An year and a half ago, I installed Ubuntu on my computer using Wubi. After a while I decided to install Ubuntu on a separate partition. So I uninstalled the Ubuntu using Wubi, and installed Ubuntu on a separate partition by booting from the Ubuntu ISO.
Though Wubi uninstalled Ubuntu from my Windows partition it did not remove the option in the boot menu. So now when I boot, the grub menu has option for Windows and Ubuntu, but if I choose Windows from the menu, I again get two options - Windows and Ubuntu, this time from the Windows boot loader. If I choose Ubuntu, it just shows and error asks to go back.
So how do I remove the option?
EDIT: I have tried to use bcdedit but it did not help. If I run bcdedit on the command prompt, this is the output:
Windows Boot Manager

According to this I should only have one entry which should be named Windows 7 Ultimate (recovered)
but instead when I boot I have two entries, one named Windows 7 and the other named Ubuntu. I couldn't find any answer by googling.
I also tried to set the timeout to 0, but again for no help, the boot screen still waits three seconds before selecting the default option.
