Sometimes it can be a struggle to get into the asus laptop bios key. A login screen appears on most machines as soon as you power up; check for text showing which button to click for Startup control. It's usually F1, F2, F12, or Remove. You may only have to click the correct button for a few seconds before the initialization monitor disappears— and sometimes you don't even get it. If there is no initialization display at all— or if it pulses too soon for you to decipher it— try to rapidly click some of the above keys to "mark" the correct one. This should carry you to the asus bios key. If everything else fails, please consult the guide.
