Q: Can't find Bootcamp Partition

Hi, I have similar problems with the Bootcamp issue that everyone has after installing Yosemite. Can you please help me? I'm really not at all a techy person and I've read a lot of threads on this issue and I just don't understand how to do any of this. I've download Testdisk and GDisk but I don't know what to do from there. I don't want to mess up any of my files so can you take me through this step by step? Sorry if I ask stupid questions because I really don't know anything about computers in general.

    From OS X terminal run sudo testdisk /dev/rdisk0 (or wherever you downloaded Testdisk to).

     

    The goal is to find the 'lost' NTFS partition using the step-by-step link I posted on the previous thread.

    So is there a way to run testdisk through OS X terminal? I typed that in and it didn't work. I do however have a completely different program called TestDisk and when I go onto it, there's 3 options called Create, Append, and No Log. Which do I choose to find the 'lost' NTFS partition?

    My Testdisk is located in the Downloads folder. The first you use Create, but subsequent iterations should use Append, so that you have a single log which can be used to look at history, if necessary.

     

    Choose EFI partition type. It will show you the current configuration and Quick Search which you should execute. Look at each MS Data partition for familiar files. If the start/end/size in Testdisk match the current GPT4 start/end/size, it is unlikely to be valid, otherwise you bootcamp/windows should already be working.

    Quick Search will usually finish quickly. The Deeper Search can take hours.

    The following two look the most interesting. My guess is the second entry makes the most sense and is the closest to the combined size of the current GPT4 and the Gap size. Please look in these two using 'P' to list files. Do not use left/right arrow keys.

    D MS Data                247001088  490233848  243232761


    This looks like your current GPT4 and is not very interesting because it is the incorrect size.
