Grub Managment

  • In your Ubuntu open a terminal (press Ctrl+Alt+T at the same time)
  • Type gksu gedit /etc/default/grub
    This will run text-editor gedit, if you're using another one just type the name of it instead of gedit.
  • Make the changes you would like to make and save them.
  • Close gedit.
    Your terminal should still be open.
  • In the terminal type sudo update-grub, wait for the update to finish.
  • Reboot your computer.
  • Open a terminal again (Ctrl+Alt+T).
  • Type in the terminal gksu gedit /etc/default/grub
  • To see the grub-menu at boot time,
    comment or remove the following line: GRUB_HIDDEN_TIMEOUT=0
    • To comment, add # at the beginning of this line, the result will be #GRUB_HIDDEN_TIMEOUT=0
  • Save the file.
  • Again in the terminal run sudo update-grub.
