Windows 7 bootcamp partition not bootable after updating to 10.10.3

Loner T,

I've been away for a while and now I'm back to get this thing working again.

If I posted something you know won't work, I apologize. It was the only thing I had to work with the last time this happened so I used it.

If you want me to, I'll start a new thread starting off with the output of the first three commands to avoid confusion.

I need your help because a preliminary running of those commands is showing some crap that I probably created the last time I did this.

For instance:

Or am I just not using the right selections? I went back to the image you posted of how to answer the questions and I swear I followed it.

Thanks,

Jeff

1. Can you post the current state of the GPT?

sudo gpt -vv -r show /dev/disk0

2. Go to each MS Data and use the 'p' command and list files. Check if you get a reasonable set of Windows files and try to match with the sample in this discussion.

Here is the current state of GPT:

The first MS Data listing gives this when I use the "p" command:

The second one gives this which is what I think we're looking for:

Are we ok so far?

Yes, we are OK so far. GPT5 seems to be correct and matches your last Testdisk output.

From your GPT, you have EFI, OS X (CS), Apple Boot, HFS+, Bootcamp, OS X(CS - ?), Apple Boot. It seems to be a 3TB HDD.

Can you post the output of

sudo fdisk /dev/disk0

Loner T,

This is the output I'm not feeling too good about. I don't think it matches anything I've seen but I easily could be mistaken.

Yes, it is a 3 TB HDD; the question mark may be the eDrive that Tech Tool Pro 7 set up before it made my Windows partition unbootable last year-LOL!

Thanks again for your help!

Jeff

It would be good to see the output of the following commands.

diskutil list

diskutil cs list

We will need to create a custom MBR.

Here you go:

Jeff

You have two versions of OS X (and corresponding Recovery HDs) along with a Bootcamp partition. This is a very fragile setup and causes problems for Bootcamp. It may be better to install one of the OS X versions on an external disk, leaving the internal disk with OS X and Bootcamp, only.

Will that work for you?

I don't have an external drive to load anything to.

The partition table may be saying I have that 1.9 TB and another 800 GB both of OSX but I can assure you when I boot up and log into the OSX that does show up in the boot selections from the Option key when starting the machine, it shows the full 2.7 TB under that Macintosh HD.

What would happen if we just ignored the 800 GB OSX partition and worked from the goal of just getting the Bootcamp partition to be able to boot with the existing 1.9 TB OSX partition?

Is there any way to cleanup the partition table so OSX and Bootcamp are both bootable again?

In the worst case scenario, could I just use the Bootcamp utility to wipe out the windows system? I don't want to and I won't reinstall it but I'd still like to keep it if I could. Right now, it's basically a Steam gaming system for games not available on the mac and Steam.

Both versions of OS X should already be fully bootable. If they are not let me know.

The new MBR needs to consider which OS X partitions do you want to see. Can the eDrive be removed?

Is the eDrive the thing that's showing up as the other OSX system? It is bootable now but I could just as easily do without it. I'll uninstall TT Pro if need be.

I just want to be able to get back my windows and be able to boot either windows or mac osx from the option key.

Can we do this and will this clean up my partition table or is slicking it the only way to do that?

GPT 2+3 is one OS X installation.

GPT 6+7 is the other OS X installation.

Check if the eDrive can be removed using the TT tools?

I see a way to do it in the app but I'm concerned that stupid program will corrupt the already fragile table. Remember this program left Windows unbootable originally last year that necessitated the osxdaily fix I did last year that may have created the mess we have now.

I'll do it if you have confidence that TT won't make my iMac a boat anchor

Let me know your thoughts and I apologize for not having time machine backup and just crashplan.

No worries. Can you use TT to see if it allows the eDrive and the second OSX installation to be removed?

The only thing I see I can do is remove the edrive. I scrolled through all of the menus and don't see a way to remove a partition or that it shows any other OSX drive.
