Fix booting of bootcamp partition?

I recently, very stupidly, created another partion on my mac for no reason. It has now broken the bootcamp partition (It won't boot, does not show up in the option menu at boot). I cannot get it to fix using the windows installation disk or anything like that, so I was wondering what are my options to restore the bootcamp partition.
Any advice would be greatly appreciated, as I have some important stuff on there that I need to use. I don't want to back up my data and reinstall.
This is my partition layout:
(Note that I am also unable to get rid of the free space, if i drag the mac partition and press apply, it just undoes)

  • Bootcamp will no longer boot after deleting partition #3 of my new Mac Mini.  What happened?  Was it the way I tried to reclaim the HDD space for Mac?

    Here's my dilemma.  I have a new Mac Mini - a week old.  I installed Windows 7 on it using Mac's Bootcamp assistant.  I then set up and configured my Windows 7 world and everything worked fine.  No issues logging in between Lion or Win7 via the restart/option key procedure.  Well, yesterday I split my Mac HD partition one more time to create a third partition (was created as an "extra", e.g. possible future partition for another operating system).  After creating it, I then decided that I didn't really need it.  So I deleted it in Disk Utility and attempted to drag the Mac HD partition line downward so as to "fill in the gap" and reclaim the lost hardrive space.  It seemed as if I could reclaim about 1 gig or so, but I figured...oh well. 
    Well, the Mac HD partition seems to work just fine, but now I've noticed that I can't get into the Bootcamp partition anymore.  It wont boot.  If I try to verify the partition [doesn't even give me "repair" as an option), then it fails and gives me the following error message: "verify volume failed.  invalid request."  When I go to the Startup Disk option in my System Preferences section, it displays the bootcamp partition as a folder and not as a drive anymore.
    I'm assuming that I messed up some permissions or lost some vital links during my attempted resizing/reclaiming of harddrive space.  How do I fix this without having to reload either all of my Mac info or all or my Win7 info?  I'd hate to consider the last two days of my life loading this crap up a complete loss. 
    Thanks in advance!

    Thanks for checking in, BDAQua.
    Problem solved.
    In the docs that came with my Powerlogix accelerator card, I found this sentence buried:
    "If you reset the PRAM, the NVRAM code for OS9 compatibility is cleared, so you will have to boot from the Firmawre Update CD and perform this process again in order to boot in OS9."
    The "process" it's referring to is the process of setting up the NVRAM for booting into OS9 from the CD.
    Fortunately, I was able to find the disk, and it worked as expected. I can now, once again boot into OS9.
    Conclusion: My (unadvised) attempt to load Leopard on this old machine apparently reset the PRAM on the accelerator card and cleared the NVRAM code for OS9 boot. Although I did attempt to reset the NVRAM via Open Firmware, it did not reset it on the accelerator card.
    So, thank you BDAQua, for your "Ah yes" . . . that's all I needed to steer me in the right direction.
    Gratefully,

  • I'm installing windows 7 64-bit on my imac which I've done before but I get a message that the partition is GPT even after I format the bootcamp partition.  I just upgraded my hard drive to a 3tb and I'm allocating 1tb for windows. How can I fix this?

    I'm installing windows 7 64-bit on my imac which I've done before but I get a message that the partition is GPT even after I format the bootcamp partition.  I just upgraded my hard drive to a 3tb and I'm allocating 1tb for windows. How can I fix this?

    No easy fix for a few reasons:
    1) Bootcamp requires a hybrid MBR for the partition table. That is: both an MBR and a GPT partition table at the same time with the GPT one having all partitions and the MBR one having only the ones that are relevant, but at most 4 of them (including the protective partition and the Macintosh HD one). Which leads us to:
    2) The MBR part of the hybrid partition table cannot work with 3TB hard drives. MBR is limited to 2TB.
    I am working on a small EFI app that can boot Windows in EFI mode on a Mac and that would mean that you can go GPT only on your system. The progress of the app is slow due to the nature of EFI and for now requires that you do an unattended Windows install with slipstreamed graphics drivers, but we are adding VGA loading on top of EFI quite soon after the rest of the app stabilises. The status of the app is documented at:
    Win7 x64 booting natively via EFI (no bios emulation)
    Windows does actually successfully boot in EFI mode on most Macs (anything with a 64bit EFI should work), but does not have graphics support even if you load the driver due to the VGA pci registers not being set by the firmware. Furthermore, in Setup and Safe Mode, Windows uses VGA instead of GOP which is a failure by design since VGA is a BIOS standard and not really compatible without hacks with EFI. Other EFI implementations also add VGA compatibility at a high cost to the firmware complexity for the VGA cards available on the market that don't actually contain anything in their ROM except the VGA BIOS.
    My recomendations:
    1) Install on a second smaller hard-drive; or
    2) Wait for the EFI app to come out officially and use that to boot Windows Vista SP1 x64 and Windows 7 x64 (RTM and SP1) in the native EFI mode.
    3) Wait for Windows 8 which supports VGA-less booting acording to the AMD presentation at UEFI Plugfest.

  • Ran DiskUtility on Bootcamp partition, now windows cant boot

    I installed Windows 7 Ultimate on my MBPr and it was booting fine several times.
    I noticed yesterday the bootcamp partition was no longer showing System Preferences -> Startup Disk
    I could still get Windows 7 to boot if I did a restart on Mac OSX 10.7.4, held down the Option button during startup, then I was given the Bootcamp partition as a choice.
    I went back into Mac OSX, and tried running Disk Utility to verify and then repair the Boot Camp partition. It thought it found all kinds of errors and claimed to fix them. I let it very and fix the main root drive (my entire hard drive) and it claimed tor repair the boot paritions.
    Bootcamp still not showing in System Preferences -> Startup Disk
    Now Windows 7 does not boot properly, it comes up into system repair mode. And it can not restore to an earlier point in time. All the system repair options crash with memory reference errors shortly after they get started.
    I guess it is was silly to expect the Mac Disk Utility to properly repair a windows drive. But if it can't do this, the option shouldnt have been offered!
    So I guess its time to erase the Bootcamp partition and start over.  Good thing I didn't install anything important in Windows, other than all the updates.

    The option won't be there unless you added a 3rd party NTFS driver that is suppose to add NTFS write support.
    And that driver is why Windows didn't show in Startup Disk (which does happen too on its own and is totally benign)
    If you want to repair Windows, use chkdsk and/or the Windows 7 DVD you have. Not Lion DU.
    You dont' erase NTFS in DU either. you can format it in Windows 7 DVD, yes, just like you did originally.
    And when you get it running, make backup system image(s) with WinClone 3 (in OS X, to an external hard drive - not to your Mac boot volume)
    http://www.twocanoes.com/
    if you are going to use and need to write to NTFS, the only one current and work best today

  • How can I fix my bootcamp partition?

    Hi there,
    I'm a relative noob when it comes to OSX so please be gentle with me.
    I'm running an early 2011 Macbook Pro which initially had OSX Maverick with a Windows 7 Bootcamp partition. All was working perfectly and seamlessly until I enthusiastically decided to upgrade to OSX Yosemite which resulted in my Bootcamp partition disappearing. In my haste to try and fix this I looked through the apple support community questions and used fdisk to try and fix the issue.
    It initially worked and I now could see the Windows option on the boot menu but when actually trying to boot into Windows it ended up saying "Missing Operating System"
    I then tried to boot into Windows recovery using my Win7 CD in an attempt to repair the boot sector or whatever to no avail. I also started to try and repair the windows installation by installing it again and that crashed while I was working on it so now I have an "Unknown" area on my hard drive.
    Then I installed rEFIT and partition inspector to try and fix it and this it the output:
    *** Report for internal hard disk ***
    Current GPT partition table:

    Have I well and truely ruined my bootcamp and have to start from scratch? It's not the end of the world since I backed up most of my important documents and pictures etc but it took me a long time to install all the software that I require for work on my Windows partition.
    Any help or advice would be appreciated and again, please be gentle, I am a noob.
    Thanks in advance!!

    You have screwed up the original bootloader that enabled you to boot each OS properly. At best you can open Boot Camp Assistant and see if it will remove the partition, but my guess it will not. Hence, you must re-partition the drive back to one partition, OS X, then make a new Boot Camp partition. Alternatively, you can try using Camptune X for Mac | MacUpdate to manipulate, etc. the partition and restore the drive non-destructively.

  • Unable to boot up/into (win7) bootcamp partition following Mountain Lion upgrade

    Greetings to all, I hope somebody could please help me with this issue;
         A few days ago I upgraded to mountain lion, and immediately after the upgrade was completed and the system rebooted, I discovered that a new partition (Recovery-10.8) had suddenly come into existence in place of my bootcamp partition upon holding alt on boot.  My bootcamp partition does show up now after re-syncing boot tables in rEFIt, though all that happens while booting up is a missing operating system error.  I tried the win7 boot dvd, but it does not and did not see the partition; but very strangely, it referred to my computer as %1, and my account name in OS X is simply “1”.  This leads me to believe that my bootcamp partition got knocked back a spot due to the introduction of that pesky new partition, a problem all too similar to many others’ pleas for help, though too individually complex for a simple copy and paste type of a solution~ and for a lowly user like me to tackle.
    Please do help me good sirs,
    Regards,
    Royce
    P.s. bootcamp partition never showed on startup disk
    P.p.s. in disk utility it cannot be mounted, is referred to as disk0s4, and is greyed out

    I see two things. First, notice this fourth line from your GPT. It says ~73GB of disk space is not allocated to any partition, it's free space. Why?
    40          409600       1  GPT part - C12A7328-F81F-11D2-BA4B-00A0C93EC93B

    The good news is that partition 4 for Windows in the GPT and MBR have the same start - end sectors. However in the MBR no partition is marked bootable. One must be bootable and it's customary for Apple to mark the Windows partition bootable. I strongly suspect this is why Windows is not a boot option, and it's rather easy to fix.

    My suggestion is that you reclaim the missing free space before you proceed with MBR repair, but missing ~73GB of space isn't hurting anything. Try the following and report back:
    diskutil list /dev/disk0
    diskutil resizevolume /dev/disk0 limits
    Again both are read-only commands and do not alter the disk information in any way.

  • Safe Boot seems to have broken my W7 Bootcamp partition

    MacBookPro Retina
    OS X 10.8.3
    BootCamp with Win7
    Parallel's VM 8 using BootCamp Partition
    This morning I was looking at my logs, and I saw a minor odd recurring error with a Spotlight process, so I Googled it, and found that I could fix it by doing a Safe Boot.  So I shut down my running programs, and I did a  SHUTDOWN on my Parallel's Windows 7 VM (running from my BootCamp partition).  I performed the Safe Boot, OS X came up, and everything seemed fine until I tried to start a Win7 VM using Parallels.  When I did that, I got a white progress bar that said "Windows is loading files", and then the WIndows Splash screen, and then the Windows startup recovery tool.  The tool found no errors and so was unable to repair anything, so I closed everything, and rebooted into BootCamp mode, and I found the same sequence of events, but this time the startup tool said that it had repaired Windows and then it rebooted.  But again the system went into startup repair mode, but it found no errors.  Now, each time I boot to BootCamp Win7, the white progress bar is displayed, the startup recovery runs, but it finds no errors, fixes nothing, and then shuts down, only to recur again.  I can F8 into the Windows boot menu, but any choice that I make (safe mode, reovery mode, etc.) gives me the white progress bar with the "Windows is loading files" message, and then the startup recovery tool.  I can boot into OSx, and I can see all of the files on the BootCamp partition, but I can't boot to it.
    What did Safe Boot do to my Windows boot process?  How can I fix this?  Thanks.

    7 GB is on the low side, you really should have minimum 15GB.
    Repairing permissions is an important part of regular maintenance, and should always be carried out both before and after any software installation or update.
    Go to Disk Utility (this is in your Utilities Folder in your Application folder) and click on the icon of your hard disk (not the one with all the numbers).
    In First Aid, click on Repair Permissions.
    This only takes a minute or two.

    If you were having any serious problems with your Mac you might as well complete the exercise by repairing your hard disk as well. You cannot do this from the same start-up disk. Reboot from your install disk (holding down the C key). Once it opens, select your language, and then go to Disk Utility from the Utilities menu. Select your hard disk as before and click Repair.
    Once that is complete reboot again from your usual start-up disk.

    You can not create another partition on a drive containing a Boot Camp partition. You now need to erase then format your drive. Reinstall OSX then reuse Boot Camp Assistant to create a new Boot Camp partition. Reinstall Windows. Ensure you copy off all your data before erasing and formatting the drive.

  • Installing Windows 7 on my bootcamp partition (mid-2009 mac book pro with mountain lion) My computer won't boot from the Windows 7 Install DVD.

    Hello,
    I have been trying to install Windows 7 on my macbook pro (mid 2009, MBP53). I have successfully created a bootcamp partition using the assistant. When the computer tries to boot from the windows 7 install dvd, the screen is just black. The dvd spins for a bit, then stops and the computer is just black (no blinking cursor).
    Any advice would be very appreciated.
    Thanks.

    What kind of an install DVD are you using for Windows?
    You can use any DVDs that are hardware specific. Only the full non-hardware soecific DVDs work on the Mac.

  • Bootcamp partition won't boot with two OSX installations

    Hey,
    I have a MacBook Pro running OSX Mavericks (10.9.5) and had installed Windows 8.1 through Bootcamp and everything worked like a charm. I then added a new partition to install the developer preview of OSX Yosemite. Everything worked, I could boot to OSX 10.9.5, OSX 10.10, both recovery partitions and Windows.
    Lately, my Mac had some issues that made me booting to 10.9.5 recovery and using disk utility to repair the Mavericks and Yosemite partitions (both were good, interestingly I could not repair the disk permissions, though) and I even clicked on "Repair", as the whole disk was selected and Disk Utility repaired something (I forgot what it was, but I think it changed the MBR).
    Now the Windows partition is gone, when I option-Boot and when I try to reboot from OSX to the Windows partition using the "startup disk" option of System Settings, it says
    No bootable device --- insert boot disk and press any key
    I want to be able to boot Windows again (and my OSX partitions) and would love to be able to do so, even when I choose to delete the Yosemite partition once it's out of beta so that I can update Mavericks. I tried using this guide:
    Repairing Boot Camp after creating new partition
    My problem is that it says that the Windows partition should be number 5 on /dev/disk0. In my case, the described partition is number 6.
    Can I simply replace the number and it should still work or will it break something that the Windows partition is not at the place it normally is?
    Thanks in advance

    Well, I just tried it and it didn't work. I still don't see the Bootcamp partition when I option-boot and when I try starting Windows via Startup Disk settings, the screen just turns black after a while and then a white blinking horizontal cursor appears (not even the "No bootable device" error any longer).
    Any help would be appreciated.

  • Boot Camp "Quit and install later" corrupted the BOOTCAMP partition

    I just had my new iMac delivered.
    The first things I did was to run Software Update to install 10.6.8, then I installed 10.7.1 Lion and ran Software Update again just to be sure I got everything up to date as it should be. After installing a couple of applications via App Store and the web I set about to create a Boot Camp partition for my Win7 needs. When the assistant was finished (a new partition created and drivers saved to a USB memory stick) and told me it was ready to install Windows, but I choose Quit and install later (and oh, what I now regret that choice) because my Windows DVD was nowhere to be found (I should have looked a little harder).
    Then when I later found the Windows 7 install DVD I launched Boot Camp Assistant again, but lo and behold when it tells me that I need to reformat my partions and start over from scratch. Boot Camp Assistant refuses to let me install Windows because I choose Quit and install later.
    I have tried the following things to solve the problems:
    Repair permissions and repairing the disk.
    Start with the bundled OSX DVD to run fsck -fy followed by Disk Utility.
    Re-format the BOOTCAMP partition.
    Boot from the Windows 7 DVD (which claims something along the lines that the partition does not support Windows installations).
    Nothing works! Why? How do I solve this?

    The past and having used whatever. FWB HDToolkit, Silverlining, $10K worth of scsi means??
    windows requires that the partition table and format (GUID) has full functional MBR that Windows and Mac can work with.
    Ever heard of take your best guess and double it for how much space to allocate? or no matter how good your partitions will always need to be changed.
    Apple (that pdf guide?) is quite clear about one thing, which I usually but not here, take with grain of salt, that Boot Camp Assistant is a one trick pony to do the job of setting aside unfragmented free space for Windows.
    ie, you can't use FWB Toolkit of SoftRAID 4.0 (excellent though it is!). Though Paragon CampTune (the company is rare, supports Boot Camp etc) and can be used.
    If you created it now, but then you had 10.7 and Boot Camp 4, I could possibly get my head to imagine there could be an issue. And that is because every OS version has new changed partition table changes, making for this old (65 and going) mainframer to re-initialize drives whenever there is a change.
    You can clone your system, format, and restore nice and clean with SuperDuper in a Jiffy. So why bother now? can't see it.
    I understand people wanting 3 or more partitions. Wanting Windows to boot off external drive. Or use GPT and UEFT (that may happpen as 3TB drives and is beginning to be supported, but so far Apple and EFI are closed, proprietary, and GPT booting and EFI go hand in hand) but extra partitions is just... wishful.

  • My BOOTCAMP partition can't be mounted and can boot but will fail boot, doesn't show in shartup disks what do I do?

    Hi everybody.
    After Updating the new 2.9EFI update for the 2012 MacBook Pro, I restarted the computer which was set to boot into windows. The windows booted and show the BSOD for a brief moment then closing. After I booted into Windows again to see "BOOT FAILED!" I switched into Mac OSX to see that the the BOOTCAMP partition was also gone in finder so I opened Disk Utility to see that the drive was unmountable so I did disk repair and said everything was fine. I booted windows again and now it says a different message, something on the lines of NO OS. I don't know whats happening and everything was working fine until this EFI 2.9 UPDATE and I want to keep my OS and don't want to get rid of windows. I also wan't to keep my documents on Windows. BOOTCAMP still says I have windows installed. Nothing else recognises windows is there exept DISK UTILITY. I did not tamper with windows. I also can't delete partition... MAC OS is working fine.

  • Booting Bootcamp partion from restored Bootcamp partition

    My Boot Camp XP installation is no longer bootable after I restored from a backup I created in Disk Utility 2 days ago. The Bootcamp partition is not listed as bootable when I boot my MacBook and hold the OPTION key. When I configure my computer to boot from that partition in System Preferences, I receive a black screen with message "No bootable device"
    I installed XP in Bootcamp and it was working fine. I needed to re-format my hard drive, and I used Disk Utility to make a backup of the partition. After re-formatting my hard drive, I restored the partition from the .dmg backup images, and all files are available.
    All files are present as they were when my hard drive booted 2 days ago. I belive this is simply a matter of making the partition bootable. Can anyone help?

    After analyzing and trying things out, I was able to solve this. It seems that Boot Camp does not flag the partition as ACTIVE immedately after Boot Camp creates the new partition from windows.
    Assuming you already have a .dmg image of your previous Windows Boot Camp partition, do the following:
    :: 1
    Use Boot Camp to allocate the new space. Don't use Disk Utility because the MBR will not be configured properly
    :: 2
    Use Disk Utility to restore your .dmg image to the new Boot Camp partition you just created. Be sure to run IMAGES --> SCAN IMAGE FOR RESTORE in Disk Utility before restoring. You may need to unmount the Boot Camp partition in Disk Utility before it begins to restore.
    :: 3
    Use fdisk in Terminal to mark the Boot Camp partition active. First, enter the fdisk MBR edit mode by running the following:
       $sudo fdisk -e /dev/disk0
    Ignore the error "could not open MBR file /usr/standalone/i386/boot0: No such file or directory". Then, determine which partition number to mark active by running the following (*in bold*):
       fdisk: 1> show
    Your windows partition should be #3 labeled "Win95 FAT-32". Now, mark the partition active:
       fdisk: 1> *flag 3*
       Partition 3 marked active.
       fdisk:*1> write
       Device could not be accessed exclusively.
       A reboot will be needed for changes to take effect. OK? [n] y
       Writing MBR at offset 0.
       fdisk: 1> exit
    Now, reboot and hold the OPTION key and Windows should be listed as a bootable option.

  • When I boot holding option, both Mac and Bootcamp partitions show up, but disappear after 2 seconds.

    I recently swapped out my HDD for an SSD in my 2007 MBP. Hardware installed fine. I installed Mountain Lion from a time machine backup (of the same machine). I made the Windows partition in OSX, then installed Windows 7 on the partition it had made. In Windows, I updated Bootcamp to 3.3.
    Everything seems to work fine in both OSX and Bootcamp from what I can tell. The problem is, when I boot and hold option to choose my boot drive, both drives appear and then disappear in about 2 seconds. They disappear with a "poof" animation, as if you had dragged an app off of the dock. If I'm fast enough, I can choose the boot drive before it disappears.
    I tried once again reinstalling OSX from my last time machine backup (prior to the SSD swap), and the problem persists.
    I thought it might have something to do with NTFS 3G and MacFuse, because I'd heard that they cause a bug where the bootcamp partition won't show up under the "startup disk" preferences pane. When I uninstalled said programs, bootcamp showed up under there startup disk options, but the problem persists.
    Any ideas?

    Actually, this is just getting weirder.
    Disregard my edit above. Clicking once doesn't have any effect on the drives. But the drives disappear only coming off of a RESTART from OSX. If I Shut down fully, the problem is solved. Likewise, if the drives have disappeared after a restart and I am forced to turn off the computer by pressing the power button, upon boot up the drives no longer disappear (Regardless of any action I take).
    It would seem that the drives are disappearing due to something during the restart process.
    Okay: Here are some workflows that might shed light on the situation:
    Boot to Mac -> Shut down -> Alt boot : DOES NOT DISAPPEAR
    Boot to Mac -> Restart -> Alt boot: DISAPPEARS
    Boot to Mac -> Shut Down -> Alt boot -> Boot to Windows -> Shutdown or restart -> Alt boot : DOES NOT DISAPPEAR
    Boot to Mac -> Restart -> Alt boot & fast select -> Boot to Windows -> Shutdown or restart -> Alt boot: DISAPPEARS
    Boot to Mac -> Restart -> Alt boot & disappears -> Turn power off -> alt boot: DOES NOT DISAPPEAR
    So the core culprit is something to do with OSX restart. The method of shutdown during windows doesn't seem to matter.

  • Bootcamp Partition Wont Mount, Boot and Is not Readable

    thank you in advance to anyone who can be of support.
    I have been running parallels desktop 6.0 on my macbook pro with no issues. I was using bootcamp as my virtual machine. I was also using bootcamp independently with absolutely no problems.
    After upgrading to Lion, Parallels no longer worked and I used bootcamp exclusively. Finally i got fed up with having software that I paid for not work and tried to re-configure parallels to work. I erased all virtual machines and tried creating a new one from bootcamp. Parallels changed the name of my bootcamp partition to "disk0s4." Setup did not complete and now i have no parallels. Further, my bootcamp no longer works. I cannot even access the partition. It is greyed out on disk manager. I ran the recovery tool and tried repairing the partition and got the error: "disk utility cannot repair the disk.....reformat."
    If anyone can tell me how to get this partition working again, it would be a miracle. However, at this point, my sole concern is somehow retrieving ONE folder that was saved on my desktop in windows that has some very very important documents that were not backed up last night. If someone can help me access those files through the mac side, I would be very appreciative.
    I am running Parallels 6.0.12094. I have Mac OS X 10.7 on a MacBook Pro. Bootcamp was running 32-bit Windows 7.
    I have posted this in the parallels forum as well.  I figured someone on this forum would be more likely to adivse me as to whether I can somehow access files stored on the greyed out partition.  thanks.
    I have attached a screen shot of what disk utility states.  Note it says the drive is formatted FAT (ms-dos?)

    Will it run? Yes. You are making some assumptions. There is a thread over on Lion forum and cloning OS back and forth is fine.
    The recovery partition is optional .

    Also, Paragon makes bootable clone drives for Windows (you just can't boot from it on a Mac without it being the internal drive). But that clone requires the entire drive, not just a partition. And not sure what you had in mind. Windows Easy Transfer is for data, not apps, not for Windows OS. But be that as it may.
    Clone X 4 can do sector of an entire hard drive and all partitions. Or clone an HFS volume.
