Grub2 is a verry different beast, a custom boot menu can be generated 
with /etc/grub.d/40_custom

As a root user, to change the default boot item change

Be carefull to count from the top starting with 0 for the first line, if 
there is a recovery mode this counts as one more item too.

GRUB_DEFAULT=0 to the correct value in /etc/default/grub

then run 

update-grub2
