Troubleshooting the Common Issue of Stuck at 50% During Windows 11 USB Installation

Introduction

Battling with issues while creating a Windows 11 installation media can be frustrating, especially when you encounter the infamous 50% stuck point. This guide aims to provide insights and troubleshooting tips for users facing this common problem.

The Window's Media Creation Tool and Its Limitations

If you're currently using the Windows Media Creation Tool to download and install Windows 11 on a USB flash drive, you might have encountered a mysterious 50% hang-up. This issue isn't unique, and it's often more complex than a simple design flaw or a common bug. While Microsoft has not provided a permanent fix, there are several steps you can take to mitigate this issue.

Common Causes and Possible Solutions

The problem may stem from various factors, including:

Resource contention during the download and write process Temporary file issues or exclusive access by the USB drive Drive cleanup and defragmentation Compatibility and system settings affecting the tool's performance

Here are some detailed steps to help resolve the issue:

Step 1: Disk Cleanup

Before you start the Media Creation Tool, run a disk cleanup to remove temporary files and other detritus from the drive. This can help free up space and improve performance.

Step 2: Defragmentation

Ensure that your drive is defragmented if you're still using a hard disk drive (HDD). Defragmenting can improve write speeds, reducing the likelihood of the tool hanging.

Step 3: Create Contiguous Free Space

Regardless of whether your drive is an SSD or HDD, creating 8GB of contiguous free space can help the tool write the ISO more smoothly. Ensure that the space is not fragmented or scattered.

Step 4: Clean the Target Drive with diskpart

Before running the tool, use diskpart to clean the target flash drive. This ensures that any leftover data or fragments from previous installations are removed, minimizing the chances of the tool hanging.

Step 5: Disable Real-Time Antivirus and Other Utilities

Temporarily disable real-time antivirus scans and any other utility software that works in real-time. Real-time monitoring can interfere with the tool's ability to write to the USB drive correctly.

Step 6: Run in Safe Mode with Networking Support

Finally, try running the tool in safe mode with networking support to ensure that no other background services or drivers are interfering with the process.

Alternatives to the Windows Media Creation Tool

While the Media Creation Tool can be hit and miss, using alternative tools like Rufus can provide a more reliable and straightforward experience. Here's how Rufus can help:

Downloading Valid Image Versions

With Rufus, you can directly download valid image versions of all available Windows 8, 10, and 11 installations. This ensures that you're using an uncorrupted ISO file, which is crucial for a successful installation.

Creating the USB Installation Media

Rufus allows you to create the USB installation media in one seamless process, eliminating the need to download the ISO separately. The tool also provides features to check the integrity of the ISO file using its accompanying hash value, ensuring that the download was successful.

Conclusion

While the Media Creation Tool can be unreliable, the combination of manual steps and the use of Rufus can significantly improve your chances of creating a functional Windows 11 installation media.
