To aluminumapple:
This is directed to the OP, not to others who may or may not have the same issue (accidentally formatted using Windows installer).
There should have been a warning in the screen of the Windows installer that you were formatting the 132GB partition. I have never been able to accidentally format a partition using either Windows or OS X installer disc, but I suppose there could be a first time.
Now that the water is under the bridge, you have to partition the entire drive using Disk Utility while booted to the OS X install DVD. In OS 10.5.8 and older, open Disk Utility from the "Utilities" menu at top. For OS 10.6, click the "Utilities" button at the bottom. You will choose the "Partition" tab, choose "1 partition", and click the "Options" button. Choose "GUID" partition scheme for any Intel Mac like yours. Click to partition. Wait. When it is done, be sure the format is "Mac OS Extended (journaled)" and not anything else, not even "Case Sensitive". If it is not correct, choose the "Erase" tab and erase as "Mac OS Extended (journaled)". When that is done, quit Disk Utility, and do the OS X installation.
Technically, you could have created two partitions when you applied the GUID. I have done that and later booted to Windows install disc and installed. Everything went fine without using Boot Camp Assistant at all.
After OS X is installed and it reboots to let you do the account setup, finish that and open Boot Camp Assistant if you did one partition, and use the option of the BCA to make a second partition.
When that is done, boot to the Windows install disc (facilitate this by either setting the Windows DVD/CD as the Startup Disk in System Preferences, or by holding the alt/option key for 30 seconds during restart). Wait a long time for Windows to copy its temp files, and you should get the option of choosing where to install Windows. Choose the FAT-32 or whatever partition (careful, now). Format as NTFS if you don't mind having to deal with installing MacFuse and NTFS-3G to enable writing to the Windows partition while using OS X. Me, I would never use FAT-32 as it is really ancient technology that even Microsoft shrinks away from now, and it cannot use any file larger than 4GB -- no large videos. After the format (I ALWAYS use the normal format method, never the "quick", just to be sure -- worth the extra time), install Windows. When that is done, restarts, and does all the additional agonizing stuff, put the OS X DVD in and wait. The "Boot Camp" driver install will launch after five-ten seconds and off you go.
