Sometimes when you install multiple copies of operating systems and then uninstall, you might face the problem that the bootloader entry doesn't get removed automatically. It starts getting weird when you have number of same operating system bootload entries. I had myself installed Ubuntu 12.04 inside Windows 7 and then, for some reason, had to switch to version 14.04.1. What I got was two Ubuntu's appearing at my boot screen.
The solution to this problem (in Windows 7) is:
1. Open cmd in Windows 7 as administrator
2. Write this command
3. Your area of interest in this output will be this line
4. Read carefully what entry you want to delete from here and copy the identifier of that entry into your clipboard. I couldn't do it from console also I don't run such long strings to avoid typing mistakes plus it requires you to look hard. What I did was
which is nothing but redirecting output to some file.
Now you can easily copy into clipboard by opening that file in notepad.
5. Paste this into command as follows
and then press "return" key.
Be careful manipulating with bsdedit as you're working as an administrator.
Good luck.
