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Ubuntu 10.04(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)
