Q: Bootcamp (Win10) didn't start after el Cap. update

Hi Loner,

I have the same problem after updating to capitan :-(.

It's then same sh..t as when I updated to Yosemite before.

Bootcamp is still there but when I choose it Bootsector is not found.

The el Capitan update was also not successful in the first try. I saw the symbol for no OS found  (Circle like stop sign).

Then I installed it again under Service Console (CMD+R) and it worked then but bootcamp i still broken.

I can see the partition and open Files from MacOS but boot sector is not found.

 

 

 

Here are the result of diskutil:

A:

You have ELC System Integrity enabled.

 

1. Boot into Local Recovery.

2. In Utilities -> Terminal type

     csrutil disable

3. Boot normally.

4. Execute Gdisk steps and test and verify.

5. Repeat Step 1 and type

    Let us try the simpler update. If you have ELC, you want to put GPT Fdisk in /usr/local/bin otherwise you have to disable System Integrity Protection. Once GPT Fdisk ( http://sourceforge.net/projects/gptfdisk/ ) is installed use the following steps. The following steps assume you have GPT Fdisk in /usr/local/bin .

     

    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 /usr/local/bin/gdisk /dev/rdisk1
    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.

    You do not seem to have an existing bin  directory. Run sudo mkdir -p /usr/local/bin and then copy the gdisk binary to /usr/local/bin.

    sorry for my noob question but

    why I can't make such dir?

    Markuss-iMac:/ markusplecher$ sudo mkdir -p /usr/local/bin

    mkdir: /usr/local/bin: Not a directory

    Markuss-iMac:/ markusplecher$

    Because you currently have a file called bin (a copy of gdisk) sitting in that location.

     

    sudo rm /usr/local/bin

    sudo mkdir -p /usr/local/bin

    sudo cp -p /usr/sbin/gdisk /usr/local/bin/

    sudo /usr/local/bin/gdisk -l /dev/disk0
