Help with Windows XP and Windows 7 boot issue

Hello,
First, the computere had windows XP installed on the PC with some issues. We installed Windows 7 on the same drive.
Now, when the computer boots a menu is presented and we have to choose windows XP or Windows 7. The default is set to Windows XP unfortunately.
I want to remove the reference to windows XP and make the computer start Windows 7 automatically.

1.) Currently, when I try to edit to boot menu in EasyBCD, it only shows a default of Windows 7. Possibly because, I selected the Win7 version to boot.
2.) If I select Windows XP options, I endup getting a blue scree partly the windows xp has many issues in the install..

Questions:
A.) How do I make Windows 7 the only boot selection in my situation
B.) I have removed the Windows.old (xp) install, but the references to XP on the PC confuses me.
Thanks
