This question already has an answer here:

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

device                  partition=V:
path                    \bootmgr

Windows Boot Loader

device                  partition=C:
path                    \WINDOWS\system32\winload.exe
description             Windows 7 Ultimate (recovered) 
locale                  en-US
recoverysequence        {e58e9c4d-dc5b-11e1-be69-bb3b6bb64ef4}
recoveryenabled         Yes
osdevice                partition=C:
systemroot              \WINDOWS

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.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Start menu > type 'msconfig' > within the 'boot' tab, remove the entry from there.
