I assume we are clear that you are using the Ubuntu grub not the Fedora
grub. What you show as grub.cfg I assume corresponds to Fedora
grub.conf. In Fedora the grub.conf has a line:
boot=/dev/sda
does Ubuntu grub.cfg have an equivalent line. The syntax of your
grub.cfg is so different than grub.conf it is  difficult to match
functionality.
