ubuntu 9.10 启动菜单

最近升级了新鲜出炉的ubuntu 9.10。发现启动菜单配置文本 /boot/grub/menu.lst 不见了。取而代之的是/boot/grub/grub.cfg，grub2不再使用menu.lst。

 

grub.cfg是个只读文件，首先要去掉只读：

sudo chmod 744 /boot/grub/grub.cfg

 

使用sudo gedit /boot/grub/grub.cfg 编辑配置：

 

### BEGIN /etc/grub.d/00_header ###
if [ -s /boot/grub/grubenv ]; then
  have_grubenv=true
  load_env
fi
set default="1"
if [ ${prev_saved_entry} ]; then
  saved_entry=${prev_saved_entry}
  save_env saved_entry
  prev_saved_entry=
  save_env prev_saved_entry
fi
insmod ext2
set root=(hd0,8)
search --no-floppy --fs-uuid --set b9c8f0c6-f9c5-4eba-bdbb-db509bdea0bf
if loadfont /usr/share/grub/unicode.pf2 ; then
  set gfxmode=640x480
  insmod gfxterm
  insmod vbe
  if terminal_output gfxterm ; then true ; else
    # For backward compatibility with versions of terminal.mod that don't
    # understand terminal_output
    terminal gfxterm
  fi
fi
if [ ${recordfail} = 1 ]; then
  set timeout=-1
else
  set timeout=10
fi
### END /etc/grub.d/00_header ###

### BEGIN /etc/grub.d/05_debian_theme ###
set menu_color_normal=white/black
set menu_color_highlight=black/white
### END /etc/grub.d/05_debian_theme ###

### BEGIN /etc/grub.d/10_linux ###
menuentry "Ubuntu, Linux 2.6.31-14-generic" {
        recordfail=1
        if [ -n ${have_grubenv} ]; then save_env recordfail; fi
    set quiet=1
    insmod ext2
    set root=(hd0,8)
    search --no-floppy --fs-uuid --set b9c8f0c6-f9c5-4eba-bdbb-db509bdea0bf
    linux    /boot/vmlinuz-2.6.31-14-generic root=UUID=b9c8f0c6-f9c5-4eba-bdbb-db509bdea0bf ro   quiet splash
    initrd    /boot/initrd.img-2.6.31-14-generic
}

### END /etc/grub.d/10_linux ###


### BEGIN /etc/grub.d/30_os-prober ###
menuentry "Microsoft Windows XP Professional (on /dev/sda1)" {
    insmod ntfs
    set root=(hd0,1)
    search --no-floppy --fs-uuid --set 3ac4bcbbc4bc7aa9
    drivemap -s (hd0) ${root}
    chainloader +1
}
### END /etc/grub.d/30_os-prober ###
