Default Why am I getting error BC9 when trying to install Windows 7 SP1

Here is the situation:
I have multiple operating systems on a custom built PC. Mac OS X 10.6.7 and Windows 7, both 64 bit. I tried installing Windows 7 SP1 and I was getting an error so I researched it and found out that it wasn't installing correctly because the Mac bootloader (Chameleon) was stopping it. So I changed the default boot partition to Windows 7 and attempted to reinstall SP1. The installation went smoothly until I had to restart. What I should have done was restarted the computer, then set Chameleon to the default boot partition, but I set it as default before I restarted. When W7 started back up, it said the normal "Windows is configuring updates X%" and got to 99% then said, an error had occurred and it was reverting all settings. Now every time I try to install it, whether it be through Windows Update or the standalone installer, it says "The Windows Service Pack Installation cannot proceed until your computer is restarted. Please restart your computer and try again." No matter how many times I restart the computer and no matter what bootloader I use, I get this message. I was thinking of doing a fresh install, then copying the contents of the Windows.old folder to my new install and just choosing to not overwrite any files (it would copy my programs, pictures, music, etc.). Would that work? Is there anything less drastic that I can do? Any help would be greatly appreciated.

Thanks in advance,
Coby Finger
