BootCamp win7 partition gone

Like alot of other people here, i have the same issue: My windows partition is not visible and can't be booted from.

But i did not update to yosomite. I just started my mac partition (after a long time).

I can see disk0s4. I did resize the windows partition once. Im not sure if i installed a ntfs software for osx since i once looked into it, but can't remember if i actually did install it. I used the disk utility to make the mac partition smaller to get more space to my bootcamp partition a second time. But bootcamp was already gane before that. I figured it just wasn't showing.

I did a few outputs but now i don't know how to go on from here:

Bootcamp partition resizing is not supported once installed. From Boot Camp 5.1: Frequently asked questions - Apple Support

Can I resize the Windows partition after installing Windows?

No. Back up your important files, then use Boot Camp Assistant to delete the old partition and create a new one.

Can you use Bootcamp disk0s4 gone after Yosemite update as a reference and start with Testdisk?

Hey Loner T

Thank you for your answer. Now, I know that it is not a good idea. :-P

Can you use Bootcamp disk0s4 gone after Yosemite update as a reference and start with Testdisk?

Yes. But it seems i can't access the disk0 with testDisk. It says, that probably I'm not root user.

But i don't know how to change that. I'm not that experienced with OSX.

Use the "sudo" option, but you will have read-only access since you are booted from this disk. This will prompt you for your user password.

The reason you cannot see /dev/rdisk0 is because you started testdisk normally instead of using sudo testdisk /dev/rdisk0.
