Grub 2

I just realized that the newer Ubuntu versions use Grub 2 instead of the older Grub. And in Grub 2, there are some significant changes (see here):

• Scripting support including conditional statements and functions
• Dynamic module loading
• Rescue mode
• Custom Menus
• Themes
• Graphical boot menu support and improved splash capability
• Boot LiveCD ISO images directly from hard drive
• New configuration file structure
• Non-x86 platform support (such as PowerPC)
• Universal support for UUIDs (not just Ubuntu)

Note to self:

1. /boot/grub/menu.lst no longer exists, and this has been replaced by /boot/grub/grub.cfg and /boot/default/grub.
2. To edit the display settings, edit /etc/default/grub, and then run sudo update-grub, which will generate /boot/grub/grub.cfg
