Grub2 does not detect my wifi slax OS

I have installed wifi slax OS from a usb on a partition along side with windows 10 and the installation process install also grub2 when finished I reboot and grub2 show only windows 10 loader. So, how I can list all available OS to boot? my grup.cfg file contains: ---------- # # DO NOT EDIT THIS FILE # # It is automatically generated by grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### if [ -s $prefix/grubenv ]; then set have_grubenv=true load_env fi if [ "${next_entry}" ] ; then set default="${next_entry}" set next_entry= save_env next_entry set boot_once=true else set default="0" fi if [ x"${feature_menuentry_id}" = xy ]; then menuentry_id_option="--id" else menuentry_id_option="" fi export menuentry_id_option if [ "${prev_saved_entry}" ]; then set saved_entry="${prev_saved_entry}" save_env saved_entry set prev_saved_entry= save_env prev_saved_entry set boot_once=true fi function savedefault { if [ -z "${boot_once}" ]; then saved_entry="${chosen}" save_env saved_entry fi } function load_video { if [ x$feature_all_video_module = xy ]; then insmod all_video else insmod efi_gop insmod efi_uga insmod ieee1275_fb insmod vbe insmod vga insmod video_bochs insmod video_cirrus fi } insmod part_msdos insmod ext2 set root='hd0,msdos7' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos7 --hint-efi=hd0,msdos7 --hint-baremetal=ahci0,msdos7 68c96891-4e12-46ff-a9c5-b8c46a361698 else search --no-floppy --fs-uuid --set=root 68c96891-4e12-46ff-a9c5-b8c46a361698 fi if loadfont /usr/share/grub/dejavusansmono.pf2 ; then set gfxmode=auto load_video insmod gfxterm set locale_dir=$prefix/locale set lang=en_US insmod gettext fi terminal_output gfxterm insmod part_msdos insmod ext2 set root='hd0,msdos7' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos7 --hint-efi=hd0,msdos7 --hint-baremetal=ahci0,msdos7 68c96891-4e12-46ff-a9c5-b8c46a361698 else search --no-floppy --fs-uuid --set=root 68c96891-4e12-46ff-a9c5-b8c46a361698 fi insmod gfxmenu loadfont ($root)/boot/grub/themes/Wifislax/Sans-10.pf2 loadfont ($root)/boot/grub/themes/Wifislax/Sans-12.pf2 loadfont ($root)/boot/grub/themes/Wifislax/Sans-14.pf2 insmod png set theme=($root)/boot/grub/themes/Wifislax/theme.txt export theme if [ "${recordfail}" = 1 ] ; then set timeout=30 else if [ x$feature_timeout_style = xy ] ; then set timeout_style=menu set timeout=10 # Fallback normal timeout code in case the timeout_style feature is # unavailable. else set timeout=10 fi fi ### END /etc/grub.d/00_header ### ### BEGIN /etc/grub.d/10_linux ### function gfxmode { set gfxpayload="${1}" } set linux_gfx_mode= export linux_gfx_mode ### END /etc/grub.d/10_linux ### ### BEGIN /etc/grub.d/20_linux_xen ### ### END /etc/grub.d/20_linux_xen ### ### BEGIN /etc/grub.d/30_os-prober ### menuentry 'Windows 10 (loader) (on /dev/sda1)' --class windows --class os $menuentry_id_option 'osprober-chain-EC023C1B023BE96A' { insmod part_msdos insmod ntfs set root='hd0,msdos1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1 EC023C1B023BE96A else search --no-floppy --fs-uuid --set=root EC023C1B023BE96A fi parttool ${root} hidden- drivemap -s (hd0) ${root} chainloader +1 } set timeout_style=menu if [ "${timeout}" = 0 ]; then set timeout=10 fi ### END /etc/grub.d/30_os-prober ### ### BEGIN /etc/grub.d/30_uefi-firmware ### ### END /etc/grub.d/30_uefi-firmware ### ### BEGIN /etc/grub.d/40_custom ### # This file provides an easy way to add custom menu entries.
