装了双系统 主要用UBuntu
XP只是玩游戏，用的不多
开机是会显示U和XP的多系统选项
能否设置成开机默认进U ，只有在开机时按ESC才进入多系统选择？

已解决
其实只要加上hidemenu这一句就可以做到（默认的是＃注释）
如果Timeout是10的话会等10秒
我把Timeout改为0 基本可以直接进去 而且绝对够时间按ESC进入多系统选择菜单

time=1也不行

那界面这么不待见

那描述也可以改的，就改一个X一个Y呗

hcym 写了：time=1也不行

楼上能否说具体一点？
我是菜鸟

我这个改怎么改呢？

刚才试了一下 貌似改的不对

default 0
这一行改为
default 1

fscyr 写了：default 0
这一行改为
default 1

改成1 默认的启动变成XP 选项还是在的

改成 这都加注释隐掉，那天回过味了再改 default 0
这一行 不动

hcym 写了：

代码： 全选

title Ubuntu 8.04 Kernel 2.6.24-18 Generic

改成

代码： 全选

title U

这都加注释隐掉，那天回过味了再改

代码： 全选

default 0
这一行 不动

照你这样改的话是不是 即使启动时按ESC也进不了XP 除非进了U再改回来？

这到是，呵呵，不对路子

你再找找，刚刚看到一帖说这

好像以前7.1是有开机菜单显示
升级到8.04之后，就只有按Esc进入菜单的提示了。

这个，我是直接把 win的菜单注释掉，这样启动的时候就没有win的菜单可以选择了，然后开机想要进win了，就编辑某个启动菜单，把root那里改下，再把下面两行删掉改成makeactive和chainloader +1再按b启动，很麻烦，但是这样别人就不能乱动我的电脑了。
