How do I remove an historical dual boot startup?

[mcra]

I have recently "tried" a Linux .ISO CD and took the wrong option and partially installed ubuntu as a dual boot option. Since that time I have discovered Oracle VirtualBox and much prefer this route to look at and experiment with linux. However I have a legacy of my untutored fiddling in the form of a splash screen at power up [straight after POST] of a dual boot option - Windows 7 or ubuntu p which I dont want. Its an annoyance rather than a catastrophy but I am at a loss as what/how to 'edit' this startup file to remove the dual bootup option. I have tried FIXMBR from the repair option but the dual selection option remains. Surely this is a straightforward edit of the appropriate file but which file and with which edit utility?

Thanks theog - as my post refers, I had 'found' a reference to EasyBCD and have used it to effect. Thanks for your response
