    Can you post the output of

     

    sudo gpt -vv -r show /dev/disk0

    sudo dd if=/dev/rdisk0s5 count=1 2>/dev/null | hexdump -C

     

    As long as the NTFS header shows up, the next step would be to create a new Hybrid MBR which is different from the standard. The above two commands will help in that procedure.

    The following steps are not the same as a standard Hybrid MBR build. Please ensure that you accept the default values for MBR hex codes for partitions otherwise you will not be able to use OS X or Windows. You are updating ONLY the boot flags, nothing else. Do no partition the disk using ANY utility, otherwise you will lose data. If you see any errors, please stop and stay at the step you are at. It would also be helpful to capture the screen completely before the Reboot step and post it for validation. Please post the output of sudo fdisk /dev/disk0 before the reboot as well.


    Rebuild MBR to match the new GPT information thus resetting the Hybrid MBR. Use defaults for other questions (like partition MBR hex codes).

    1. Sudo gdisk /dev/disk0
    2. P  (Print list of parts)
    3. R   (Recover)
    4. H (chooses Hybrid)
    5. Partitions numbers to be hybridized: 2 4 5
    6. Y (Good for GRUB question)
    7. N (part 2 boot flag)
    8. N (part 4 boot flag)
    9. Y  (part 5 boot flag make NTFS bootable partition)
    10. P
    11. W  (Write the new MBR)
    12. Y    (Yes! write the new MBR)
    13. 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.

    it boots windows however, it stays frozen and doesn't proceed to login just stays on the starting windows page.... Tried running windows startup repair (holding F8) but it said that it could repair the problem... Sending images or error codes

    Do you have the Windows Installer media? You may have a corrupted BCD.

     

    Please take a look at https://neosmart.net/wiki/bootrec/

    I do have the installer media for Windows 7 Home Premium however, I tried and ran all of the commands from the wiki link you recommend that I view, but still nothing. I did get all of these error codes and it told me that these are the problems. Maybe you can make something of this.

     

    With that said, these are my thoughts and questions.

     

    A.) Will I be able to run windows and have all of my applicatiosna nd programs from before?

    B.) Can I copy all of my fiels and prgroams (basically copy everything on bootcamp to a folder and then wipe the windows partition an dthen reinstall windows and then drag all of these back to bootcamp on the apple side again in order to have it back to normal? or will that not work? I have adobe products an di dont have the access keys anymore... I also dont have the access keys for other programs instaled too... really need it to wortk.

     

    thanks

    1. Can you post the error codes (or screen shots) of the errors you get when Windows is trying to restart?

    2. A. If the current installation can be recovered, then yes.

        B. The OSX side provides a default NTFS driver, which allows read access, but not read-write. There are third-party products like Tuxera,

               Paragon, NTFS-3g, which do allow read-write access.

    3. There may be a way to extract keys. Look at BelArc Advisor.

    In http://support.microsoft.com/kb/927392 there is a procedure to delete the old BCD and re-build it. Can you use this to rebuild your BCD?

    1. For Testdisk use /dev/rdisk0. Use the "sudo" and you can safely ignore the read-only disk message. Please see https://imgur.com/a/PjmnK for the initial Testdisk screens.

    2. The DD command needs /dev/rdisk0s4.

    3. The Gap between GPT3 and GPT4 is most likely you culprit. Did this happen after the Yosemite upgrade?

    4. Your disk layout seems very strange. What is the 1.4GB /dev/disk7?

    3.

    I think it happened after the Yosemite upgrade. I haven't used Bootcamp for months, lots of Googling led me to conclude Yosemite was the culprit.


    4.

    /dev/disk7

    I have no idea. How would i find out?


    My goal is to get Bootcamp and Windows working again. I'd much prefer not to have to start from scratch if possible but need to find a solution reasonably soon.


    Thx
