For months, my internal 1TB had been partitioned 750GB/250GB OS X 10.6/Windows 7, with no problems - I want to use Windows, I either reboot and hold Alt, then choose Windows when the menu comes up, or I go System Preferences > Startup Disk and change it to "Boot Camp".

A few days ago I shrank the 10.6 partition by 200GB using Disk Utility, then formatted the space as Mac OS Extended and installed the preview of OS X 10.7 Lion (I was invited to try it via the AppleSeed programme).

Since then, the only options I have in System Prefs > Startup Disk or when holding Alt during boot are 10.6 and 10.7 - Boot Camp seems to have vanished as a choice. If I open Disk Utility, Boot Camp is still there, still 250GB. If I browse the Boot Camp partition in OS X I can see all my Windows files, etc, it just seems to be gone as a bootable option

Help!

    Well, you changed the partition tables, you changed the partition ID of where Windows is or was. None of which is supported, and now you have more partitions so that Windows is no longer in one of the first 4. GPT, EFI, two HFS.

    I don't know how to edit the tables or if that will be successful.

    Had you put Lion on its own drive, or make the internal Lion + Windows. And often the case a new OS version you should also format the drive with the OS before loading, even if it lets you update. 10.6 changed partition tables and expanded the GUID and 10.6.6 made more changes. Moving target.

    Remove 10.7 and see if you can get it to work.

    This is one scenerio, testing a new OS, where running either the old OS (10.6) or the new one (10.7) as VMs as virtual hard drives would be nice.

    You might want to consider using Windows in a VM also, then you might have use of all three, or move things around with a 2nd hard drive (VMs can reside anywhere and used just not boot Windows directly).

    Ok, deleted the Lion partition and expanded my original OS X partition back to it's old size. Rebooted, and when I look in Disk Utility my Boot Camp partition is listed as "Mac OS X Extended (Journaled)" and it also says "this partition cannot be modified".

    Before I removed Lion, I booted into it, and noticed that System Pref > Startup Disk still showed "Boot Camp". I selected it, restarted, and got white text on a black screen saying "No bootable disk inserted".

    I've also disabled Tuxera NTFS but that hasn't helped

    I would have booted from another hard drive to run OS X and Disk Utility Repair Disk.

    Then I would have booted Windows 7 DVD to do any system repair it thought needed.

    I don't know what Lion did, I skipped that invitation.

    If you do need NTFS driver, I suggest Paragon, seems to be more reliable.

    Windows on Mac has a number of limitations. Yes, people have managed triple boot with linux like Ubuntu but not with two Windows or two Mac OS systems. Having one internal hard drive is too stifling. Maybe with two SSDs you could.

    Hi there, I was just wondering if you found a solution to your problem. I did exactly the same as you did with the same result. My Bootcamp is still on the desktop and shows as accessible drive. I can start it through Paralells fine just when I try to boot up on it via Option key it does not show up. I had that happen right after I installed 10.7 Lion. I uninstalled it and still it is a no-show. Does anyone has a solution for that?
    Thanks in advance

    I have done exactly same thing in the past, and not found a way back. Had to start all over.

    However there is a prog called rfedit which might help, but I have no knowledge or experience of it.

    For future reference iPartition enables many more on the fly partitioning and repartitioning options without messing up the Bootcamp partition, which Disk Utility always does

    I meant to say, relative to the OP objectives, that I recently used iPartition successfully to add two extra partitions to my MBP (which already had OSX and Bootcamp). One of the extra partitions is another bootable OSX volume, and the other is data.

    All done without messing the Windows boot ability.

    Just as a note, I used iPartition to create a new partition on the disk I had bootcamp on and it did the same thing the OP and others have described. Bootcamp is no longer showing when the option key is pressed during boot but does show in System Preferences.

    just installed LION OS X on my dual partioned mac book pro.

    Cannot go back in to Windows 7 anymore, also it shows my Windows partion as FAT 32 not NTFS ( I thought under leopard it partioned it as NTFS.

     

    anyway

     

    Now I cannot get back in to wondows on my macbook.  Spent an hour with apple, they have no clue.

     

    any idea ?

  • Bobby Lindsey Level 2 Level 2 (175 points)

    You can use rEFIt. It will search for any bootable drives on your system. It's not an Apple product but it works. http://refit.sourceforge.net/

    rEFIt doesn't seem to work on Lion...

  • kevincol Level 1 Level 1 (0 points)

    I have the same problem...  Can do WinClone, not supported on Lion, to get an image backup of W7 partition.  At this point, since I can get to all the data on that partition, I would be more than happy to do an image backup of it, reinstall Windows 7 to get the boot partition to work, then reimage back to that original W7 partition so that I wouldn't have to reinstall and reconfigure all my applications.
