scrips para añadir ventoy a GRUB 2

https://github.com/BWGosselin/Ventoy_GRUB_Entry/issues/1

he instalado ventoy en mi disco duro interno y en otra partición he instalado debian 12 pero debian machaca el mbr y solo puedo arrancar debian, quiero incluir en grub2 el ventoy instalado en el disco duro , qué solución puede haber para tener arranque de ventoy   desde mi debian12??

por desgracia es para detectar ventoy en stick USB no me funciona al tenerlo instalado en mi disco duro interno ventoy . sería para tener ventoy y una instalación de Linux completa en mi disco duro interno y operativos en ordenadores algo antiguos que no dividen el arranque de ventoy y la instalación completa de Linux en UEFI.

este es el script: 

#!/bin/bash

# Enhanced echo with background colors for clear visual differentiation

echo_color() {

    local msg=$1

    local color=$2

    case "$color" in

        red) color_code="41;37" ;;     # White text on red background

        green) color_code="42;30" ;;   # Black text on green background

        yellow) color_code="43;30" ;;  # Black text on yellow background

        *) color_code="0" ;;           # Default to no color if not specified

    esac

    echo -e "\\033[${color_code}m${msg}\\033[0m"

}

echo_color "Script Initialization..." yellow

sleep 1  # Short pause for user to read the message

# Confirm start

echo -n "This script will modify system configurations. Continue? (y/n): "
