    So at that point Windows was still a boot option in the boot menu?

    It may be that Windows is hosed anyway. It would probably need a chkdsk running anyway.

     

    As I see it you could go through a whole lot of work recovering the original Windows partition with testdisk and creating a new hybrid MBR with gdisk using those older start and end sectors and Windows might still not boot.

     

    I'd be more concerned with saving OSX than Windows - which in itself may not work.

    I'm sure that disk utility won't allow you to delete the Windows partition now.

    That *may* be possible with gdisk and a new protective MBR could be created with gdisk. If that works then OSX could be saved.

    Otherwise it will mean formatting the disk and re-installing everything.

     

    Sorry it's not better news.

     

    What do you think Loner T?

    Ugh. Please have better news T Loner :|

    1. If OS X boots correctly, AND, the Bootcamp volume is visible, one option is to extract the data from the read-only NTFS side and delete the windows partition completely.

     

    2. Since Recovery is intact, OS X can be reinstalled after turning the entire disk into one partition. Worst case an erase and  format and OS X re-installation, followed by a new bootcamp installation, and then restoring files as necessary to windows from the saved NTFS (preferably to an external drive).

     

    3. The assumption in 2 is that no OS files, but only user files need to be restored.

     

    4. Testdisk is a very time-consuming, but viable option.

     

    PS: Not sure how much can be saved from step 1, especially based on locations of files on the disk.

    Well I don't know anything about testdisk or how to use it, and I don't expect anyone to devote their time to walking me through all that.

     

    I don't have a physical copy of OSX at the moment. Is there a tool in OSX to create a recovery disc so I can reformat?

  • Loner T Level 5 Level 5 (5,590 points)

    1. In this thread, there are examples of testdisk.

     

    2. If you are on ML or Mavericks, you can do internet recovery without any media. Lion can also be recovered, possibly using Target Disk Mode if there is another available MAC and Firewire and/or Thunderbolt connectivity is possible.

     

    What version of OS X do you have on the machine, StayColdb?

    What Mac are you on?

    Is there no Recovery HD in the Alt + boot menu?

     

    As you have little to lose we could try using gdisk in an effort to save OSX. No guarantee as this is something I thought up myself.

    There should be, since the GPT and MBR both agree on Apple Boot/Recovery HD.

    I have 10.9 Mavericks. And Yes 88, there is a recovery partition installed.

  • staycoldb Level 1 Level 1 (0 points)

    so I can just boot to the recovery partition and reformat that way?

    Then you can do a Command+R and start a recovery (local or Internet-based).

    A recent Time Capsule backup would be even better.

  • Number88 Level 3 Level 3 (750 points)

    Good point Loner T 

     

    So normally in these situations the only official way to deal with this is to format the drive and re-install everything.

    Obviously OSX still boots but I'm assuming that disk utility will refuse to allow you to delete the Bootcamp partition.

    Therein lies the problem.

    Have a go at that first.

     

    If it doesn't there may be a way to delete the partition with gdisk and to create a new protective MBR.

    This may fool OSX into thinking that there was never a Windows installation and it may then allow you to stretch the Macintosh HD back to the full size of the disk again.

    Thereby allowing you to start again.

     

    As I say this is not official and I haven't tried it before but it may work.

    Thanks for all the help guys. I don't really care about losing OSX because I haven't done much in it. But I spent 3 days configuring windows so I'm not excited about losing that at all.

     

    So, you guys think my best option is to just go ahead and reformat?

  • Number88 Level 3 Level 3 (750 points)

    See what Loner T thinks too, but I think it's likely that Windows is gone already.

     

    As you're thinking of reformatting anyway I'd try gdisk first. It would save some time if OSX doesn't need re-installing. But the decision is yours.

    (But I'd love to know if my idea works or not )

    Another thing: I've got some movies on this hdd I want to back up before I reformat. I was trying to transfer them over to another hdd I have plugged into a usb port with an adapter but it wont let me drag and drop the movies over. Is this because the file system of the other hdd is ntfs?
