    Hey

     

    I'm having a similar problem as everyone else in this posting. I have 5 partitions. 3 of which I created for my Mac OS Lion installation, Windows 7 installation and a 3rd for storage.  Everything was running fine for quite sometime until recently. My Windows 7 installation has suddenly stopped booting. Instead of a start up screen I get:

     

    Windows failed to start. A recent hardware or software change might be the cause.


    File: \BOOT\BCD

    Status: 0xc000000d

    Info: An error occurred while attempting to read the boot configuration data

     

    Mac OS Lion starts up fine. I'm unable to mount my "Bootcamp" partition nor the "Storage" partition. On top of that "Storage" has been renamed to "disk0s5". When I installed Windows 7 it didn't recognize the "Storage" partition that was created in Lion so it merged what it thought was free diskspace (I'm assuming the same space that Mac OS recognized as Storage) to the Root Drive of Windows 7 (Bootcamp).

     

    Are you able to assist?

    It doesn't seem similar to everyone else's problem in the thread at all. The error you're getting is totally different. And everyone else experienced their problem right after creating a new partition, while you're saying your problem suddenly spontaneously developed. You wouldn't get this error message if there were partition problems, so you probably need to start out with Windows Startup Repair.

    I've already made attempts to repair the windows installation. The bootcamp partition doesn't mount and the recovery system can't detect a windows installation. I've even tried placing the hard drive into a dock and using a different mac to look at the files. But the partitions aren't even visible

    Well then chances are the volume is toast, I suspect you haven't told us the whole story if OS X is working fine on this drive, but Windows is now failing to boot. Something explains this. Anyway, feel free to post the results from

    sudo gpt -r -vv show disk0

    sudo fdisk /dev/disk0

    You need to install gdisk, create a new hybrid MBR, and add partition 5 to the hybrid MBR, and flag it as bootable.

    There was a failed boot on the Windows side. Windows booted again after removing an audio interface connected through firewire. I don't know what else to tell you.

    For some reason these partitions are only visible on my macbook. If I try to view the drive on another Mac or PC then both systems believe that the drive needs to be formatted.

    Sounds like the volume has become corrupted. You have two Windows partitions on the same disk why? Anyway the Boot Camp partition scheme is already non-standard and you make it even less standard by having 5 GPT partitions when the MBR can only hold four. Not related to your current problem, but your Recovery HD partition is exposed as free space in the MBR implying anything in Windows can choose to overwrite those sectors at anytime without notice. But the GPT and MBR otherwise agree that there are two Windows partitions and the first one is flagged as bootable. So the next thing to do is boot from a Windows DVD and see if you can chkdsk /f both of those Windows volumes and make sure the file systems are clean.

    Hi...thank you for you feedback.
    I already instal gdisk 0.8.5

    And, you told me to "You need to install gdisk, create a new hybrid MBR, and add partition 5 to the hybrid MBR, and flag it as bootable."

     

    How is it?I already install gdisk 085.How can i know the program I installed is succed to install. because I can not see in Aplication/gdisk. 

     

    I use 'terminal' to write command,

    sudo gpt -r -vv show disk0

    sudo fdisk /dev/disk0

    The result is like this.

    Screen Shot 2012-12-01 at 1.30.50 AM.png

    From this result, is it possible for me to get my windows OS back?How?
    Thank you.

     

    My regards,

    (sorry for this long message)

    gdisk is a command line program, you use it from Terminal. This thread has numerous examples for how to create a new hybrid MBR. The one thing you need to do different is only to add partition 5 to the MBR, make it bootable, and when it asks if you want to protect more partitions, say no.

    Sorry..Im not good in English.

    Do u mean I simply following this following command?

    Write it exactly the same with this following command?

    (taken from page 1)

     

    sudo gdisk /dev/disk0 

    r <enter>        go to the recovery & transformation menu

    h <enter>        create a new hybrid MBR

    5 <enter>        add partion 5 to the MBR

    <enter> accept the default MBR hex code of 07

    y <enter>        set the bootable flag

    n <enter> do not protect more partitions

    o < enter>       print (display) the MBR

    w <enter> write partition table to disk
