I can't boot into Windows 7 on Boot Camp
I'm very excited that to say that booting Windows fixed itself. My machine: MBP 2010. OSX Fuse installed. Recent update on one OSX partition to Mavericks.

My machine automatically ran its CHKDSK function and restored its own ability to boot. It found orphaned files and repaired the links. If you can figure out how to force CHKDSK to start you may find everything fixed. Best of luck!
