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:
