Q: Boot camp parition missing after upgrade to OS X Yosemite

Lately I upgraded my Mac OS X to Yosemite, and my Boot camp parition is gone.

It would be nice if someone would help me to recover it.


$ diskutil list

I've followed the instructions: http://nerdr.com/bootcamp-partition-lost-repairing-mac-partitions/ and added partition 5 to MBR, now when my mac is booting up and I hold ALT key, I can choose Windows, but when I do there is info: Missing operating system.

 

Is there any way to fix it?

 

Thanks!

MacBook Pro, OS X Yosemite (10.10.1), half of 2010

    You do not have a valid NTFS header. You will need Testdisk and GPT Fdisk (disk).

     

    Please see Bootcamp partition has disappeared after upgrade to Yosemite 10.10 as an example of the next steps.

    How was this specific configuration created? You have a 9.6GB HFS+ as GPT#4. Can you please describe the partition changes made to this Mac in the past?

    Did you have two versions of OSX at some point on this Mac?

    First I created boot camp partition with 30 GB, next I extended it to 40.

     

    Now I've got only one version of OS X.

    Resizing Windows or adding/removing partitions creates many issues. If Testdisk cannot find the appropriate header, there may not be an option other than re-installation of Windows after creating a single-partition OSX disk.

     

     

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

    Can you post  the output of

    sudo dd if=/dev/rdisk0s5 count=1 2>/dev/null | hexdump -C

    since your fifth entry (disk0s5) is Bootcamp, not disk0s4.

    I've posted it before, when you asked me to do it for the first time.

    Ah, I see it now. There is no NTFS header on rdisk0s5.

    Can you check these entries from your Testdisk output, for files?

    D MS Data                156659712  234440696   77780985

     

    The first three entries are located somewhere in your OSX partition and may be damaged. This is your GPT3.

     

    155652248    1269536      3  GPT part - 426F6F74-0000-11AA-AA11-00306543ECAC

     

    If the following table is used to look at the last entry that I have listed in the four MS Data entries, I get

     

    GPT 3 StartGPT 3 SizeGPT 3 EndNTFS StartSector OffsetNTFS SizeNTFS End
    1556522481269536156921784156659712-26207277780985234440697-127.9648438

     

     

    NTFS Size is roughly 37+ GB, and this partition is about 127MB inside your Recovery HD, which means you will lose GPT#4 and parts of GPT#3. It can be tested, but Testdisk should be used first to look for familiar files first.

    I've checked all.

     

    In most of them there is the same info.

     

    In few of them there is only one entry System Volume Information.

     

    In one I found more entries but names weren't familiar to me.

    The size and dates indicate bad corruption in the MFT. Are there any other MS Data entries in Deeper Search output?

    I've posted the whole list earlier, there is about 20, and I've checked all of them.

     

    I think I'll have to deal with it
