I have no bootup screen.everything else works, its just black for a min and then shows the login screen. I need to be able to see it so i can change my BIOS bootup to cd to fix my xbox.
To get to your BIOS just hit F8 or "Delete" once every second until your BIOS screen comes up. If you have no boot picture you can still access your BIOS by hitting the keys during startup.
