Hi, my laptop won't start up it's a toshiba windows 7. When i turn it on it comes up with a messag etelling me to insert a boot disk or press any key. I don't have a boot disk so i press any key and it keeps repeating the same message over and over again everytime i press any key. When I press control alt delete, it takes me to a page that says toshiba, then at the bottom it would tell me to press f2 for setup utility and f12 for boot manager. I've tried everything i could think of to solve this problem but it still won't work. I researched it on the toshiba webstr but it's tells you to go to bios. I don't know where to access bios. It only happend today, I haven't experienced this before. Please help me I need my laptop workig as soon as possible. I need it before school starts because my homework is all online. Any help would be appreciated. Thank you!
