Q: Bootcamp Problems after Yosemite Update

Hello, community.  As many before me quite recently, I've been having troubles with my win 7 bootcamp partition after updating to yosemite.  Having gone through many methods online going into making the partition workable again, I've found Loner T's methods the only ones that seem to work.

I've followed most of the necessary steps I've garnered from a bunch of the other threads here, and have installed Parted Magic unto a bootable USB and with testdisk found a sector that seems to identically match my sudo fdisk /dev/disk0 output that I get in OS X:

Disk: /dev/disk0    geometry: 30515/255/63 [490234752 sectors]

Signature: 0xAA55

         Starting       Ending

#: id  cyl  hd sec -  cyl  hd sec [     start -       size]

------------------------------------------------------------------------

1: EE    0   0   1 - 1023 254  63 [         1 -     409639] <Unknown ID>

*2: AF 1023 254  63 - 1023 254  63 [    409640 -  400650744] HFS+       

3: AF 1023 254  63 - 1023 254  63 [ 401060384 -    1269536] HFS+       

4: DA 1023 254  63 - 1023 254  63 [ 412110848 -   78123008] <Unknown ID>

In Parted Magic, after choose EFI/GPT, analyze, and quick search, I get,

Disk /dev/disk0 - 251 GB / 233 GiB - 490234752 sectors (RO)

Structure: Ok.  Use Up/Down Arrow keys to select partition.

Use Left/Right Arrow keys to CHANGE partition characteristics:

                P=Primary  D=Deleted

Keys A: add partition, L: load backup, T: change type, P: list files,

     Enter: to continue

NTFS found using backup sector, blocksize=4096, 39 GB / 37 GiB

The MS Data on the bottom's start and size matches the one I've found earlier.  So what do I do from now?  I could not make out fully what to do at this point in the process, and would like further advising.  Currently I am deep searching the MS Data partition.  Thanks to all who respond beforehand (especially Loner T)!!
