Q: Boot Camp repair after deleting Linux Partitions

I'm running OS X 10.9.4 and Windows 7 x64 Ultimate on Parallels 8. This is on a Mid 2011 iMac with a 1TB Hard Drive.


Earlier this year I decided to update my setup to allow a triple boot with Ubuntu to familiarize myself a bit with Linux (using rEFIt. I was able to successfully boot into Mac and Linux and continue to use Parallels to use my Windows, however I was unable to boot into Windows anymore. Initially I setup Windows using the bootcamp assistant and then added parallels later. I no longer have a need for Linux so I used disk utility to remove the Linux partitions and gave the space back to OS X. I also moved the EFI folder to stop it from using rEFIt anymore. I tried again to boot into windows using the Startup Disk section in System Preferences but got the following message:


"No bootable device --- insert boot disk and press any key"


I restarted, put in my boot disk and was able get back into OS X. I have read some other posts on similar issues but it seems as if my case might be different since I deleted the Linux partitions.


Here are the results of the "gpt -r -vv show disk0" and "fdisk /dev/disk0" commands, tilde's added by me:

    Do you have a question? If so then please ask it with as much detail as possible. Try to be brief.

    I am trying to regain the ability to boot into Windows. As stated in the initial post above, I currently receive the error message "No bootable device --- insert boot disk and press any key"

    You will have to reinstall Windows. That is what the error message means.

    Thanks for the suggestion Kappy but I am actually looking to follow the steps for using GPT fdisk (gdisk) to repair it as seen in this thread. I know that re-installing windows will likely fix the problem but that is quite a bit of extra time to recover the data I currently have on the computer. I would like to recover the bootable partition without deleting it. I have also tried backing up the Windows partition using Windows 7 Backup and Restore which fails every time for no apparent reason. Due to this, I saved my most important files but it would still be a significant amount of time to recover this setup, seeing as I have quite a bit of software on there from work which is not easy to get onto this computer.

    Please post the output of

     

    1. sudo dd if=/dev/rdisk0s3 count=1 2>/dev/null | hexdump -C

    2. Your MBR has 0x'0C', not 0x'07' for MBR #3, and it needs to be flagged as bootable using

    sudo fdisk -e /dev/disk0

    setpid 3

    07

    flag 3

    w

    y

     

    3. Check if Bootcamp mounts and is visible in Finder.

    4. Check if files can be read in Finder.

    5. Check if the Bootcamp shows up in Startup disk.

     

    You do not have a Recovery HD, so you will end up with Internet Recovery when using Command+R/Command+Opt+R.

    The NTFS header is intact, so this may be easier than some other scenarios.

     

    Can you select Windows as the startup disk in System Preferences -> Startup Disk and reboot? If you see any errors, please post back here.

    I wish TM would support backing up Windows on the Mac (and Windows in general), so backup/restore would be supported and save posters some time and energy.

    After it rebooted, black screen with:

     

    error: no such partition.

    grub rescue>

     

     

     

    This is the same thing that happens if I turn the computer off and on and hold the option key to select windows.

    The GRUB has replaced your Mac's Bootmanager. In GRUB, does Windows show up as bootable partition?

    Loner T,

     

    in terminal:

     

    $ diskutil list

    /dev/disk0

       #:                       TYPE NAME                    SIZE       IDENTIFIER

       0:      GUID_partition_scheme                        *1.0 TB     disk0

       3:       Microsoft Basic Data BOOTCAMP                249.9 GB   disk0s3

     

    Then, within grub rescue:

     

    grub rescue> ls

    (hd0) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1)

     

    I am not real sure where to go from there. Grub rescue's list includes hd0,gpt3; which seems to be the Microsoft Basic Data BOOTCAMP partition. Does this mean it is bootable?

    Power cycle your Mac and hold the Alt key. If you see Windows select it and try. I am tempted to suggest removing GRUB totally and allowing Apple Bootmanager to come up. Traditional bootcamp requires the CSM BIOS layer, I have not seen an GRUB loader do that.

     

    Also, please see this... http://unix.stackexchange.com/questions/71555/boot-windows-from-grub-rescue-comm and-prompt

    When I choose Windows from the Apple Bootmanager, the same thing happens with the no such partition and into grub rescue. I have no problem at all removing GRUB. I only installed it for when I was messing with Linux and really have no use for it now. I read the article but it seems to just be saying to install Ubuntu again or boot Windows from an external source. I can do this if needed but I didn't know if this was like a permanent solution. If possible, I'd rather get it setup without the need of anything external, like I had it before. Is this possible?

    1. As a test, I suggest removing GRUB.

    2. Post the output of sudo fdisk /dev/disk0 just to confirm that the MBR looks good.

    3. Confirm that you can see the bootcamp volume in Finder and files in the volume are visible.

    4. Confirm that Bootcamp can be selected in Startup Disk.

    5. Select the Bootcamp disk, restart and test.
