You need to boot into NT (VGA MODE) there is an option at the menu selection screen

if this failes because your timer is set to zero heres what to do..... start up, press crtl+alt+del login as usual..(ofcourse you wont be able to see what you are doing but bare with me) when you are sure you are logged in(the pcu wont be making any nmore sounds then) press crtl+esc tap the up arrow three times and press enter... now type cmd and press enter ... press alt+enter and if all things are ok you will see a dos box... go to the c:\ and type " attrib -h -a -r " now type boot.ini and set the timer to 10 sec.. put the attribs back and you are there... or approach you c:\ from another pc... good luck

Another try: hold down "key-up" during boot (characters on the upper left)
