I have a Toshiba Satellite L875D-s7332 laptop that won't boot from either the ODD or USB. It is running windows 8.x and has a desktop utility that allows you to change system settings including Boot order (which I have). It continually just boots the hard drive despite the settings. I never found a way to get into the bios on machine boot up no matter what combination of power on + other keys I tried. I checked and tried many different suggestions from other sites but still nothing. Any ideas or did Toshiba do something?
