    Have you executed a Deeper Search before this point? If not, press Enter to Continue, but be aware that this can a long time.

    It looks like you are re-executing the Deeper Search again. You may have to let this search finish. When you see the screen with partitions listed and see an option for 'P - List Files', then choose the one highlighted below.

    Im having this problem and I really need help. I believe you can help me Loner T. Thank you!

    Since bootcamp was not staring I found the solution you posted:

    ·         sudo fdisk -e /dev/disk0

    p

    setpid 4

    07

    flag 4

    p

    write

    y

     

    After this windows is just getting stuck at boot (black screen with blinking cursor)

    Can you start a new thread to avoid confusing two separate issues?

    This is a list of partitions which cannot be recovered. Press Enter to Continue and you should get a list o partitions you can work with.

    Do not use left/right arrow keys. Use only up/down arrow keys and use 'P - List Files'.

     

    Please use P to list files look at the fourth and fifth entries which say MS Data. The fourth entry looks the most likely candidate.

    Here is table that I use  for validation. Please read the two Gdisk command sequences. If you have any questions, please ask, before you proceed.

     

    GPT 3 StartGPT 3 SizeGPT 3 EndNTFS StartSector OffsetNTFS SizeNTFS End
    82117144012695368224409768224419841008154662905

    977104889

     

    Leave your Testdisk display and start a new Terminal Window. Please 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

     

    1. Sudo gdisk /dev/rdisk0
    2. P  (print the full list of parts)
    3. D  (delete)
    4. 4  (part 4)
    5. N  (new part)
    6. 4   (part 4)
    7. 822441984 - Start offset in bytes  (start point for Bootcamp part)
    8. +154662905 - (Size offset as opposed to End offset)
    9. 0700     (Windows part type)
    10. P           (print list of all parts just to see what changes will be made)
    11. W         (Write the new GPT)
    12. 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). The only values that need modifications are the Boot flags and step 6. Accept all other defaults that Gdisk offers.

    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 3 4
    6. Y (Good for GRUB question)
    7. N (part 2 boot flag)
    8. N (part 3 boot flag)
    9. Y  (part 4 boot flag make NTFS bootable partition)
    10. W  (Write the new MBR)
    11. Y    (Yes! write the new MBR)
    12. Reboot

     

    Here is an example Q&A session with Gdisk.

    Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N): Y

     

    Creating entry for GPT partition #2 (MBR partition #2)

    Enter an MBR hex code (default AF): Press Enter/Return

    Set the bootable flag? (Y/N): N

     

    Creating entry for GPT partition #3 (MBR partition #3)

    Enter an MBR hex code (default AB): Press Enter/Return

    Set the bootable flag? (Y/N): N

     

    Creating entry for GPT partition #4 (MBR partition #4)

    Enter an MBR hex code (default 07): 07

    Set the bootable flag? (Y/N): Y

     

    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.

    You forgot the '+' sign. Look at step 8.

    Was I supposed to type N for Enter an MBR hex code?
