Q: Bootcamp win8.1 autorepair fail after yosemite upgrade

Hello Loner T,

 

I try to post directly here, as my problem is quite similar to another you answered before Loner T.

I have read most of your posts on reporting diskutil and testdisk

I have testdisk and gdisk ready to use

But, yes theres is a "but" :-), i got a different display that seems more complex to me... i got 5 partitions and the one that seem to be the right partition is the 5th and the 4th dont remind me anything.

 

Here are my outputs :

Oops i forgot some details

At boot bootcamp never disappeared

Windows 8.1 bootmgr is launching but i think it's not on the right disk (disk 4 contain a strange temp folder and a recovery file) > seen on finder

disk4 has the ntfs header but it's not the right disk

disk5 dont have the same header

As i remember there are only 4 partitions on my computer...

 

And it's not possible to mount disk5

 

I have run testdisk, could you help me on the output pls ?

That upgrade is going me crazy... :-D

    And to answer you, what do you mean by install ? The first one or my upgrade to yosemite ?

    Yes i have an Hybrid MBR as reported on gdisk :

     

    pc12:testdisk-7.0-WIP Denis$ sudo gdisk /dev/disk0

    Password:

    GPT fdisk (gdisk) version 0.8.10

     

    Warning: Devices opened with shared lock will not have their

    partition table automatically reloaded!

    Partition table scan:

      MBR: hybrid

      BSD: not present

      APM: not present

      GPT: present

     

    Found valid GPT with hybrid MBR; using GPT.

    What year/model is this Mac?

     

    If you have an MSR and a Hybrid MBR, it makes no sense. Do you remember if prior to upgrade you had four partitions or five?

    What's an MSR ? You mean ... MBR maybe ?

    I only see Hybrid MBR in Gdisk, but maybe i'm wrong ?

    If you look at disk0s4, it says Microsoft Basic Data System Reserved. I have seen such partitions when Windows disk part was used on a disk.

     

    Can you post the NTFS header that you see on disk0s4?

     

    It is likely that Yosemite split it mistakenly.

     

    As a quick test,

     

    1. Delete GPT#4 and GPT#5 via Gdisk.

    2. Create a new GPT#4 with start at 287242240 and size of (184739840 + 1269760 ) = 186009600.

    3. Create new Hybrid MBR using this new GPT.

    4. Check if you can see Bootcamp volume in Finder and your files.

    5. Try starting Windows via Startup Disk.

    This looks good. If you need help with the Hybrid MBR, take a look at Yosemite Upgrade Broke Bootcamp for steps.

    PARTITIONS!!

     

    Do you want to proceed? (Y/N): Y

    OK; writing new GUID partition table (GPT) to /dev/disk0.

    Warning: Devices opened with shared lock will not have their

    partition table automatically reloaded!

    Warning: The kernel may continue to use old or deleted partitions.

    You should reboot or remove the drive.

    The operation has completed successfully.

     

    I reboot and tell you the result.

    Thanks anyway for your help until now. You have participated a lot to help the community on this problem :-)

    I don't have the bootcamp at boot anymore.

    Just Macintosh HD.

    For me this means i didnt rebuild the HybridMBR.

    Should i do it right away ?

    Yes, please do. The delete/add just modified the GPT, but the Hybrid MBR needs to be rebuilt as well.
