Macbook Pro hangs when booting into Boot Camp Windows 7
If you get a copy of Paragon NTFS for Mac you can do a disk repair for NTFS volumes. The software has a 10 day trial and a license is about $20. NTFS for Mac also serves as a driver for full access to NTFS volumes which is superior to the limited Read only access of NTFS volumes built into Macs. If you are a regular user of both Mac and Windows its worth the investment. 

Once installed the program is accessible from System Preferences. For the problem described above you need to first unmount the volumes "System Reserve" and "BootCamp". Then remount the volumes and run verify on each volume.
