You buy a Windows 7 DVD. Open Boot Camp Assistant (in /Applications /Utilities). Use it to make a partition for Windows install. It shows half the HDD for Windows as a default setting, but you can slide the bar to what you like. The minimum space needed for a fresh install of OS 10.6 and all its updates (now or later) is about 20 GB. The minimum for 7 with updates is about 15 GB. At the end of making the partition, a message says to put in the Windows DVD, and click the "Restart" button. It should boot to the 7 DVD, but if boots to OS X, restart holding the option key and choose the 7 DVD. Stay put and wait for the idiotic "To boot from the DVD, press any key" message, because the 7 DVD will un-mount after a few seconds, leaving you to restart again. Grrr!!! Windows doesn't expand on-the-fly and install right away like other OSes, so you wait a couple of minutes for it to copy the archives to the HDD, and expand them. Then you choose to do a fresh install of 7, select the Windows partition (may be shown as "unallocated space" or whatever), click to format it, wait, install. After the install finishes-- oops, make that after half the install finishes, it restarts and you finish the install-- and then it really works. Put the OS X DVD in and wait a few seconds. Click the "protection" message to allow opening "Setup" and install the BootCamp setup (drivers and two control panels).
My method is to install NTFS-3G in OS X to have read-write of the NTFS partition, and then in the Boot Camp Assistant, make the 7 partition all the HDD space except 20 GB. You need NTFS-3G because the Apple NTFS driver is read-only. The result is your being able to save documents to, rename documents on, and move documents around on the large partition while using either OS X or 7. You can set the preferences of iTunes in both OS X and 7 to use the same music folder, iPhoto to use a photos folder on the NTFS partition, Safari or Firefox to download to a "Downloads" folder on the NTFS partition --- and so on. You don't want to keep two sets of music files or two sets of movies just because 7 can't deal with the OS X partition.
