    Hi Chris


    If you have a wish to could you advise on this thread?


    I have asked this before of you, Thanks.

    Your disk, disk0, has five partitions. This isn't supported for Boot Camp disks. You can only have four: EFI System partition, OS X, Recovery HD, BOOTCAMP. You have an extra partition, apparently labeled Data.


    There is a distinctly non-standard, not highly advised, work around that will let you at least boot Windows, and also share one of the other partitions. You'll need to use gdisk to create a new hybrid MBR from the recovery menu, and add partitions 4 and 5. So you'll type 4<space>5<enter> into the proper field when prompted what partitions you want to add. This will allow you to see the partitions Data and BOOTCAMP from within Windows (and OS X also, of course). But you will not be able to see the primary Macintosh HD from within Windows. Make sure when asked that you do not set GPT partition #4 (MBR partition #2) as bootable. But do make GPT partition #5 (MBR partition #3) bootable. Then use the w command to write out the new partition tables and reboot.

    Hi Chris,


    Perhaps a bit off-topic, but I found out that:


    1. Paragon NTFS for MAC 10.0 is killing the WIN8 startup option in system preferences in OSX 10.8.2!

    2. Paragon HFS+ for Windows 10.0 gives a BSOD for HFSSYS in WIN8!


    I assumed that the cause of the startup option in OSX was a MBR mix-up but it was not. Contacting Paragon to look into the matter!


    Keep you posted! Cheers

    That is common, common with any 3rd party NTFS converter on a Mac.

    Thanks alot Christopher! Good help!

    Well I'm out of ideas. [...|

    The only tools I know that are designed to resize file systems on disks containing hybrid MBRs are Wincone, iPartition, and Camptune. [...]

    I think this particular case, copying an instance of Windows to another disk (partition) while resizing in the process, is maybe more the realm of Winclone. [...]

    A pity it didn't work out with the conventional command line tools, I'd like to thank you in any case for your help and your patience!

    And finally your last hint was perfect. This is not at all meant as an advertisement more sharing the knowledge of fixing a problem: finally Winclone did its job very well!


    Thanks and best regards,



    PS: Actually the partition table finally changed to this...not sure what I can conclude out of this:

    This sounds like a Windows 8 Fast Boot induced corruption when used with other OS's. I think you need to disable Fast Boot, but I really don't know anything more about it. You've got to realize Windows 8 isn't supported by Apple, and it wouldn't surprise me if Paragon were to say they aren't supporting NTFS file systems written on by Windows 8 either. So you should confirm that before risking your data, unless of course you don't really care about it.

    Hi Chris,


    Thansk for your prompt reply! I purchased both Paragon NTFS / HFS+ because they were adverticed as Windows 8 / OSX 10.8.2 COMPATIBLE! As far as I can determin now this is not the case!


    Windows gives me a BSOD on the HFSSYS and OSX ML won't boot properly anymore! Very disappointed in both products and even more so, because a post on the Wilders Forum, monitored by Paragon was not ever answered!


    If this was twitter I'd shout out loud #FAIL!!!!!!!!!!!!


    But never the less I'm enjoying my evening! ;-)



  • Berend de Meyer Level 1 Level 1 (10 points)

    Thnx, preparing to UNINSTALL both Paragon 'drivers'!


    The only they do is DRIVE ME NUTS! ;-)



  • Christopher Murphy Level 3 Level 3 (555 points)

    Paragon's web site says HFS for Windows supports Windows 8.


    But their notes for NTFS for Mac OS X doesn't list Windows 8 modified NTFS file systems, and so far I haven't seen anywhere on their web site an advertisement that it does. So I don't understand why you'd give them the fail whale when you're using an OS that as yet is unsupported by Apple. Quite honestly I think it's dangerous to use Windows 8, dual boot, on a computer contain data you care about at all. If it's a test machine, and the data doesn't matter, then great, go ahead and play with matches.

  • Berend de Meyer Level 1 Level 1 (10 points)

    Correct, but the NTFS for OS X ML kills the option in sys-prefs to boot from Windows 8 startup disk

    So for now uninstalled both and being a happy MACCER/WINNER again.


    It's not a 'play' machine but I make backups on a hourly/daily basis, so no worry about the data!

    Better safe then sorry!

  • Berend de Meyer Level 1 Level 1 (10 points)

    Happy to see BC startup again and booting just fine in OS X!


    Installed the trial-version of MacDrive UK! Now even I can read/write from/to my MAC_RAID0 (3TB) in Windows 8!

    Hi Chris,


    Sorry for not responding earlier to thank you for your advice.


    I decided to forego all the mucking around and simply(!) install a second drive in my Mac mini.  This is now done, and I'd appreciate your advice on how to set it up to dual-boot Windows 7 and an encrypted Mountain Lion partition - if that's even possible.  If it is, I'm suspecting it may be best to create the whole thing manually in gdisk.


    If you feel you can spare the time, I've got a thread here.


    Many, many thanks for your continued responses to this thread.

    Chris: I have also got a problem on resizing my data here:



    If you would help I would greatly appreciate it.

  • Myshho Level 1 Level 1 (0 points)

    Dear Christopher,


    after some time when I did not find backup company in my region I found the courage to use dd and make image of my harddrive and then I used your suggestion TestDisk. This application found the lost "D:" partition on BootCamp and it was possible to copy all my data.


    I would like to thank you. I was very worry about my data and your suggestion saved everything.


    Thank you again for your help!


    Best regards
