Answer 1

You can not delete or remove grub as grub is responsible for booting.

You can, however, configure grub to hide the menu.

Edit /etc/default/grub

# Graphical 
gksu gedit /etc/default/grub

# command line
sudo -e /etc/default/grub

And edit or add these lines

GRUB_HIDDEN_TIMEOUT=1
GRUB_HIDDEN_TIMEOUT_QUIET=true

GRUB_HIDDEN_TIMEOUT=X

X is a positive integer (e.g. 1, 5, 10, etc)

The boot process will pause and display a blank screen or the designated splash >image for X seconds. At the end of the time period, the system will boot. No menu will >be displayed. While GRUB_HIDDEN_TIMEOUT is active, the menu can be displayed by pressing any >key.

See: https://help.ubuntu.com/community/Grub2#Hidden

In terms of old kernels, remove them. either from the command line of software center.

Is there a way to remove/hide old kernel versions?
