Repair HFS+ when your BootCamp is error
Restart your Mac. As soon as it turns on, even before you hear it go bong, hold down Cmd+S. The system will boot showing a lot of text. If it doesn't and you see the Apple logo, you've waited too long. Reboot and try again. When at the prompt type fsck -f . If changes are successfully made it will repeat the process then say "Modifications have been made". Then simply type in reboot and you should be able to partition your drive successfully. http://hints.macworld.com/article.php?story=20080120064811786
