Q: Bootcamp install not working after update

I have a 2015 MacbookPro 15inc with Windows 8.1 installed under bootcamp. I had an update mess up bootcamp earlier in the year, but was able to fix it using command prompt. However since updating 2 days ago bootcamp has stopped again and anything I do does not work.

 

When I boot with option key I see a mac and windows option, when I follow the windows I get an immediate blue screen with error 0xc00000e. I have tried various diskpart and bcd commands with no success, in-fact now I have two options for windows on boot, neither of which work.

 

I have looked at some of the other inputs in the forum and have posted the requested info from command below:

    Please see https://support.microsoft.com/en-us/kb/927392?wa=wsignin1.0 (this references W7, but it is the same for W8). You will need to rebuildBCD. You need to delete the old BCD as shown in the article. Do not force the MBR. It is good to see that the installation is recognized.

    Apart from C:, do you have either an X: or D: (or any other drive letter)? If C: is your USB EFI Boot, it will not have the BCD store that you want to repair.

     

    If this command is available, try the following command.

     

    wmic logicaldisk get deviceid, volumename, description

    AAs you can see from dir command c has windows install. The second screenshot is from your command.image.jpgimage.jpg

    Try the following steps.

     

    • cd c:\boot
    • attrib bcd -s -h -r
    • ren bcd bcd.old
    • bootrec /RebuildBcd

    If I look at my BCD.log file (from the OS X Terminal), I see

    cat /Volumes/BOOTCAMP/Boot/BCD.LOG

    regf?jC?,?? pDevice\HarddiskVolume4\Boot\BCD?>c?(??:½\

    @&?>c?(??:½\

    @&?>c?(??:½\

    If you ignore the binary data, the highlighted part is where it expects to be and will try to put it in the same location. In your case, previous attempts may have caused the location to be corrupted. There is no 'cat' command on your USB, but a 'more' command may work and will give you binary data, but can you look for this string in the current BCD? When the WindowsRE (GPT5) was created, you BCD is on that partition, and it is NTFS, as your dd of rdisk0s5 shows.

     

    The worst-case scenario is that you will lose the BC partition. If you can see all your files when booted via USB, do you want to copy them to an external disk, before any further attempts are made. Another option is to re-install Windows in the same location, which will copy your current installation to Windows.old.

    I have used xcopy to transfer entire c: drive to a folder on external HD, used command:

     

    xcopy c:*.* d:/win/ /e /s /c /f /k /h /g

     

    Hopefully that should have everything. Wasn't sure of a better way to copy everything - not that i necessarily want everything.

     

    Anyhow, if you have any other ideas? I'm all ears!

    Before you wipe and start over again, if possible, make another copy using xcopy, before you wipe and start over again.

     

    Since you have a 2015 Mac, you can run an EFI install, which is much cleaner and faster, and does not impose the limitations that a legacy BIOS install imposes.

    Would the original bootcamp copy not have been an efi install? If not and an EFI install is better how do we do it?!

    Yes, it should. You can check the USB for an EFI structure.

     

    1. Erase and convert disk0s5 to Free Space - diskutil eraseVolume free untitled /dev/disk0s5

    2. Erase and convert disk0s4 to Free Space - diskutil eraseVolume free untitled /dev/disk0s4

    3. This should merge both parts into a single contiguous chunk of space.

    4. Insert your BCA-created USB.

    5. Power cycle your Mac and hold Alt/Option key.

    6. Choose EFI Boot.

    7. Point to the Free Space chunk in step 3. This will create an MSR (128MB) and the remainder as NTFS.

    8. Install Windows. Install BC drivers by running setup.exe in Bootcamp Folder from the USB and check Device Manager for any unknown devices.

    9. Reboot and Test.

     

    The command you use has this help entry.

    diskutil erasevolume

    Usage:  diskutil eraseVolume format name MountPoint|DiskIdentifier|DeviceNode

    Completely erase a disk (partition or whole), laying down a new file system

    volume.  Ownership of the affected disk is required.  Format is the specific

    file system personality name (or alias) you want to erase it as (JHFS+, etc.).

    Name is the (new) volume name (subject to file system naming restrictions), or

    can be specified as %noformat% to skip initialization (to skip newfs). You

    cannot erase the boot volume.

    Example: diskutil eraseVolume JHFS+ UntitledHFS /Volumes/SomeDisk
