Yosemite killed Win 7 bootcamp....

Similar to many others; since Yosemite update my Windows 7 boot camp is no longer there on Option key start up or Mac's Disk Utility. I have no backup for Mac OS or Windows, the main thing that's stopping me doing a nuke and pave is a lot of downloaded programs for uni on the Windows side with a lot of work saved there.

Here is my terminal output for:

diskutil list

diskutil cs list

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0

Any help and guidance on next steps would be greatly appreciated.

The NTFS header on your Mac was corrupted by Yosemite. You are in a situation similar to many others documented here - Bootcamp and Yosemite upgrade - potential data loss warning.

You will need to use Testdisk and Gdisk. Can you take a look at Yosemite Upgrade Broke Bootcamp and follow the steps? If you run into any issues, please post back. The Gap between GPT#3 and GPT#4 is where your correct NTFS header is sitting.

Ok, started through this thread Yosemite Upgrade Broke Bootcamp , and i try this

sudo fdisk -e /dev/disk0

setpid 4

07

flag 4

p

w

y

but on running the first line I get an error:

fdisk: could not open MBR file /usr/standalone/i386/boot0: No such file or directory

Enter 'help' for information

fdisk: 1>

unless that's expected of course

That is an expected error, and I always forget to mention it. 😟. Please continue.

Ok i ran that and rebooted and checked for any sign of windows (finder, start up disk) and it isn't there. Here is sudo fdisk /dev/disk0

You will need to download Testdisk and GPT Fdisk as mentioned in the linked thread Yosemite Upgrade Broke Bootcamp and start a scan for missing NTFS headers.

I reckon I can do the 4 steps before coming to you before the 5th, but which start and end do I use when making the GPT#4?

Fantastic. This is start/end/size of 391141376/625141752/234000377.

Using these, do you have the steps from the referenced thread to delete the old GPT#4 and recreate a new one?

If you look at the current GPT, you can see 391141376 is a bit below 391141288 (88 bytes). This is where Yosemite corrupted your NTFS headers. Make sure you see "System Volume Information".

Ok, steps 1-4 seem to have worked. I can now see bootcamp on desktop, finder and startup disk. but Not when i want to boot to it using alt/option key at start up.

You need to recreate the Hybrid MBR using Gdisk, after you have the correct GPT in place. That was Step 5 in the original thread.

"5. Once you a working GPT#4, a new hybrid MBR needs to be created which will overwrite what you see in your Fdisk output. This is also done using GPT Fdisk (Gdisk)."

Awesome, that seems to have worked, i can now boot into boot camp 🙂 . Like the other thread I don't have the recovery drive there though. (not a big deal)
