Ubuntu – Cannot find GRUB configuration file

configurationgrub2

I have been looking for the GRUB configuration file, and I haven't had much luck. According to the sites I found, it should be at '/boot/grub/menu.lst'. But, I went to that file path, and could not find menu.lst. Can anyone tell me why it isn't there, and where I might locate it? I would like to change the default system to boot, but I cannot find any related files to help me.

Recent releases of Ubuntu have migrated to GRUB2. From the wiki:

Configuring GRUB 2

Important note: Configuration changes are normally made to /etc/default/grub and to the custom files located in /etc/grub.d. The /boot/grub/grub.cfg file should not be edited by the user; changes to this file are made by configuration scripts. After editing /etc/default/grub, you need to run sudo update-grub for your changes to take effect on the next boot.
