So no other recommendations? Are the MFT corruptions caused by further installs and upgrades?

seem to indicate a partitioning activity. Do you recall any manual activity for changing/resizing your partitions? If you have critical data, My suggestion is to try data recovery software to retrieve your data, and re-install windows and put your data back.

Yes I used this program to expand my windows partition: http://www.partitionwizard.com/ as per https://www.youtube.com/watch?v=WeKeawqxUa0.

"Yes I will try to remember every detail:

So my windows side was running out of space so I decided to expand it using this tool: http://www.partitionwizard.com/ following this instructional video: https://www.youtube.com/watch?v=WeKeawqxUa0. After that I used windows quite a while and it correctly showed my windows drive to the increased size. I don't think I ever went back into the mac side until one day I ran some anti-spyware programs spywarebot and malwarebytes on the windows side because my credit card numbers kept being used and I wondered if there was a keylogger on windows. After I did that I went back to the mac side to run updates and thats when I noticed my bootcamp was gone and I could not log back in. So I figured it was the partition extending I did way back. Tried everything to fix it running verify and repair but nothing. I then tried to login holding the alt option key at boot but only the mac drive showed. Even tried to get my IT guys at work to help but they were clueless. One upgraded my Mac from Lion to Mountain Lion to see if it would help. I then upgraded to Yosemite. And tried verifying and repairing again. I then restarted and pressed option key and my windows drive was showing but when I clicked on it I get the black screen saying: Missing OS."

Should have the re-read the OP. 😉

One option is to re-install Windows on the same partition (which will backup your current Windows installation) and it at least let you gain access to your files.

Please see http://windows.microsoft.com/en-us/windows/installing-reinstalling-windows#1TC=w indows-7.

But it says?...

Custom. This option replaces your current version of Windows with Windows 7, but doesn't preserve your files, settings, and programs. It's sometimes referred to as a clean installation for that reason.

I believe you can only upgrade when you are inside of windows...

Is it possible for you to move the disk to a PC?

That is a bit too much work. There is a utility called PhotoRec (there are commercial equivalents as well), which you can try, to extract your Windows files. PhotoRec is on the same page as Testdisk. Do you want to take a look?
