Q: Bootcamp missing after resizing manually

I know i have seen many threads, discussions about this kind of problem. Sorry if this is posted in here if its the wrong place I mean.

Well I did some reading and wasnt so sure about going further than what I've seen was successful for others (scared to damage or lose any files on my bootcamp).

 

I did resize it once, and it was successful, but this time it just suddenly turned to a disk0s4 and has an amount of the very first partition I had for the bootcamp (before resizing it successfully)

 

Thing is I'm not that confident without proper help or guide in repairing and any help would be greatly appreciated. I'm online this very moment and day I just want to wrap this up as I won't be able to sleep knowing that my sister's thesis report are in that bootcamp.

 

Here is so far what i have done.

 

gpt show: disk0: mediasize=500107862016; sectorsize=512; blocks=976773168

gpt show: disk0: Suspicious MBR at sector 0

    Can you add the following to the MBR (fdisk -e)?

     

    4: 0C 1023 254  63 - 1023 254  63 [ 394345320 -  195796992] Win95 FAT32L

     

    and flag it for bootability?

     

    Can you also post the gpt and fdisk output after you do this?

    Partition id is either '0C' or '07'.

     

    Cylinder/Head/Sector should have defaults of 1023/254/63 in both Starting and Ending columns.

     

    Start

    394345320

     

    End

    This is all done in fdisk. Once you do the write (similar to the setup you did for changing Partition id), post your fdisk output before any further steps. Cylinder/Head/Sector should be already populated with defaults.

    Can you also post the gpt output?

     

    Can you do 'setpid 4', flag, write and reboot? Now see

     

    1. if ALT/Option key will show up the Windows as bootable, and,

    2. Does the BOOTCAMP volume mount and is it accessible from OS X Finder?

    shows up as bootable, but the bootcamp volume remains disk0s4 and is not accessible on OS X finder.

     

    Tried to mount it but to no effect. I'll see to your answers maybe later and then give it a shot again, right now i gotta sleep its 5am already. Thanks for the time and help dear sir

    The Bootcamp volume is not expected to change with what we have done so far. It should stay disk0s4, and diskutil should confirm that.

     

    PLease look at Console log and in DU, if you enable debug mode, we can see what is the volume and file system type.

     

    We can take it up once you have had some sleep.

    In the Microsoft link in this thread, bootrec.exe /scanos using Windows recovery seems to be the next logical step.

     

    It would be good to record diskutil list, gpt and fdisk outputs here.
