Q: Bootcamp no longer boots after creating third partition

Hello;

 

I wanted to add El Capitan as a third OS to my existing Yosemite and Bootcamp (Win 8.1 Pro) dual partition set up.

 

I have done the following:

 

Reduced the size of the Yosemite partition

Deleted the Yosemite recovery partition

Created the third partition

Installed El Capitan

 

Now, I am no longer able to boot to the Bootcamp partition. Attempts to do so result in the following message.

 

NO BOOTABLE DEVICE - INSERT BOOT DISC AND PRESS ANY KEY

 

I'd prefer to fix the bootcamp partition rather than formatting and reinstalling. Might someone be able to assist?

 

Thank you in advanced

MacBook Pro (Retina, Mid 2012), OS X El Capitan (10.11), Triple partition boot

    You have El Capitan, so we need to disable SIP.

     

    A. 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. Correct the MBR for Windows boot ability. Please ignore the i386 MBR error message, but not any others.

     

    sudo fdisk -e /dev/disk0

    p

    setpid 4

    07

    flag 4

    p

    w

    y

     

    Reboot and check if you can see the BC Volume and files in the volume using Finder. If you can, use System Preferences -> Startup Disk, click on the lock icon and choose Bootcamp and click Restart. If everything works normally re-enable SIP using csrutil enable and the method in Step A.

    The safest method is to backup you files and re-install Windows to resize Bootcamp/Windows. You can also look at Winclone or CampTune.
