Q: Boot Camp disappeared after installing El Capitan

Hi, I have a lot of important files on my windows 8.1 Boot Camp partition and they were not backed up recently.  I upgraded from Yosemite to el capitan OS X 10.10 this afternoon and the screen froze on reboot and then booted into windows with an error.  After I rebooted it back into OS X it continued with the install however the Boot Camp partition is not visible from the disk utility although you can see it and select it upon pressing on the Option key during startup.  If the windows partition is selected a recovery error is shown for windows, even with the usb key inserted.

 

Macbook Pro mid-2014 1TB SSD  Approximately 700G OS X and 300G Windows 8.1

 

Here are my results from the terminal prompt tests mentioned in earlier threads.

Any help is appreciated, working on figuring out how to run test disk from the command prompt.  New to macs.

Thanks!

    ok OS X is cloned.  It doesn't appear that any of those 3 will work with my bootcamp situation since bootcamp doesn't appear in the file utility.

     

    here is the file GPT output

    Which has also been cloned.

    We need to reconstruct this layout using Gdisk.

    The sector addresses are correct, but the partition types are incorrect. You will need to use Gdisk 't' command for GPT 3 and convert it to a GPT disk.

    I'm still trying to find information for the 't' command that shows steps on how to accomplish that.  Nothing so far for 't'

    Disabled SIP using csrutil in the online recovery terminal.

     

    Haven't found the information about which type code to change partition 3 to yet.  Tried to find the original type code for that partition as well in my saved screenshots but no luck so far.

    From my previous post (output of the 'l' command), af05 is Core Storage.

    Here is where I am now:  selected GPT and command 't' partition number 3 which shows as Recovery HD and entered GUID af05

     

    Is this correct?

    GPT2 (OSX Core Storage) has a code of AF05, GPT3 (Recovery HD) has a code of AB00. If you notice in the two screen shots I posted, the long string is different only for GPT2, but the rest are the same. AF05 for GPT2 will get translated to 53746F72-6167-11AA-AA11-00306543ECAC which will match the older layout.

     

    Please also see https://en.wikipedia.org/wiki/GUID_Partition_Table as a reference.

    Ok that makes sense.

     

    Although I turned off SIP I still get the error when loading gdisk.

     

    Here is where I am now:

    Try it. With SIP Disabled, it should work. If it does not, disable SIP again, and try it. NVRAM Reset can change SIP state.

    so I used 'csrutil disable; reboot' from the terminal in internet recovery

     

    Here is the output

    Is this SIP related or some other issue?

    You cannot use Internet Recovery (Command+Opt+R - Spinning globe recovery). You need to use Local Recovery (Command+R).

    Well I used command + R and all it will give me is the internet recovery.  Any idea how to get local recovery to come up? other than command + R
