missing autoneogrub.mbr

I have a dual boot of windows 7 and Ubuntu 12.04.
I removed the Ubuntu entry from using easybcd and easy now I get the error of missing file autoneogrub.mbr in NST folder.
I was using windows bootloader to both both to windows and grub.
I don't have a cd drive so I can't use the windows repair disc.
Help me fix this.

Under Ubuntu, I see my Ubuntu filsystem / on dev/sda5 and /home on /dev/sda6, windows SYSTEM drive on dev/sda1 and the main windows installation on dev/sda2
