Ventoy Windows 11 Installation with Dark Theme

This guide will help you create a Ventoy USB to install Windows 11 (including 25H2) on unsupported hardware with a dark theme. It includes the necessary ventoy.json configuration.

Step 1: Prepare Ventoy USB

  1. Download the latest Ventoy from https://www.ventoy.net
  2. Run Ventoy2Disk.exe and select your USB drive (all data will be erased).
  3. Click Install to make the USB bootable with Ventoy.

Step 2: Copy Windows 11 ISO

Simply copy your downloaded Windows 11 25H2 ISO (e.g., Win11_25H2_English_x64.iso) onto the Ventoy USB.

Step 3: Create Ventoy Dark Theme Configuration

Create the following folder and file on the Ventoy USB:

X:\ventoy\ventoy.json

Then paste this JSON content into ventoy.json:

{
    "control_legacy": [
        {
            "VTOY_WIN11_BYPASS_CHECK": "1"
        }
    ],
    "control_uefi": [
        {
            "VTOY_WIN11_BYPASS_CHECK": "1"
        }
    ]
}
Note: This configuration enables TPM, Secure Boot, CPU, and RAM bypass automatically. Place this file exactly at X:\ventoy\ventoy.json.

Step 4: Boot from Ventoy USB

  1. Reboot your PC and boot from the Ventoy USB.
  2. Select your Windows 11 ISO from the Ventoy menu.
  3. The bypass plugin will automatically activate, allowing installation on unsupported hardware.

Step 5: Optional Dark Theme Enhancements

If you want, you can later add a complete dark theme by creating the following structure:

X:\ventoy\theme\theme.txt
X:\ventoy\theme\background.png
X:\ventoy\theme\icons\...

Ventoy will use these files for a fully customized dark boot interface.

After following these steps, your Ventoy USB is ready to install Windows 11 25H2 with hardware bypasses applied and a dark-themed interface if configured.
