====/boot/grub/menu.lst==== menu.lst - See: grub(8), info grub, update-grub(8) grub-install(8), grub-floppy(8), grub-md5-crypt, /usr/share/doc/grub and /usr/share/doc/grub-doc/. default num Set the default entry to the entry number NUM. Numbering starts from 0, and the entry number 0 is the default if the command is not used. You can specify 39;saved39; instead of a number. In this case, the default entry is the entry saved with the command 39;savedefault39;.
