Sorry for asking this question again, asked it here a long time ago but didn't get any answers.
Since I setted up dual boot with Ubuntu and Windows 8 I have this "problem", grub menu shows up, if I press any key, everything freezes for about 2-5 seconds, after that everything works fine.
It's kind of annoying if I just want to select to boot windows and have to wait for "so long"
I couldn't find any answers, maybe someone knows how to fix this
