    Ok, that sounds like the best plan!

     

    With regard to getting rid of my current Bootcamp partition, what is the safest way of doing this? Just using Bootcamp assistant? I didn't know if the changes made using gdisk might influence this.. so wanted to ask first just so i'm 100% safe!

  • Loner T Level 6 Level 6 (8,985 points)

    You need to delete the Windows partition using the Boot Camp Assistant, and start over to change the size of the Windows partition.

    Ok, thanks Loner T!

     

    I'm making a WinClone image of my working-Windows partition now - the one on the external drive.

     

    Then on my main drive (the problem-drive), I'll use bootcamp assistant to remove the faulty windows partition, and hopefully restore the full 512Gb to OS X. I'm a little worried there's gonna be some free space that get's lost... but let's see how it goes.

     

    With the 512Gb of OS X, I can then re-make a windows partition - but i'll do this manually via Disk Utility. I'll make a 101Gb MS-DOS (FAT32) partition. The WinClone image I will be restoring from is 101Gb.

     

    Finally, fingers crossed, I'll use my external drive to run WinClone, and restore the image i've made to that FAT32 parition.

     

    I'll let you know how this goes. If you recommend any changes to this process, let me know!

    If you delete the Bootcamp partition, the OSX SSD can be converted to a single partition scheme, till you are ready to re-partition for Winclone.

     

    Your steps match this - https://www.twocanoes.com/winclone/support/create-a-boot-camp-partition and other FAQs.

  • jordan_ellipsis Level 1 Level 1 (0 points)

    Sucess! It worked! Thanks so much for your help Loner T!

     

    A small note for anyone else attempting this: my first attempt to restore the Winclone image didn't work. The program just sat there idle, when it was supposed to be restoring. I found out it was because my destination partition was slightly too small (well, it was the exact same size as the Clone image, 101Gb). I increased my partition to something like 110Gb, and tried again. It worked!

     

    So although I wasn't able to resolve the initial problem (to which this thread is dedicated), I at least now have a bootable windows partition again, and I can copy over my backed-up files.

     

    Thanks again!

    Hi T,

     

    I can now boot from both windows and OSX after re-create the hybrid MBR. However, i find that i cannot read the Mac and FAT(formatted in osx) partition any more in windows even with bootcamp tool. Both partitions are marked as GPT Protective Partition. Is this expected? If there any method the make it readable again?

    here is the screen

    Thanks.

    Can you provide the output of

    sudo fdisk /dev/disk2

     

    There is a read-only HFS driver which is installed as part of Bootcamp drivers. Here is what I have in BootCamp.xml. You should not change the drive letters assigned to the drives, otherwise it causes excruciatingly painful issues.

    Can you check your Windows Registry for the Registry keys referenced? Please do not modify the Registry, unless you really need to.

    I'm also having trouble with BootCamp, the option to boot into Windows is gone. I can see the partition in Disk Utility and can navigate/copy the files from the Bootcamp partition through Finder.

    Looks like the partitions were resized in Disk Utility to leave this "hole".

     

    Your MBR needs to be corrected as the first step. Please see this link - https://discussions.apple.com/message/22253524#22253524

     

    You may also need Windows Repair after this is done.

  • .preatorian. Level 1 Level 1 (0 points)

    Yes, that is correct. I was having an issue with the system and the Apple tech instructed me to make a "test" partition. You would think the Apple support staff would know the result of adding a partition when Bootcamp is used, I learned the hard way.

    I followed the steps in the article and that seemed to repair the MBR, and Windows will now boot.

     

    I tried to fully expand the Mac partition, but it never finishes the process and I am left with this:

    Is there something else that needs to be fixed?

  • Csound1 Level 8 Level 8 (43,355 points)

    Erase the drive (backup first) then reinstall OSX,

  • Loner T Level 6 Level 6 (8,985 points)

    Another option is to Winclone the Bootcamp, convert the SSD to a single-partition in Disk Utility by deleting bootcamp using Boot Camp Asistant, and restoring via Winclone. Without Winclone, it is installing Windows from scratch.

    That's not a method I would use, but YMMV

  • BobTheFisherman Level 6 Level 6 (11,195 points)

    I wouldn't do it that way either. I'd reinstall Windows thereby removing any potential issues because of a bad initial install, etc. Just reinstall to be safe.

  • Maromme Level 1 Level 1 (0 points)

    Hello,

    Could I get some help to recover my bootcamp volume (doesn't mount on macos 10.8.5) ?

    I've created a new partition to clone 10.8.5 and upgrade to 10.9 (so 5 partitions now with recover for 10.8 and 10.9 and windows7).

    After that, I lost bootcamp boot possibility.

    Reading this topic, I managed to recover windows7 boot. Everything's fine with it.

    The remaining issue is that bootcamp volume doesn't mount anymore on MacOs session.

    Here are some infos:
