    Have you installed the Apple Windows drivers? (Notice filesystem types are HFS. I also have an external Firewire encolsure with additional HFS file systems that you can see).

    To start from scratch, delete the Windows 7 partition from Bootcamp Assistant, then recreate a new Window volume using Bootcamp Assistant also.

    Adding a third partition will break Boot Camp. Delete it and use an external drive for data storage.

    I have your exact setup.

    Just data should be in middle.

     

    I have this setup since mid of 2011 and works perfect

    - Mac

    - Data

    - Windows

     

    From what i understand, third partition can only be in middle, if i make it at end, my setup does not work.

    So i made it in middle and i am doing great since then.

    Hi

    I installed everything from scratch,I mean by everything, the win 7. and it works now prperly. I want now to upgrade my mac to mavericks from 10.7.5 lion because I want to install latest version of x-code. Will I have again any problem in booting win 7, if I do this upgrade?

    thanks

  • Loner T Level 1 Level 1 (20 points)

    You should not. Post your diskutil list, gpt/gdisk and fdisk. You may also want to verify that your Recovery HD works correctly using CMD+R. Take a full backup of OSX and Bootcamp.

  • autnagrag Level 1 Level 1 (45 points)

    Hi. I upgraded to Mavericks, and it broke my BootCamp. I have been using FileVault2 and Mtn. Lion before the upgrade. I can see my Windows partition, and I can select it from Startup Manager, but I can't boot into it. Similarly, I can choose it in System Preferences>Startup Disk, but booting to it does not succeed.

    OK but did you create a new partition right before the failure to boot Windows? If not it seems you have a sufficient different problem to warrant a new thread. So I'd post all this information in a new thread, but also be really clear what exactly was done in between Windows working and not working, and also when you say "doesn't succeed" state what does happen, i.e. exactly how does it fail.

     

    And then also post the URL for the new thread as a reply to this one.

    You have Bootcamp on a drive which is part of a Fusion Drive. Is this an Apple-supported or DIY Fusion drive?

     

    Mavericks has a newer version of Bootcamp (5.1).

     

    If the 28GB partition can be seen as bootable in System Preferences, do you see a blinking cursor in top left corner and does it just sit there after you select it and the Mac reboots?

     

    http://support.apple.com/kb/HT5446 and http://support.apple.com/kb/HT5828 may be worth looking at.

     

    What version of ML did you upgrade from, to Mavericks?

    I would like to convert my OS X 10.7.5 partition to GPT in order to install Mavericks, so that i can get better OpenGL support.

     

    But I'm too confused and scared to do anything here

     

    What should i do?

    Please try sudo gpt -r -vv show /dev/rdisk0 .

     

    Does your Bootcamp work? (the fourth partition, id '07').

     

    Try option 2 for sudo gdisk /dev/disk0 .

     

    You may end up using testdisk (http://www.cgsecurity.org/wiki/TestDisk) and looking for partitions.

    Dec 11, 2013 4:25 PM (in response to Ulrik N)

    I'm confused by what you've posted. You have one fdisk command but you've posted two different MBRs. One MBR with all four entries full, and one MBR with only one entry. They have different values also. So I don't understand that and it seems something is missing possibly another disk.

     

    The gpt command shows there's GPT corruption. There is no such thing, normally, as converting to GPT on a Mac. It's already GPT. But yours is corrupt and that does need to be fixed before you proceed.

     

    The message "Warning: Devices opened with shared lock will not have their partition table automatically reloaded!" means you need to redo the command as:

     

    sudo gdisk /dev/rdisk0

     

    (And some people have the reverse problem, where they get the warning with rdisk0, so they need to try with disk0.)
