as you previously suggested. of course, if the timeout in grub.conf is zero,
and hiddenmenu is set, then additional  problems may occur. even more
complicated is a case where the keyboard is connected by usb, since grub is
famous for mostly ignoring the usb keyboards. but let's see what happens
after removing rhgb and quiet.
btw, grub.conf can be modified offline using install media's rescue mode or
any recent linux live cd.
