Q: Unable to boot up in bootcamp after installing Mountain Lion

I have a very new iMac and had Win 7 installed on Bootcamp with minimal trouble and it's been running great, had it set up so that if I just restarted it would automatically boot Windows. Awesome, I love Mac. Problem now is, I just installed Mountain Lion and not only does it not auto-boot to windows, I can't get the Dual boot screen (holsing Option after restart) at all. I've tried several times to make sure that Option is regestering upon startup, and it's all good.

 

I usually have good luck finding answers to stuff like this on the forums but I'm not seeing any cases exactly like mine yet. I would love any advice anyone can offer and I'm happy to provide any info about my system that could help.

iMac, OS X Mountain Lion, 27" 3.4 GHz Intel Core i7

    Very interesting. fdisk is reporting the 2nd MBR entry starts with a negative sector value.

     

    The first command will read sector 0 of the disk, and put it into a file in the current user home directory. The second command will dump the hex values of the file to display. Please post the results after hexdump.

     

    sudo dd if=/dev/rdisk0 of=~/mbr.bin bs=512 count=1

    hexdump -C ~/mbr.bin

     

    If you can click on "Use advanced editor" to the upper right of the forum's Reply to entry area, highlight the pasted text and change the font to Andale Mono. It will make the results easier to read.

    446 for 64? Looking at the Partition table?

    446 for 64? Sector 0 is the MBR, the first 440 bytes of which are the bootloader. The rest is the table. I see how this is being encoded and why it works, sorta. But neither Apple's fdisk nor Linux fdisk considers MBR partition 2 valid, it will not let me define it with the exact same start and end sector values as what your disk has.

     

    I think this may be extremely fragile. It might be Apple's Mountain Lion installer is doing a file system check which includes a GPT check, which by inference could include an MBR check. I wonder if they're nuking the hybrid MBR on disks that are bigger than 2TB, which some people have managed to get working with 3rd party utilities like iPartition.

     

    It might not even be Mountain Lion related, it might be a long standing behavior that's only revealing itself recently due to increasing numbers of 2+TB drives and utilities like iPartition that seemingly can deal with them.

     

    I'm still not sure whether this MBR is non-standard or not, but I'm going to look into it.

    Could you put this mbr.bin into a publicly available location like public dropbox? I'd like to apply it to a virtual disk in a VM, and see if the Snow Leopard installer nukes it.

    This iMac has been running with Bootcamp this way since I bought it.  It came with Snow Leopard on a 1TB hard drive.  I upgraded to Lion with no problems, but Mountain Lion was the one that caused the problem.  I noticed that when I initially had the issue, the MBR was called the PMBR in all of the command line queries. Interesting how that changed.  Incidently, at work we are installing 3 TB hard drives in our forensic Macs with Snow Leopard being carried over.  Bootcamp is working on them and from what I've heard the OSX has to be Snow Leopard or higher.

    This iMac has been running with Bootcamp this way since I bought it.  It came with Snow Leopard on a 1TB hard drive.  I upgraded to Lion with no problems, but Mountain Lion was the one that caused the problem.

     

    But that's with a 1TB disk. When was it migrated to a 2.5TB disk? And what was the order of the upgrade?

    2.5TB disk > Lion > Mountain Lion?

    Or Lion > 2.5TB disk > Mountain Lion?

    Or Lion > Mountain Lion > 2.5 TB disk?

     

    I noticed that when I initially had the issue, the MBR was called the PMBR in all of the command line queries. Interesting how that changed.

     

    A GPT disk has a PMBR. A PMBR is an MBR with a single partition entry, partition type 0xEE, with a start sector of 1, and end sector going to the end of the disk. It's designed to inform legacy MBR only utilities that the disk is claimed for data, as the GPT begins on sector 1, whereas the MBR is only on sector 0. An MBR only utility will only look to sector 0, meaning it would entirely miss the fact it's a GPT disk were it not for the PMBR.

     

    However, Boot Camp relies on a CSM-BIOS method of booting Windows, which requires a legacy MBR partitioning scheme, i.e. one with more than a single partition entry. These are called hybrid MBRs. They're non-standard, and notoriously flakey. They are not consistent with the UEFI spec, there's no correct way to make one that ensures stability or consistent interpretation from OS to OS, and even Apple's own developer notes say once a disk has a hybrid MBR it is not a valid GPT disk anymore and should not be subsequently altered in any way or data loss can occur.

     

    In a 32-bit MBR world, a disk larger than 2TB is probably invalid, and different OS's and tools react wildly differently when this is forced beyond 2TB. Apple's own fdsik tool refuses to cooperate with > 2TB disks at all, and Red Hat Enterprise Linux's fdisk effectively says not to use fdisk because such a disk requires GPT, and Microsoft's tech notes on this say if you want to use a 2+TB disk as a boot disk, it requires GPT which means EFI boot is required. So I think you're in a doubly fragile situation using not only hybrid MBR, but also one that take advantage of a quirk of MBRs that allows the creation of a partition beyond 2TB.

     

    Incidently, at work we are installing 3 TB hard drives in our forensic Macs with Snow Leopard being carried over.  Bootcamp is working on them and from what I've heard the OSX has to be Snow Leopard or higher.

     

    I think going beyond 2TB with Boot Camp should be discouraged for all the reasons I mention above. I'm honestly surprised that Boot Camp Assistant will even work on a disk larger than 2TB for this reason. The last time I tried it with Boot Camp Assistant it refused to work with disks of this size.

    Ok, 1TB drive Snow Leopard upgrade to Lion then drive upgrade using Winclone to copy and restore Bootcamp to the 2.5 TB drive then the Mountain Lion upgrade.  I looked at a lot of posts that people had success with but again, the only thing that made Bootcamp boot seems to be iPartition.  It could be added support for NTFS in the OS or I just got lucky.  Even so its working and I will continue to keep current backups of my data just in case.  I know if you try to use the Bootcamp Assistant, it allows you to create the partition size, then asks for the windows disk to complete the partition.  On reboot it starts the install but fails because the Bootcamp partition is GPT when in reality BCA formated it as FAT.  If you do the advanced and format the drive, it removes the Bootcamp name, but formats to NTFS.  I had quite a few trial and error times but the process that worked for me was what I listed in the first response post.  Possibly the answer lies in Winclone and what its doing during the backup and restore process as it asks if you wish to rewrite the Bootcamp BCD.  Look here: http://twocanoes.com/support/winclone/migrating-a-bootcamp-partition-with-winclo ne  This may be the clue to how its working.  I will soon be upgrading my work machine with three 3 TB drives.  One of my current 1TB drives is dedicated to Bootcamp.  It will be interesting to see how the transition will be to the new drive.

    Can anyone confirm/deny that Boot Camp Assistant 4.0.3, or higher, disallows resizing/partitioning a disk larger than 2TB?

     

    For sure, Disk Utility will refuse to MBR format a disk larger than 2TB. I wonder if in the course of Mountain Lion checking/repairing a disk before install, if it's nuking hybrid MBRs on disks larger than 2TB. Such an MBR is really not a good idea.

    OK so I can confirm with Snow Leopard's Disk Utility, if you reformat/erase a volume, a hybrid MBR is obliterated back into a PMBR and thus Windnows is unbootable. Despite the fact you're not repartitioning, merely formatting a partition, it appears the GPT and MBR are rewritten. Any hybrid MBR is replaced with a PMBR.

     

    Correction: This only happens on disks larger than 2TB. The hybrid MBR remains intact on disks 2TB and under.

    And at least the Snow Leopard installer isn't replacing hybrid MBRs with PMBRs on any sized disk. However, erasing the target volume first, on a disk larger than 2TB, will cause the hybrid MBR to be replaced with a PMBR.

    Hi Chistopher!

     

    I upgraded to Mountain Lion from a Lion install. It had a Windows 7 64-bit partition, but now it doesn't show up after upgrade. Even diskutility doesn't recognize the partition!!! It just names it "disk0s4", not BOOTCAMP.

     

    I ran the commands you've put here earlier and the results are as follows (quite bad from what i've read...):

    mouse:~ rramalho$

     

    The MBR partition table is empty!! Help... I also have rEFIt installed. Is this a problem? I haven't ran the GPT/MBR sync thing...

     

    Can i recover my files and/or partition? I think i have lost 2-3 days of work here

     

    Thanks!!!!!

    409640      1070312512      2  GPT part - 48465300-0000-11AA-AA11-00306543ECAC
    1071992832   393154560      4  GPT part - 48465300-0000-11AA-AA11-00306543ECAC
    

     

     

    Partitions 2 and 4 (disk0s2, disk0s4) have partition type GUIDS for HFS+. Did you inadvertently erase one or both partitions before you did the upgrade, because that's what it looks like has happened.

     

    Now, there's some small chance the partition type GUID is wrong, and there actually is still an NTFS system starting at LBA 1071992832. To find out:

     

     

    sudo dd if=/dev/disk0 of=~/disk0s4_4s.bin skip=1071992832 bs=512 count=4

     

    Note! The above command scrolls off to the right and ends with the number 4, you just can't see it. I suggested you copy-paste. If you don't include count=4 at the end it will not end well... (i.e. it'll start filling up your drive until totally full). It should take less than a second for this command to execute, so if you aren't immediately dropped to a prompt, you can cancel with control-c.

     

    hexdump -C ~/disk0s4_4s.bin

     

    The first command will read the first four sectors starting at LBA 1071992832 and write them to the file disk0s4_4s.bin located in your user home directory. The second command will read the contents of that .bin file and display them. Every file system as a header somewhere in the first four sectors of the partition, so if it's NTFS and not HFS+, merely changing the partition type GUID in the GPT, and restoring the hybrid MBR will fix the problem. However, I'd say there's a 99% chance that this partition was erased (i.e. formatted) as HFS+.

    Well...

     

    I did *not* format the NTFS partition! Something went bad... really bad in the process...

    mouse:~ rramalho$

     

    Do I still have a chance of recovering my stuff? I guess so by the look of the dump. It has all the normal windows stuff in there...


    How do I change the partition type ID do NTFS on a Mac? And how do I sync the GPT/MBR thing?

     

    Thanks! You're *the* man!
