1. Don't you have os-prober installed? Why is Ubuntu in the 40_custom section?

2. can you boot from Ubuntu if you add
insmod linux
between
search --no-floppy --fs-uuid --set 76fe9a67-1168-4154-b994-4b466e92f7df
and
linux /boot/vmlinuz-2.6.32-15-generic
root=UUID=76fe9a67-1168-4154-b994-4b466e92f7df ro
