x86: Modifying Boot Behavior by Editing the GRUB Menu at Boot Time

The following is an example of a GRUB main menu in a Solaris release that supports booting a system from a ZFS root file system. This menu is based on the contents of the menu.lst configuration file and includes menu entries for all of the bootable OS instances on the system. The first entry in the menu is the default, unless otherwise specified. To specify another boot entry as the default, add the default=n command to the menu.lst file, where n is a number, starting from 0 (the first boot entry).

      Use the ^ and v keys to select which entry is highlighted.
      Press enter to boot the selected OS, 'e' to edit the
      commands before booting, or 'c' for a command-line.
Note –

The information that is contained in the menu.lst file varies, depending on the Solaris release and the installation method that was used.

To edit a boot entry in the GRUB menu, use the arrow keys to select the entry, then type e.
