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
