Ventoy Custom Wallpaper Setup 🔥 Add Your Branding

Prepare Your Ventoy USB and Branding Image

Start with a USB drive that already has Ventoy installed and working — this tutorial only changes how the Ventoy boot menu looks, not how Ventoy itself is installed. Keep your branding image ready: your shop logo, channel logo or any wallpaper you want on the boot screen, saved as a PNG or JPG image. A 1920x1080 image works best, because that is the resolution most boot screens run at.

Open the Ventoy Drive and the ventoy Folder

Plug the Ventoy USB into your PC and open the main Ventoy partition in File Explorer — the large data partition where your ISO files are stored. Ventoy reads all of its extra configuration from a folder named ventoy in the root of this partition. If the folder is not there yet, create it with exactly this name, all in lowercase.

Copy the Theme Folder into ventoy/theme

Inside the ventoy folder, create a folder named theme. Now copy your complete theme folder into it, so the path looks like ventoy/theme/MyTheme/. A theme folder contains everything the boot menu needs: the theme.txt file, which is the GRUB2 theme file that describes the menu layout and points to the background image, along with the image itself, fonts and icons.

Replace the Background Image with Your Branding

Open the theme folder you just copied and find the background image that theme.txt uses — in most themes it is named background.png. Replace that file with your own branding image, keeping the same file name and the same format. Because the theme file keeps pointing to the same name, Ventoy now loads your logo or wallpaper as the boot screen background, with the theme's menu layout on top of it.

Activate the Theme in ventoy.json

Finally, tell Ventoy which theme to load. In the ventoy folder, create a file named ventoy.json (or open it if it already exists) in Notepad and add the theme section below. The file value is the full path of your theme.txt on the USB, and gfxmode is the resolution the boot menu should run at:

{
    "theme": {
        "file": "/ventoy/theme/MyTheme/theme.txt",
        "gfxmode": "1920x1080"
    }
}

💻 Key resolution steps from the video: theme.txt and ventoy.json — the theme file defines the look, and ventoy.json is what switches your theme on.

Boot from the USB and Check the Result

Safely eject the USB, plug it into the PC you want to boot, and select the USB from that PC's boot menu. The Ventoy menu now opens with your custom wallpaper and your own branding on the boot screen. If the default Ventoy theme still appears, eject the drive and re-check the two things that usually go wrong: the file path inside ventoy.json, and the background image's file name inside the theme folder.
