    I think the problem is with this numbers? I read your other solutions.

    I think I have to rewrite GPT partition info with start  875400072?

    No. Your GPT is correct. The MBR needs to be correctEd.

    Please ignore the i386 MBR message in the following steps, but do not ignore any others.

     

    sudo fdisk -e /dev/disk0

    p

    setpid 4

    07

    flag 4

    p

    w

    y

     

    Reboot and test.

    Do you have any third-party NTFS software?

    Yes, I have Samsung External HDD. It installs Paragon NTFS  I think.

    Paragon NTFS driver interferes with the Apple NTFS read-only driver. As a test, can you remove it and then verify that you can see Bootcamp in Finder and in System Preferences -> Startup Disk.

    Re-run the steps that I posted earlier with the Fdisk and test. Disconnect the external Samsung disk before you make changes.
