Bios and start up issues

1.When my PC starts it goes to the bootup screen with the choices of start normal and last known good configuration so on and so forth. If I start normal, it will go into windows(XP)and am able to work in a windows environment . If I reboot it does the same thing. I cannot boot normaly without seeing the blach menu bootup screen.
2.When I go into bios, load old values window is showing and I can't get rid of it to I can make some changes. Even if I say y/n the screen stays there and will not go away. Escape does not work.
I would appreciate any advice given.
