how do I delete grub on Ubuntu 11.10. I want to get into ubuntu normally without having to choose which operating system I would run. and how to remove ubuntu with older kernels as shown below
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.
How do I remove old kernel versions to clean up the boot menu?
