Windows failed to start

I am on the verge of exploding due to the poor and terrible execution of this program.

I have been using BootCamp Windows 7 x64 Ultimate with this MacBook Pro (2.66GHz i7 intel core & 8GB ram) for almost 4 years.
All was fine throughout those years even with several OSX grades and I'm now on Mountain Lion 10.8.4
About a year ago I downloaded Parallels & made a VM with my existing BootCamp, which also worked fine for a year.
Just today I decided to open it up again after almost 8 months. The thing went through some process and now my BootCamp is broken.

Windows will not load under any condition and it gives the message "Windows failed to start. A recent hardware or software change might be the problem"
BootCamp, parallels VM, all safe modes, and startup repair all do not work. Even system restore fails.

I have searched the internet for almost 3 hours and nothing works. I really don't want to reinstall, as I have lots of programs and have not backed it up.
I bought both Windows and Parallels, amounting to almost $400 so I really need a solution

Thank you
