Bootcamp disk0s4 after Yosemite update (fdisk and testdisk info)

Question

Hello everyone and Loner T,
I've been following the threads where similar issues were reported. I downloaded Testdisk and GPT disk. And I've been trying to follow the directions as best I could on my own to provide you with the information needed for support. I have a 40 GB Windows 7 Bootcamp partition on a 200 GB Macbook Pro Early 2008 HDD. Before the Yosemite upgrade, I have successfully added another 10 GB to the windows partition by shrinking the Mac OS partition. After the upgrade, the bootcamp was not visible as a bootable partition to be selected after restart and displayed as disk0s4 in Disk Utility. In addition, the 10 GB are now displayed as unallocated space. I have since downgraded to Mavericks 10.9.5 since Yosemite keeps on lagging on my maschine. I hope you can help me too recover the data stuck under Windows. Thank you for your kind assistance.

2.     I have followed the instructions in Bootcamp win8.1 autorepair fail after yosemite upgrade post to perform a deep search in Testdisk.
After analyzing the EFI GPT partition map, Testdisk returns:
Disk /dev/disk0 - 200 GB / 186 GiB - 390721968 sectors (RO)
Current partition structure:
     Partition                  Start        End    Size in sectors

3 P Mac Boot               291796352  293065887    1269536 [Recovery HD]

4 P MS Data                312598528  390721535   78123008 [BOOTCAMP]
QuickSearch returns:
Disk /dev/disk0 - 200 GB / 186 GiB - 390721968 sectors (RO)
The harddisk (200 GB / 186 GiB) seems too small! (< 250 GB / 232 GiB)
Check the harddisk size: HD jumpers settings, BIOS detection...
The following partitions can't be recovered:

Answer 1

The first entry you posted is the correct one. Glad to see you found it. I have this table to make sure no existing partitions are lost.
GPT 3 Start
GPT 3 Size
GPT 3 End
NTFS Start
Sector Offset
NTFS Size
NTFS End
291796352
1269536
293065888
293066752
864
97654777
390721528
The 'Sector Offset' being positive is good. A negative value means you lose GPT#3. The NTFS size is roughly 48GB which is good.
You need to use the following steps. If you see any error messages during the following steps, please stop and post back here with the error message. The following steps have values from your Testdisk output (and you can verify) in Steps 7 and 8.
Rebuild GPT4 using start/end offsets
Sudo gdisk /dev/rdisk0
P  (print the full list of parts)
D  (delete)
4  (part 4)
N  (new part)
4   (part 4)
293066752 - Start offset in bytes  (start point for Bootcamp part)
[phone] (Size offset as opposed to End offset)
0700     (Windows part type)
P           (print list of all parts just to see what changes will be made)
W         (Write the new GPT)
Y           (Yes! really write the new GPT)
  This will delete and re-write the GPT partition info for /dev/disk0s4. 
Rebuild MBR to match the new GPT information thus resetting the Hybrid MBR. Use defaults for other questions (like partition codes).
Sudo gdisk /dev/disk0
P  (Print list of parts)
R   (Recover)
H (chooses Hybrid)
Partitions numbers to be hybridized: 2 3 4
Y (Good for GRUB question)
N (part 2 boot flag)
N (part 3 boot flag)
Y  (part 4 boot flag make NTFS bootable partition)
W  (Write the new MBR)
Y    (Yes! write the new MBR)
Reboot
Test 1 - Does Bootcamp Volume show up in Finder?
Test 2 - Can you see files in Bootcamp Volume?
Test 3 - Can you select Bootcamp in System Preferences -> Startup Disk?
Test 4 - If Test 3 is successful, select Bootcamp and Click Restart
If you see a hanging underline cursor at the top left on a black screen, and it does not proceed further, you may need Windows Startup Repair or a tool called EasyBCD.
