Turned off computer during update

Hello, I have a really nasty problem that I haven't been able to solve after looking for a solution for weeks.

I have a MacBook Pro with Bootcamp installed, right now I'm writing from Windows 7. A few weeks ago, I turned on my laptop as usual, and an update started. I wandered off while it was updating, and long story short, friend shut down the laptop by holding the power button.

Now I can't use OSX. When hit alt after turning on computer, I no longer get to choose between OSX and Windows 7, all I get is Windows 7.

When I try to access my HFS/OSX partition (E:) from Windows 7 explored, I notice that many folders that should be there are missing, and most of the times I get a blue screen memory leak error when going inside certain folders.

Re-installing everything isn't an option, I really need to re-establish my OSX, because I have a ton of valuable files in there, like music, which is sorted among thousands of folders with special file naming, and I totally don't want to use a disk recovery program to recover my information with no folder structure or order...

Has anyone been trough this?

Well, not my lucky day, seems the disc is way damaged.

I tried running the installer from disc, and I got an error. Restarted automatically.

On the second try, I get a message saying that the disc needs to be Journaled, on Disc Utilities > File > Journal Disc or something like that.

When I try to do this, the Journal option appears greyed out, can't do it.

On Disc Utilities I try to diagnose and repair the disc, and I get a log saying it has an invalid node structure or something similar, and asks me to backup and format the disc.

So, is there any other way to repair my disc? Or in any case, is there a way to temporarily access my OSX folders and save them to an external HD?

You lost your data. That's the reason you should make backups

I know for a fact that my data is still there, the disc is still phisically full according to Windows, and I was able to retrieve all of my mp3 files using a hard drive recovery program.

Alas, these programs break the folder structure and file name completely, leaving over 52,000 mp3 unsorted, randomly named, and on a same folder... which *****.

There should be a way to repair the damage done.

Invalid Node structure is about as bad as it gets. You're gonna need something like this to try & fix that:

There is no guarantee that DiskWarrior will work, That's why you backup.

Is there a way without the disk? I did the First Aid but it didn't work. And one of the HD is greyed out (Macintosh HD).
