谢谢指教！！

# Set the default entry to the entry number NUM. Numbering starts from 0, and

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).

## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
#hiddenmenu

我把timeout直接设成0，默认启动应该是u吧！！那这个hiddenmenu怎么应用？？？

[注册太麻烦]

就是把这几行都注释了

＃hidemenu 去掉＃

楼上的方法可行，但是麻烦。
其实可以这样做：
如果你是grub，编辑 /boot/grub/menu.lst,添加一行字符 hiddenmenu就好了
如果是grub2，编辑同样目录下的grub.cfg，同样添加上述一行

最好把timeout设置短点比如 timeout 5
这样等待5秒就启动了首选的系统

如果要启动其他os，比如windows，那么，趁这5秒(timeout 5)没过，按下 esc 键就可以调出列表的

[Kandu]

看了楼主的menu.lst
把第13行的timeout改改小点
把第17行的#hidemenu那行开头的#去掉
就可以搞定啦

把timeout设置成0的话，就和把其他列表都注释掉一样，麻烦。
