How to Edit GRUB on Ubuntu

GRUB is the graphical boot loader used in several Linux distributions that lets you select what operating system to start when you turn on your computer. You can edit the parameters of the GRUB boot loader through a Linux text editor. Use extreme caution when performing this task, as improper modification of the GRUB boot loader can cause the boot to fail.

Instructions

1. Log in to your Ubuntu computer.

2. Open the System menu, then open a Terminal window.

3. Type "vim /etc/grub.conf" into the terminal window and press "Enter."

4. Make the desired changes to the GRUB configuration file, then press "Esc." Type "ZZ" and press "Enter" to save the changes and exit the VIM text editor.

5. Restart the computer to apply and view the changes to GRUB.
