After installing Mavericks Windows won't start

Hello folks,
So yesterday I upgraded from ML to Mavericks and I think it messed up my windows 7 partition :|
after I boot from the windows partition right when the windows logo appears the startup fails and reboots then goes to windows repair, I tried to do a startup repair it didn't work. And i'm not the only one with that issue, A lot are complaining. So help me folks!

 

Sorry for my late reply ,,
I had 2 partitions when I upgraded to Mavericks.
And the issue appears to be that Mavericks corrupted the windows local disk, So every time I start windows I get an error in a blue screen saying UNMOUNTABLE_BOOT_VOLUME
and I tried to use some commands in the cmd like chkdsk, fixboot, fixmbr
none worked

And here is the output for sudo fdisk /dev/rdisk0

Code:

I see what you are saying, Though I'm 100% sure that just before I install mavericks windows was running properly and after the install finished I booted to windows and the issue occurred.

And the weird part is that I can view my windows partition right from my mac.
But windows is not able to mount it thinking it's corrupted :|

 

I tried to run CHKDSK but windows couldn't do it saying that the disk is in RAW format and CHKDSK is not available for RAW formats, But actually my format is NTFS but windows thinks it's RAW because it's corrupted.

 

Great!, Thanks a lot for your help. I'll try ASAP

 

Yup, It was a demanding route and I haven't succeeded :|

However, I'm only left with reinstalling windows and I did not want to do that because I have games in my program files folder that I can't use if I just copy them and put them back after Installing windows again.

I really appreciated your help though, Thanks a lot.
