Above links introduce the installation in detail, except after the installation, you should insert Mac DVD in windows environment to install the drivers using boot camp. After installation, there should be a software named as "boot camp" in windows, and you can use it to interact with mac.
However, above method doesn't work this time. May be the installation DVD is for snow leopard but the iMac is lion. After the installation as the above method, system cannot detect my network hardware, which proves that the failure of the installation. My solution is go back to mac system, and use "Boot Camp Assistant", and choose "Download the Windows support software for this Mac". It will download the exact drivers of the hardware used on this iMac for windows. I stored it in a USB disk and then install it on Windows. This time it works perfectly. Not only the wireless network, but the wireless keyboard.

To choose the default OS when logging in, there are two ways. If you are in mac OS, in Mac->System Preference->Startup Disk->Choose MacOS. If you are in Windows, you can use "boot camp" software and choose the default login system. When you want to use switch occasionally, just pressing "Option" key before OS starts. It will let you choose the system you like.
