一、准备工作:
1.准备好Windows XP Professional 简体中文版安装光盘,并检查光驱是否支持自启动。
2.可能的情况下，在运行安装程序前用磁盘扫描程序扫描所有硬盘检查硬盘错误并进行修复，否则安装程序运行时如检查到有硬盘错误即会很麻烦。
3.用纸张记录安装文件的产品密匙(现在很多安装盘都是免输入的)。
4.可能的情况下，用驱动程序备份工具(如:驱动精灵 2004 V1.9 Beta.exe)将原Windows XP下的所有驱动程序备份到硬盘上(如∶F:\Drive)。最好能记下主板、网卡、显卡等主要硬件的型号及生产厂家，预先下载驱动程序备用。
5.如果你想在安装过程中格式化C盘或D盘(建议安装过程中格式化C盘)，请备份C盘或D盘有用的数据。
二、用光盘启动系统:
重新启动系统并把光驱设为第一启动盘(开机时按下DEL键进入BIOS设置,再进入ADVANCED BIOS FEATURES,把FIRST BOOT DEVICE设为CDROM,按F10后回车重启)。将XP安装光盘放入光驱,重新启动电脑。刚启动时，当出现如下图所示时快速按下回车键，否则不能启动XP系统光盘安装。

三、安装Windows XP Professional
光盘自启动后,如无意外即可见到安装界面 ,将出现如下图所示

全中文提示,“要现在安装Windows XP,请按ENTER”，按回车键后,出现如下图2所示
[img]http://img005.photo.wangyou.com/2005/8/22/140718/200511326681532_s.jpg[/img]
按“F8”后如下图3
[img]http://img005.photo.wangyou.com/2005/8/22/140718/200511326681533_s.jpg[/img]
这里用“向下或向上”方向键选择安装系统所用的分区，请选择C分区，选择好分区后按“Enter”键回车，出现下图4所示
[img]http://img005.photo.wangyou.com/2005/8/22/140718/200511326681534_s.jpg[/img]
这里对所选分区可以进行格式化,从而转换文件系统格,或保存现有文件系统,有多种选择的余地,但要注意的是NTFS格式可节约磁盘空间提高安全性和减小磁盘碎片但同时存在很多问题.98/Me下看不到NTFS格式的分区,我们在这里选“用FAT文件系统格式化磁盘分区(快),按“Enter”键回车，出现下图5所示(当然你也可以选用NTFS分区格式)
[img]http://img005.photo.wangyou.com/2005/8/22/140718/200511326681535_s.jpg[/img]
格式化C盘的警告,按F键将准备格式化c盘,出现下图6所示

在这里可能你要多等上一会儿了,根椐机子配置不同它会停留在39分钟上相当长一段时间约3分钟
然后才有了反应
你除了等待还要做的就是一路根据提示输入你自己的信息并点击"下一步"
如以下图.....

到这里后就不用你参与了，安装程序会自动完成全过程。安装完成后自动重新启动，出现启动画面，如下图
[img]http://img005.photo.wangyou.com/2005/8/22/140718/200511326689528_s.jpg[/img]
第一次启动需要较长时间，请耐心等候，接下来是欢迎使用画面，提示设置系统，如下图
[img]http://img005.photo.wangyou.com/2005/8/22/140718/200511326689529_s.jpg[/img]
点击右下角的“下一步”按钮，出现设置上网连接画面，如下图所示
[img]http://img005.photo.wangyou.com/2005/8/22/140718/200511326694180_s.jpg[/img]
这里我们不急着安装上网的事儿,先装完系统再设也不迟啊.于是我们点击"跳过"进入下图
[img]http://img005.photo.wangyou.com/2005/8/22/140718/200511326694181_s.jpg[/img]
随便输入一个就够了,装完再改名字也行.接着下一步就有了激动人心的了!
[img]http://img005.photo.wangyou.com/2005/8/22/140718/200511326694182_s.jpg[/img]
在这之后我们终于看到安装系统成功了!!!

阿弥陀佛..安装硬件驱动去吧.我的任务完成了!
从新分区，这样你硬盘上的东西就会全部被删除，像新买的一样（电脑上什么东西都没有），重新安装系统之后可以安装什么软件就看你要拿电脑干什么用，平常就需要几个常用的软件，比如winrar、迅雷或网际快车、暴风影音或real play等等，必不可少的就是驱动了，那是必须装的。想让电脑启动和进入程序的速度快一些，推荐你装XP总管，优化一下。
格式化整个硬盘，然后分区。装好以后建议装Microsoft Office 2003,Photoshop 9.0或ACDSee 8.0 Phot Manager,QQ,暴风影音5.07，BitComet 0.60，迅雷5.0，WinRAR 3.51，至于杀毒软件还是KV2006的好，再配上防火墙好了！
首先把硬盘从机箱里拿出来！！然后拆开用布擦干净！再把windows XP光盘一块装进去就！再装上硬盘就好了！！嘻嘻！！开玩笑的！！不要真的这样做哦！！！````
用优化大师好一些，自己设置一下就可以了，很方便的！！
