Windows 8.1 bootable USB for system recovery or reinstallation, you can use Rufus to complete the task.

- Connect a USB drive with at least 16 GB of storage for 32-bit Windows 8.1 or 20 GB for 64-bit.
- Launch Rufus and select your USB device.
- In the Boot selection section, choose the downloaded Windows 8.1 ISO file.
- Complete the required configuration.
- Click "START."
- Follow the on-screen instructions to finish creating the bootable USB.
