Hi,

I have the same problem.

I'm running OS X Yosemite on iMac Late 2009, and with Windows 7 on bootcamp. I don't have backup and would really like to avoid new installation of Windows.

I've changed partition size a long time ago and everything worked fine. After a while I installed OS X Yosemite and didn't check boot to Windows for a long time, and now that I need to I can't.

I did quick search with TestDisk and believe that I found addresses that I need, but not sure how to delete GPT#4 and not brave enough to try on my own.

Here are my screenshots:

From TestDisk:

Can anyone guide me through next steps?

How can I delete GPT#4 and recreate it with new start/end?

Is the new start/end/size 1468536832/1953523704/48498673?

Thank you!

Can you use El Capitan has deleted my bootcamp windows partition as a reference? Use 1468536832 in step 7 and +48498673 in step 8 in the first set of Gdisk steps?

Thank you for such quick reply.

I did this:

Sudo gdisk /dev/rdisk0
P (print the full list of parts)
D (delete)
4 (part 4)
N (new part)
4 (part 4)
1468536832 ( - Start offset in sectors or the start point for Bootcamp part)
+48498673 ( - Size offset, as opposed to End offset)
0700 (Windows part type)
P (print list of all parts just to see what changes will be made)
W (Write the new GPT)
Y (Yes! really write the new GPT)

And then this:

Sudo gdisk /dev/rdisk0
P (Print list of parts)
R (Recover)
O (print current Hybrid MBR)
H (chooses Hybrid)
Partitions numbers to be hybridized: 2 3 4
Y (Good for GRUB question)
N (part 2 boot flag)
N (part 3 boot flag)
Y (part 4 boot flag make NTFS bootable partition)
O (print current Hybrid MBR)
W (Write the new MBR)
Y (Yes! write the new MBR)
Reboot

But I still can not get BOOTCAMP in finder or in System Preferences -> Startup Disk

Only thing that is changed is this:

What can I do next?

Please post the output of

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0

Do you have any third-party NTFS software?

1. Do you have NTFS-3g? If a non-Apple NTFS driver controls the BC/Windows NTFS volume, it will not show up in System Preferences.

2. On older NTFS-3g versions, there is a Preferences panel where you can selectively disable the driver for specific volumes.

Was your Windows partition resized?

Power down your Mac, and power it backup and hold the Alt/Option key. Can you boot into Windows?

I did have NTFS-3g but I uninstalled it from System Preferences before I wrote to you here and did all those steps.

Should I check anywhere else?

What version of NTFS-3g did you have? Can run Disk Utility and check which driver controls the Bootcamp volume?

I'm not sure about the version.

This is what I have for BOOTCAMP in Disk Utility:

Can you test the power-cycle alt/option key method?

I've tested it.

Windows option is now showing on boot with option key pressed.

But can not start it:

You need Windows Startup Repair or use bootrec.exe - https://support.microsoft.com/en-us/kb/927392 to rebuild your BCD.

I saw that you recommended it in earlier post, but I don't have access to bootcamp file in finder.

How can I rebuild it from OS X?
