美国买笔记本给父母用，英文版得换成中文版。但一般情况下，win 7只允许ultimate版免费安装语言包进行切换。
因为不想浪费正版序列号，网上搜了下如何添加中文包，找到这么一篇

简单的讲就是下载这个软件，Vistalizator 和微软官方的语言包 （在网站上有link，注意下载x86还是x64的，和你系统对应）
然后用这个软件添加。
如果是sp1的朋友，这个软件会出现错误，说不支持你的版本7601。
只需要用兼容模式运行即可（看文件属性，选择run as ~windows 7~)
添加时如果遇上不成功，试试fast 模式。

Lion is not designed to be installed standalone. You could only upgrade from Snow Leopard.
My system was also upgraded from Snow Leopard; but the system became really slow after upgrading. So I decided to perform a clean installation. But I don’t want to re-install Snow Leopard and then upgrade.
After research, I found it not that hard to install Lion directly.
First you need a 8Gb flash drive or SD card. (I used SD card.)
Make a bootable drive from the DMG file you have. Please refer to

Reboot your system and hold option key. Boot from your flash drive.
Use Disk Utility to erase your HD.
Install Lion.
That’s it!
Enjoy your clean Lion.
