You need to edit the boot ini
If the first one is working then delete the second entry
Click Start>right click on My Computer>Properties>Advanced>Startup and recovery settings>Edit
and then just delete the entry that is no good
Turn off Welcome Screen
Start > Control Panel > User Accounts
Select "Change the way users log on or off"
Uncheck the "Welcome Screen" option
Click "Apply Options"
The settings will take effect when you log off.
The "Log On" option also changes the way "Ctrl Alt Del" works...
Under the "Welcome Screen" option you are taken into the "Task Manager" dialog box.
Under the "Log On Screen" you are given the Windows Security dialog box, which gives you far more options!
The "Log On Screen" also renames "Turn Off Computer" on the Start menu to "Shut Down".
The other main feature you get is the ability to log on to ANY user account, whereas under the "Welcome Screen" you can NOT access hidden users.
So, as you can see there are benefits to using the "Log On Screen" over the "Welcome Screen" option.
