You shouldn't use NBBM to fix that problem though. Instead, you must use NBI to install the Chameleon boot loader. From Chameleon, you will probably get an error when you try to boot into Windows 7. You fix that by following the instructions for using your Win 7 flash drive or installation CD to repair the boot sector, as detailed here
or in mechdrew's guide. Three tips for this fix: one, I have found that sometimes the Win 7 repair function doesn't work the first time, so be sure to test your ability to boot into Windows afterwards and try the repair again if you can't. Two, sometimes the repair function replaces the "boot\BCD" file on your Win 7 installer flash drive with a file that causes subsequent repair attempts to report an error. Just rename "BCD.backup" to "BCD" to make repair work again. I made the "BCD" file read only and that seems to help prevent this issue. Three, sometimes the Windows 7 "diskpart" tool will report that it cannot set a partition active on a non-MBR drive. Running "gptsync" from OS X will fix this by re-syncrhonizing the hybrid GUID/MBR partition table.
