Grub v0.97 doesn't display new boot options after editing menu.lst file

I recently installed Android x86 7.1-r3-i386 in a partition in the same hard drive my Debian 10 i386 system is. I edited /boot/grub/menu.lst to add a new option to run Android x86 in the boot menu. But after running update-grub and rebooting my computer the new entry doesn't show. Here is the content of /boot/grub/menu.lst > # menu.lst - See: grub(8), info grub, update-grub(8) > # grub-install(8), grub-floppy(8), > # grub-md5-crypt, /usr/share/doc/grub > # and /usr/share/doc/grub-legacy-doc/. > > ## default num > # Set the default entry to the entry number NUM.
