呵呵，这个问题是很简单的，只要你不要一键恢复，那么右键单击我的电脑，单击管理，单击磁盘管理，鼠标放在要删除的分区上单击右键，会出现窗口，有选项为:删除磁盘分区，或格式化分区的选项，操作就可以了。但是要想在我的电脑窗口显示未分区或把容量增加到其他分区，那就把他的前一个分区中的内容全部拷贝出来，然后在右键中你自己应该能操作的。祝你成功。
没那么麻烦 OEM分区其实主要是放置联想的随机软件的 如：联想一键拯救系统 如果需要破坏的话 买一张GHOST版本的XP系统 进入PE里面 重新做一次系统就OK 步骤选择113 单做C盘是123
看不到硬盘分区是正常的 你要重新启动电脑 然后按F1进入BIOS里面 右边第2个选项里面有个选项可以更改 IDE接口跟AHIC接口的那个 改成IDE就OK乐 然后在PE下面就会有分区了
打开CMD，输入 diskpart.exe 回车
然后输入 rescan 回车
接着输入 list disk 回车 （可以看到连接到该主机的硬盘列表，一般只有一个硬盘）
select disk 磁盘号 回车 （选择一个磁盘）
list partition 回车 （显示磁盘中的分区）
select partition 分区号 回车 （选择一个分区，注意选择OEM分区，看分区的大小就能判断出）
delete partition override 回车 （删除OEM分区）
就能删除OEM分区了。
可以通过进入bios，通过PE进行格式化OEM分区。进入bios步骤如下：
1..打开电源，然后观察屏幕的提示，在启动系统之前有按“F2进行BIOS设置。
2.设置启动方式。这个设置画面就是BIOS设置。找到boot的选项，有第一启动，用英文表示的，一般是1st Boot Device（第一启动设备），后面有一个选项，用光标移动到上面，按回车键进去选择带usb字样的那一项，按回车键确认。光标移动的按键方法有的是键盘的方向键，有的是F5和F6，这个看屏幕的提示。然后按F10，选择yes，按回车键确定，就将U盘启动设置为第一启动项了。
3.然后就能进入pe，格式化分区。
您好，您可以使用系统光盘在安装界面直接删除隐藏分区，但是如果删除后再需要恢复就要送到服务站进行恢复了。
