Windows 7 not bootable after upgrade

Hello All,

I have just upgraded to Maverick OS X 10.9 (13A603). Now as many of the others I am unable to boot into my Windows 7.
The partition is NOT LOST. I can still see the partions and the files in the Windows HD just cannot boot with it.

I guess it can be easily fixed using gdisk for experts.

Anyhelp in this matter is greatly appreciated.

My outputs are:

$ diskutil list
