Q: Boot Camp not visible after booting with the option key

Boot Camp disappeared after El Capitan update

My Boot Camp disappeared after the El Capitan update. I thought I fixed it on this way Boot Camp disappeared after El Capitan update

And it partly did, I can see bootcamp in disk utility now. And I can see my files in bootcamp. The only problem is that I still can't boot windows. When I'm booting my Macbook with the option key I don't get the choice to boot Windows.

What I noticed in the Disk Utility program (it's in dutch) is that it says it's not suitable for start-up.

    The boot ability of Windows is determined usually by the MBR. Can you post the output of the following OS X Terminal commands?

     

    diskutil list

    diskutil cs list

    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.

    Please post the output of

     

    sudo dd if=/dev/rdisk0s4 count=1 2>/dev/null | hexdump -C

     

    We need to check the header of the BC/Windows partition.

    A. We need to disable SIP.

     

    1. Boot into Local Recovery (Command+R).

    2. Start Utilities -> Terminal.

    3. Type csrutil disable in Terminal and press Enter/Return.

    4. Type csrutil status.

    5. Boot normally, and type csrutil status to confirm that all individual entries are still disabled.

     

    B. Rebuild standard MBR.

     

    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. Please see the sample Q&A as an example. These steps can be repeated if you make a mistake before you get to Step 12, otherwise start from Step 1 for these steps. Step 6 has numbers which are typed with a space between the numbers. Please see the sample Q&A before you execute these steps.

    1. Sudo gdisk /dev/rdisk0
    2. P  (Print list of parts)
    3. R  (Recover)
    4. O (print current Hybrid MBR)
    5. H (chooses Hybrid)
    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.

    Great it's working! Thank you very much! Only thing is that my recovery HD disk still is gone. Is that partition #3?

    Can you test command+R and command+Opt+R, both? This will test local and internet Recovery.
