Q: Boot Camp missing after upgrade

Odd that I waited so long to upgrade and Apple still hasn't fixed this.  I wasn't even aware of this being an issue until I decided to use up my bandwidth and download the upgrade.  Any help on how to get my Windows Back?  A few work utilities are PC only.

    Please post the output of the following

     

    sudo gpt -vv -r show /dev/disk0

    sudo fdisk /dev/disk0

     

    The "sudo" commands will prompt for your password, and it will not be echoed back. You may also see a warning about improper use of "sudo" and potential data loss due to "abuse" of the command.

    The gap between GPT3 and GPT4 is where a lost NTFS header is sitting.

     

    Please download the following two utilities

     

    Testdisk is available at http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step.

    GPT Fdisk is available at http://sourceforge.net/projects/gptfdisk/.

     

    Start Terminal from Applications -Utilities -> Terminal and run Testdisk from the directory where it is downloaded. For example, I have it in the Downloads directory,

     

    ls ~/Downloads/testdisk-7.0-WIP/testdisk

    /Users/MyName/Downloads/testdisk-7.0-WIP/testdisk

     

    and I run it as

    sudo ~/Downloads/testdisk-7.0-WIP/testdisk /dev/rdisk0

     

    You should see a UI similar to https://imgur.com/a/PjmnK .

    I tried to follow the images on https://imgur.com/a/PjmnK -

     

    After it took almost 24 hours to do a scan, I got to the 'Deeper Search'.  That ran another 24 hours... after that, I continued until I got back to what looks like the main menu.  I went to disk utility and saw disk0s4 - So I rebooted the computer and held the option key down to try to boot to windows.  No windows partition found.

     

    Did I do something wrong?  or am I out of luck?

     

     

     

    Thanks again. iD

    Testdisk allows you to inspect partitions that are recoverable. It does not fix any issues. Once you finish Deeper Search, the list of partitions need to be inspected using 'P - List Files' option to check if any of the partitions listed may be viable and contain the correct Windows header. Unfortunately, you will have to get to this list, before any further recovery is possible. Can you post a screen shot of the list of partitions as displayed after the Deeper Search completes? Please stop at this point and post back here.

    I can scroll between the EFI, MS Data, and Mac HFS.  The very last line changes for each one I select - I included in brackets above.

     

    Which one do I select and what do I press?

    Your GPT3 (aka Recovery HD) ends at 1405976048 . The other clue is the gap is 19532304 and 39639040 which adds up to 59171344 sectors (one sector is 512-bytes each) and the two MS Data entries are 59170809. I suggest you select the second MS Data entry and enter 'P' to list files.

     

    Here is a table which lays the numbers out.

    Perfect!  I do see a similar screen.  How can I make it bootable again?

    Leave your Testdisk display and start a new Terminal Window. 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

     

    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. 1405976048 - Start offset in bytes  (start point for Bootcamp part)
    8. +59170809  (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 10. 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. O (print current Hybrid MBR)
    6. Partitions numbers to be hybridized: 2 3 4
    7. Y  (Good for GRUB question)
    8. N  (part 2 boot flag)
    9. N  (part 3 boot flag)
    10. Y  (part 4 boot flag make NTFS bootable partition)
    11. O  (print current Hybrid MBR)
    12. W (Write the new MBR)
    13. Y (Yes! write the new MBR)
    14. Reboot

     

    Here is sample Q&A for this section. Please notice the Press Enter/Return.

     

    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): Press Enter/Return

    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.

    Hey Loner T.

     

    I followed all the steps and no error messages.  But after reboot...

     

    Test 1 - No, therefore... Test 2 - No.

    Test 3 - No.

    The GPT and MBR look correct. Do you have any third-party NTFS software?
