Ubuntu – After Dual Ubuntu Installation the boot screen doesn’t updated


Today I tried to install lubuntu13.10 on ubuntu10.04 by creating a separate partition(/dev/sda3).

But after installation the boot screen doesn't updated. ie it only shows ubuntu10.04…

While installing lubuntu13.10 I changed default boot path from /dev/sda1 to /dev/sda3.

Is that the problem? How to fix it??

Update 1:

when run gparted i got:

Update 2:

when i run sudo update-grub:

debconf: unable to initialize frontend: Dialog
debconf: (Dialog frontend requires a screen at least 13 
  lines tall and 31 columns wide.)
debconf: falling back to frontend: Readline
