使用bcdedit 更改windows vista 的启动顺序

Posted by abloz on October 10, 2006

下了个windows vista试用,等我旅游一趟回来,发现要激活。但我又没有激活码,所以连操作系统都进不去。vista安装后更改了启动顺序,将vista 设为缺省启动。这样我每次启动电脑一不留神就跑vista里面去了,而又不能用。查看XP的boot顺序,根本连vista的选项都没有。这就是说,我无法更改启动顺序,而缺省却总引导到一个我不能用的vista?

查看XP的boot.ini,发现vista加了个注释:

; ;Warning: Boot.ini is used on Windows XP and earlier operating systems. ;Warning: Use BCDEDIT.exe to modify Windows Vista boot options. ;

因此找到装vista的E盘的windows/system32目录,

使用bcdedit.exe来更改启动选项。

该程序是字符界面。选项很多。经过摸索,成功更改了启动顺序,并删除vista的启动选项,手工将vista直接从硬盘中清除。

1.在cmd模式下,切换到 e:windowssystem32,执行bcdedit /v命令

E:WindowsSystem32>bcdedit /v

看到了Windows Legacy OS Loader的identifier 为 {466f5a88-0af2-4f76-9038-095b170dc21c}

2.执行下面的命令,将缺省启动选项改为XP:

E:WindowsSystem32>bcdedit /default {466f5a88-0af2-4f76-9038-095b170dc21c} 操作成功完成。

查看一下启动选项:

E:WindowsSystem32>bcdedit

nx                      OptIn

3.更改timeout时间

E:WindowsSystem32>bcdedit /timeout 0 操作成功完成。

4.将Vista的选项清除

E:WindowsSystem32>bcdedit /delete {77c363ea-4851-11db-9098-ba68b5106fc5} 操作成功完成。

然后就可以将E盘的Vista直接删除了。最好是格式化。
