更改Ubuntu 10.04和Windows 7启动顺序

刚安装了双系统，分别是windows7（先）和Ubuntu10.04（后）（非wubi安装）,. 默认是Linux启动,通过下面的操作可把windows7改为默认启动系统
启动ubuntu后，在终端中输入：先备份 sudo cp /boot/grub/grub.cfg /boot/grub/grub.cfg.backup
修改启动列表：sudo gedit /boot/grub/grub.cfg（注意不是sudo gedit /boot/grub/menu.lst,貌似9.10就改为了grub.cfg）
然后找到
default 0
然后往下看，找你想默认启动的操作系统！修改default 后面的数字，0对应第一个，1对应第二个，依次往下！以下是我的grub.cfg
默认是ubuntu！把0改为4就可以了！（升级内核之后数字酌情修改）#

上面的自己修改default后面的数字。！··如果你觉得这样不方便到话，我建议你把win7的那一项剪切到ubuntu前面也就是这个样子，这样既美观又方便（不用修改default后面的数字）。#
