Q: bootcamp partition no longer mountable

I was trying to get OSX to be able to read the 2 Windows partitions( named System and Data repectively). Maybe due to installations of Paragon and Tuxera, now the System partition no longer mountable in OS X,  the Data partition is still accessible.

 

I have read LonerT's instructions to other similar problems, and here are the results of those routine checks:

is it normal that fdisk has only 1 line? should have at least 4 here?  Testdisk can't print out filenames, reporting something is damaged...


Please HELP!! Many Many Thanks!!

    Hold on, I'll try to get a BootCamp expert over here, it may take a while (you have too many partitions, but I can't tell you how to fix it)

    I have placed the call, but I have no control over how long it may be before he turns up, sorry

     

    I would leave it alone until he does.

    Please hold back on Testdisk, unless we need it. Can you post the output of the following commands?

     

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

    sudo dd if=/dev/rdisk0s5 count=1 2>/dev/null | hexdump -C

     

    We need to check headers. You will most likely need a hybrid MBR using 3 4 5 rather than the standard 2 3 4.

    Which of the two partition is a bootable W8.1? I assume System is. What is the year/model of your Mac?

     

    You seem to have an EFI Boot installation of W8.1 since you reference winload.efi. Is that correct?

     

    Can you disable Paragon and test?

     

    Please also see https://kb.paragon-software.com/article/204 and this part...

    It should be noted that the NTFS for Mac boot selector doesn’t work for Boot Camp configurations using a pure GPT disk layout instead of hybrid GPT. This applies to Macbook Airs from mid-2013 and later, and Macbook Pros and Mac Pros released in late 2013 and beyond. On those systems, you need to use the Option boot selector for booting into Windows, unless it’s installed to a pure MBR disk.

    You have a pure GPT disk as the Fdisk output shows.

     

    This link - Re: Can't resize Macintosh HD partition - will let you mount the EFI partition (disk0s1) and check for a Microsoft directory.

    The win8.1 blue screen looks like this

    Use F8 and boot to Safe Mode with Command Prompt. You will need to run sfc (System File Checker). Please also see

    https://support.microsoft.com/en-us/kb/929833

     

    You will need to use syntax similar to

     

    sfc /scannow /offbootdir=d:\ /offwindir=d:\windows

    The /offbootdir= option specifies the drive letter, while the /offwindir=option specifies the Windows path, again including the drive letter.

     

    Choose offbootdir and offwindir by checking diskpart and verifying your drive letters.

    paragon NTFS and Texura NTFS have been uninstalled immediately after this problem detected.

     

    following the instructions from the other thread I did the following:

     

     

    >sudo mkdir -p /Volumes/EFI

    >sudo mount -t msdos /dev/disk0s4 /Volumes/EFI

    got error message from Terminal :

     

    "mount_msdos: /dev/disk0s4 on /Volumes/EFI: Invalid argument"

     

    and from system.log:

     

    "kernel[0]: msdosfs_mount: invalid total sectors (0)"

     

    the System partition seems to be in bad condition, it is grayed out in the disk utility as posted above. 

     

    I didn't know what makes the System and Data partition reappeared in disk utility window... at the beginning none show up, only one MAC drive is listed, also in diskutil list report at the beginning of this post, you can see disk0s4 has  "Untitled" rather than "System", as of now, Data partition works just as normal.

    These can corrupt files due to conflict between OS X and third-party drivers. Uninstalling will not undo the damage already caused.

    You need to mount disk0s1, not disk0s4. We need to check the EFI partition for a Microsoft directory.

    You will need to run chkdsk on your C: drive. If that does not correct the problem, then SFC is needed. Manual modifications to disk0s4 or disk0s5 can make things worse. Disk0s4 should only be manipulated using SFC and chkdsk and supported commands. Do not use any OS X utilities to manipulate either partition.

    pressing F8 at the blue screen does not do anything

     

    okay, my bad   mounting /dev/disk0s1  to /Volumes/EFI   is okay.   What reports do you need here? 

     

    it has BOOTLEG  EFI/,   in EFI/ it has APPLE/ Boot/ Microsoft/  ...

    It is an EFI installation. Can you check if Fn+F8 or Shift+Fn+F8 or Shift+F8 allow you to get to Startup Settings?

     

    After removing/disabling Tuxera/Paragon, can you see both NTFS volumes in OS X Finder?
