How can I recover files from Bootcamp?

Please ignore my last message - it was to the other poster.

gdisk is available here

http://sourceforge.net/projects/gptfdisk/

Open a terminal and run

sudo gdisk /dev/disk0

type p and hit enter and you should see your 4 partitions appear.

If so, type t and enter

it will ask for partition number - type 4 and hit enter

it will ask for Hex code or GUID - enter 0700 and hit enter

type w and enter then confirm with y and enter.

Once done type q and enter and close the terminal window.

Reboot and see.

Sadly it may be beyond repair (or at least beyond my limited knowledge).

It could possibly be worth trying the command prompt from the Windows installation/repair disc/usb and run

bootrec /scanos to see if the Windows installation is found. You could even run a chkdsk on it if it is found.

Should it be found (though it may well not be) there could be other repair options available.

Failing the above if the partition won't mount I don't know of a way of getting your files back other than the use of something like testdisk, which is a free partition recovery utility. That may be worth a try.

Once you've done what you can with it I would delete the Windows partition and let Disk Utility resize the OSX partition back to its full size then reboot.

You can then start again using bootcamp to re-install Windows 7.

Sorry, forgot to say that once a Boot Camp partition is set up you should not resize any partition on the drive at all as this will break bootcamp.

It can be used to recover whole partitions, fix partition tables or photorec can recover files.

There's a how-to page here

http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step

Basically you do a search for previous partitions and if it finds any they may be able to be recovered completely or, if not, photorec can recover files.

If you do some googling you may be able to find other peoples experiences of using it (in case the above link is a bit vague for you).

Hello

You appear to have some free space in between your recovery HD and your Windows partition. Did you try to re-size a partition after installing Windows in Bootcamp?

Thanks for your response.

yes I did resize my partitions after installing bootcamp bit it worked fine until I did this mavericks update.

I'm sure it did. However this is unsupported whilst a Bootcamp partition is there.

What's happened now is that the OSX upgrade installer has found a hybrid MBR with a non-standard disc formation and panicked. It's over-written the MBR and as a consequence your Windows partition is not now marked as bootable and I suspect the partition type has been changed from 07 to 0C.

Which version of Windows is installed?

What is in the free space I mentioned earlier? And is that free space to remain?

windows 8 was installed. It was in the larger partition (about 20 gig). If I could at least retrive my files in windows that would be great.

It may be possible to get your Windows system booting again rather than go down the route of recovering files.

What I would suggest is to download and install gdisk from

http://sourceforge.net/projects/gptfdisk/files/gptfdisk/0.8.8/gdisk-binaries/

you want the .pkg file, not the Windows one. Install whilst in OSX and to use the program open a terminal and type

sudo gdisk /dev/disk0

then enter your password. You will get an output in the terminal.

What you need to do is create a new hybrid MBR with correct details in it.

Type r and press enter, to get to the recovery/transformation menu

Type h and press enter to start creating a new hybrid MBR

You will be asked to type from 1 to 3 partition numbers. On yours you need to type

2 3 4

That's 2 space 3 space 4

then press enter

You will then see be asked if you want to place EFI GPT partition first in the MBR

answer Y then enter

Then an entry for partition 2 will appear

press enter at the default setting

It will ask if you want to set the bootable flag - answer N press enter

Next is the entry for partition 3

again accept default settings and answer N to setting the bootable flag

Next is partition 4 - this is a little different.

If the default setting for partition type is 0C just type in 07 (that's zero 7) and press enter (if the default is already 07 just press enter)

When asked if you want to set bootable flag answer Y for yes, then press enter.

When that's finished it will go back to the original prompt

type w (to write the changes) and press enter

You will see a warning that changes are going to be made - answer Y, press enter

type exit to exit then close terminal window and reboot.

Hold the Alt key whilst rebooting and hopefully Windows boot option will appear. Choose that and see if it boots.

If all goes well I would suggest you backup everything you need from Windows then remove your Windows installation through Bootcamp assistant then after a reboot start a fresh installation of Windows again through Bootcamp. Otherwise this is likely to happen again.

Once Windows is installed in a Bootcamp partition do NOT try re-sizing or creating any partitions.

Good luck!

Thanks for the detailed instructions. I have followed them .Now I am being able to see windows as a boot option but when I select it, it says' no os found'

Should i attempt to do a windows repair with the CD or is there another way to retrieve my files in windows ? thanks
