1. Open up the command prompt and type “
bcdedit”. As an
Administrator.
2.Basically you will now get a lists of all the OS's that are registered to the Windows bootmanage For instance, as you can see, there is an entry called “Windows Legacy OS Loader”, the identifier of which contains the value “{ntldr}”. From this, I can tell the WindowsLegacy OS Loader used to load Windows XP on this system, since the value of ntldr is default for winxp boot-loader.
3.Now type bcdedit /delete {ntldr} /f
remember to type it as you see it here with all the spaces. Also if you right click the command prompt ans select mark it will allow you to copy the correct identifier for later use.
4.After you see the message “The operation completed successfully”, restart your computer. And you will no longer see this boot option screen anymore.
All the best and happy modding
