联想win8更改win7 XP系统

联想win8更改win7 XP系统 知识点分析: 目前联想出厂预装Windows 8的台式和一体机使用都是UEFI+GPT硬盘的组合，并且开启了安全启动，但是目前除Window 8以外的其他Windows系统均不支持这种模式，因此如果需要改装其他系统，如Widndows 7，必须工作在传统的BIOS+MBR模式下。 如果不修改任何设置，则无法正常从光盘引导安装其他操作系统。 如下内容为出厂预装Windows 8改装Windows 7的具体操作步骤。 特别提醒: 1、此操作会导致硬盘所有数据清空，包括一键恢复功能也会被清除,如果需要恢复windows8系统和一键恢复功能,您需要送到服务站操作,1年内免费。(GPT硬盘转换为MBR硬盘时需要删除原来的所有分区) 2、安装Windows 7等操作系统时必须使用正版的安装光盘，这样在删除分区重新创建时，安装程序会自动把GPT转换成MBR,请勿使用ghost光盘或第三方分区工具重新划分分区，否则可能导致系统无法正常安装或不能正常引导等不可预知的情况 3、如果硬盘中存有数据，您必须备份整个硬盘的数据，而不仅仅是C盘的数据(原因见第一条) 支持机型: 此文档仅适用于联想出厂预装Windows 8的消费台式机电脑和一体机电脑 IdeaCentre B540/IdeaCentre B545/IdeaCentre B540P//IdeaCentre B340/ Lenovo C340/Lenovo C445 /Lenovo C345/Lenovo C440/Lenovo C540/ IdeaCentre A720 / IdeaCentre K415/ IdeaCentre K410 / 新圆梦F2999/新圆梦F4039/新圆梦F415/新圆梦H505/新圆梦F3152/新圆梦H520/ 家悦s520/家悦S525 / Lenovo H430 / Lenovo H415 /等等。 操作步骤: 一、BIOS设置(不同机型BIOS界面可能有细微区别，请以实际机型为准) 1. 启动时不断点击键盘上的F1键,进入BIOS 界面， 按键盘上的右方向键(?)选择到“Exit” 按键盘上的下方向键(?)选择到 “OS Optimized Default”， 按键盘上的上方向键(?) 选择到“Disabled”。 按键盘上的回车键(Enter)，更改设置。 (OS Optimized Default 选项可以理解为UEFI和传统BIOS的切换); stator.
