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.

    Can you use fdisk -e and change Partition number 4 to type x'07' and flag it as bootable?

     

    There are quite a few examples of how to do it or if you are comfortable with using Unix man pages, then you can execute man fdisk in a Terminal window on your Mac and use setpid and flag commands. You will also have to use write and reboot, if required, after you make changes using fdisk.

     

    You may still get Missing OS errors, but these can be fixed using Windows Recovery Console.

    Could you be a bit more specific with what to do Loner T? I'm not that well known with ios.

     

    Did you mean for me to type those into the terminal as commands?

    Please look here...

     

    https://discussions.apple.com/message/22243032#22243032

     

    In Mac OS X Terminal, do the following

     

    sudo fdisk -e /dev/disk0

    print

    setpid 4

    07

    flag

    print

    write

     

    Now reboot. Check if holding the ALT/Option key will show the Bootcamp partition. If it does, MAC OS X is now happy, but you may have to still use Windows Recovery Console.

    I'm really sorry for not knowing what to do.

    Alright sorry for not reading the link you gave me. So all i have to do now is just use Windows recovery console and everything should be back to normal am I right?

    It depends on how much "damage" was done during resizing. It is also possible to re-install Windows (without losing your personal data), but I would recommend the Windows Recovery console first and you may need to use fixmbr or similar tools.

    Alright, I'm back tried using windows recovery tools but it failed to repair it with startup repair. Gonna try something different maybe. Thanks for the reply and answer good sir

    You last recourse may be a re-install of the Windows OS only. If that does not work, I assume you have a backup of your Bootcamp partition. Do you want to consider trying WinClone?

    bad thing is, i had a backup but my external hd got messed up and i dont know what happened to it. winclone is quite pricey tbh. Startup Repair said that the boot something was corrupted. does that ring a bell?

    i just read about something typing in to the command prompt within the Windows Recovery Console, like this

     

    bootrec.exe /fixmbr

    bootrec.exe /fixboot

     

    would this help?

    If you can recall the message from 'Startup Repair', it may help in deciding which option(s) of bootrec.exe to use.

     

    In the Microsoft KB 927392 link I mentioned previously, you can see the list of qualifiers supported by bootrec.exe.

    Yeah i saw that, something about the boot disc sector is corrupted i think. And its hard disk drive was actually x: instead of the natural c:. I tried getting to c: drive but told me that it needs to be reformatted so i didnt do it.

     

    i also noticed this

     

    Disk: /dev/disk0geometry: 60801/255/63 [976773168 sectors]

    Signature: 0xAA55

    the one with the bold letters

     

     

    EDITED: made me wonder why the startup repair couldnt find the windows 7 OS told myself yeah, thats whats been missing and trying to repair it wont be that easy.
