Ventoy enthusiasts and Windows users have reason to celebrate: the release of Ventoy 1.1.03 promises to resolve a persistent Windows 11 installation error while ironing out a few other boot-related wrinkles.

Introduction​

For many power users and system administrators, creating bootable USB media for installing operating systems is a routine—yet critical—task. Ventoy, the popular open-source tool, has become a go-to solution due to its flexibility in handling multiple ISO files on a single USB drive. However, with the rollout of Windows 11 version 24H2, users began reporting a disturbing installation hiccup: an error message featuring the code 0x80070001 - 0x4002F.
This error typically appears after accepting the license agreement and during partition selection, effectively halting the installation process. Ventoy 1.1.03 directly addresses this glitch along with a few other boot issues, making it an update that merits close attention for anyone engaged in Windows installations using bootable media.

Understanding the Windows 11 Installation Error​

What Was Happening?​

Users attempting a fresh installation of Windows 11 (specifically the 24H2 release) via Ventoy encountered an error immediately after confirming the license agreement and selecting the partition. The system would display a message similar to:

Windows 11 Setup
Windows installation encountered an unexpected error. Error code: 0x80070001 - 0x4002F

This error code (0x80070001) is not uncommon in the realm of Windows installations, where it typically hints at underlying file system or boot configuration issues. In this context, the error appears to have been linked to Ventoy’s handling of boot files during the setup process.

How Does the Update Help?​

By addressing the error directly within its boot management code, Ventoy 1.1.03 modifies the approach used to initialize the installation process. Although the detailed internals remain under the hood, the outcome is clear: the installation process now bypasses the glitch that previously led to an abrupt termination of Windows Setup.

A Closer Look at Ventoy’s Role​

What is Ventoy?​

For those who might be new or returning to the discussion:

• Ventoy is an open-source tool that allows for the creation of bootable USB drives that can host multiple operating system installation files.
• Unlike traditional tools such as Rufus, which require reformatting and rewriting the USB drive for each ISO, Ventoy’s design lets you simply copy ISO files onto the drive. When booted, Ventoy presents a menu of available images, making the installation process more flexible and efficient.

This design makes it especially popular among Windows users who frequently test different OS distributions or tools, as well as IT professionals managing multiple builds and deployments.

Why It Matters for Windows 11 Installations​

The upgrade to Windows 11 24H2 brought new features, interface changes, and improved security measures—but it also introduced new compatibility challenges. The persistent installation error disrupted workflows and forced many into a trial-and-error loop with various installation tools. Ventoy’s update comes as timely relief, reaffirming its reliability as a bootable media solution.

Navigating the Updated Executable and Antivirus Warnings​

One noteworthy change in Ventoy 1.1.03 is an updated executable file. While this update is central to the improvements, it has raised concerns among some users: antivirus software may flag the new executable as a false positive.

Best Practices to Mitigate False Positives:​

• Download from Official Sources:
  Always ensure that you are downloading Ventoy directly from its ventoy - Overview, where you can verify the file’s integrity and authenticity.
• Check Digital Signatures and Hashes:
  Compare the digital signature and file hash values provided on the official download page with the ones on your copy. This extra verification step can help prevent inadvertent execution of tampered software.
• Temporarily Adjust Antivirus Settings:
  If your antivirus flags the updated executable, consider temporarily disabling the scan for that session—but only after ensuring the file is from a trusted source. Re-enable your antivirus immediately after the verification process.
• Consult Community Feedback:
  Engage with user forums and threads (for example, Windows 11 Snipping Tool Now Includes Video Trim Feature) to see how others are handling these warnings. Community-sourced tips and experiences can be invaluable.
