# Grub2Win Boot Entry Missing

If your PhoenixOS DarkMatter grub2win entry is missing from the boot-menu then you can follow this.

Open C:/grub2/grub.cfg with a text editor (Notepad++)
Copy and paste this code at the bottom of that file.

#  Sub Menu Entry       DarkMatter-Exo4.7
#
submenu   'DarkMatter-Exo4.7'  --class submenu --class icon-asg {
     #
     source $prefix/windata/customconfigs/DarkMatter-Exo4.7.cfg
     #
}

Download the file below and copy in C:/grub2/windata/customconfigs
