I can still access my boot camp partition through Parallels but it is no longer an option to boot to when starting up.

    MacBook Pro (Retina, 15-inch, Early 2013)

    Windows 10 Pro Version 10.0.14393 Build 14393

     

    I upgraded to Windows 10 a few months ago and everything was fine until the macOS Sierra update.

    Which third-party tool(s) were used to modify/resize the partitioning? The typical ordering is

     

    EFI, OSX, Recovery HD, Bootcamp, but you have the incorrect order and an extra Recovery. Were there two version of OS X at any point on this Mac?

    I used iPartition to resize it several months ago, before upgrading to Windows 10. https://coriolis-systems.com/iPartition/

    Did Windows work before the W10 upgrade and after the iPartition changes? With two Recovery HDs, your protective MBR is one problem. The 2013 Macs support both EFI and BIOS installations. Do you recall if you installation is EFI or BIOS? If not, then there are a couple of extra steps needed to determine that.

     

    Did iPartition fail (or partially succeed) leaving a copy of Recovery HD? Can you check if a Reboot with Command+R brings up Local Recovery? Also, if you boot, and hold Alt/Option key, do you see two Recovery entries?

     

    Do you have back ups of OS X and Windows?

    Windows worked after the iPartition changes. Then I upgraded to Windows 10 and it worked fine. Then I upgraded to macOS Sierra and it doesn't show up as a boot option. 

     

    Holding option only brings up two options: Recovery-10.11.2 and Macintosh HD. Command+R brings up OS X Utilities.

     

    I don’t remember if it was EFI or BIOS.

     

    macOS is is backed up on Time Capsule. I don't have a backup of Windows.

    Can you install GPT Fdisk - https://sourceforge.net/projects/gptfdisk/ ? If you know how to create a Hybrid MBR using Gdisk, create one with GPT 1 2 3 and mark GPT 1 as bootable.

    I installed gdisk but don't know how to use it. Can you post instructions? Thanks.

    Let us try the following configuration and take a look at resulting 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: 1 2 3
    7. Y  (Good for GRUB question)
    8. Y  (part 1 boot flag make NTFS bootable partition)
    9. N  (part 2 boot flag)
    10. N  (part 3 boot)
    11. O  (print current Hybrid MBR)
    12. W (Write the new MBR)
    13. Y (Yes! write the new MBR)

     

    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 #1 (MBR partition #2)

    Enter an MBR hex code (default 07): Press Enter/Return

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

     

    Creating entry for GPT partition #2 (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 #3 (MBR partition #4)

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

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

    It asks if I want to overwrite current partitions. Will that erase my data on the boot camp partition?

    We are not changing partition content, but only partition layout/boundaries in the MBR. This is derived from the GPT, so there is no data content being manipulated.

     

    I assume that you have back ups.
