Ubuntu 12.10 features a minor but interesting change in GRUB2 Boot Menu.
Menu entries now have 'Ubuntu' as the first option instead of 'Ubuntu with Linux (Kernel version)'. Everything else has been tucked into a new 'Advanced Options' entry which lists older Kernels and recovery mode options.
Here is a screenshot of new boot menu:
For comparison, here is a screenshot of boot menu in Ubuntu 12.04:
New boot menu makes sense as any first time Linux user may get confused by recovery mode option and Kernel versions. A simple 'Ubuntu' entry is enough to tell a user what to do in case he is presented with a boot menu.
By default GRUB menu is hidden and it is only shown when a system fails to shut properly or Shift key is held during boot time.
