Ubuntu 12.04 and Windows 7 - Dual Boot Failed - Status: 0xc000000f

[m.h.shams]

Hi All,

I have a Dell Latitude running ubuntu 12.04 and windows7. both OS are 64bit and everything was perfect until yesterday. when I received update manager notification in ubuntu.

there were some new packages to update (I didn't check exactly what). after update, I tried to restart my notebook but I was no longer able to start windows 7. Ubuntu is still ok and running without any issue.

here is my error in windows startup:

Windows Boot Manager
Windows failed to start. A recent hardware or software chance miht be the cause. To fix the problem:
1. Insert your windows installation disc and restart your computer.
2. Choose your language settings and click "Next."
3. Click "repair your computer."#

Status: 0xc000000f

I've tried windows 7 Repair disk, but it's says: "Not able to fix startup issue automatically"

here is fdisk info :

Any hope that i can get back my windows ?
