Q: Bootcamp no longer bootable after adding and deleting partitions

I am using a 2014 Macbook Pro with OSX 10.9.5

 

I was trying to add a partition to install Ubuntu on and after adding and deleting partitions, my bootcamp partition will no longer boot whether I use rEFIt or bootcamp assistant or normal osx boot menu.

 

Judging from the information I got from similar threads on this I think this information will be useful

It wasnt like this before. Before 3 and 4 had some of the same values from above instead of all 0s. After trying to take advice from threads with similar problems and entering stuff into the command line it became like this. I think I might have messed thing up while looking for a quick fix.

 

Can anyone help me with this? Thanks.

    I have done some resizing partitions in disk utility. Bootcamp still doesn't work however.

    From Boot Camp 5.1: Frequently asked questions - Apple Support,

     

    Can I resize the Windows partition after installing Windows?

    No. Back up your important files, then use Boot Camp Assistant to delete the old partition and create a new one.

     

    Any failed attempts can cause data loss.

     

    Can you use Bootcamp partition missing after yosemite installation as a reference and get started with Testdisk?

    I started with testdisk and I've gotten this far:

    Use Right to change directory, h to hide Alternate Data Stream

        q to quit, : to select the current file, a to select all files

    C to copy the selected files, c to copy the current file

     

    According to the thread you linked to and this other thread "System Volume Information" is a good sign that I'm in the right partition.

     

    At this point in both threads you post some numbers (which I can't copy and paste due to formatting issues) about GPT start end size as well has NTFS start end size and offset.

     

    I've figured out where some of the numbers come from but I have no clue how to determine NTFS offset and some other numbers.

    Sorry. I forgot to inform you that I did a little more resizing in disk utility since my original 2 posts. This is what my disk looks like now:

    I'm not sure how to edit my replies so I'm just gonna make another reply. I assumed the following values:

     

    GPT 3 StartGPT 3 EndGPT 3 SizeNTFS StartNTFS OffsetNTFS EndNTFS Size
    29337838429338032019362946498561936490233855195584000

     

    I followed the rest of the instructions given here. I made sure to enter the second number with a + sign. After doing all of that all these checks worked:

     

    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?

     

    I've always been able to access my bootcamp files from finder and I can try to boot from System Preferences -> startup disk, from rEFIt and also from my macbooks startup manager that I access by holding down option while booting.

     

    I'm starting to think I've misrepresented my problem and that I've been looking at the wrong threads. Every time I try to boot windows I get a black screen with the Windows logo and some text saying something like "starting automatic recovery" or something like that. It then takes me to a blue screen displaying an error number and telling me to use recovery tools on the installation media. Maybe this is different from the problems I've been looking at in other threads.

     

    I've tried using the same USB I used to install bootcamp with but it doesn't give me the option of repairing the installation.

     

    EDIT: So I figured out how to edit replies. Anyway I just tried to boot into Windows and checked. The black screen with the Windows logo says "Preparing Automatic Repair". The blue screen gives me the error 0xc00000e.

    If you are seeing a BSOD and Automatic Repair, are you on Windows 8+? If yes, you should complete the recovery. Your table is using the same partition offsets as original layout.

     

    Can you post the output of

     

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