I have a Toshiba Satellite p855. I caught the GANDCRAB V5.4 so I reset my windows 10 and now it acts as if I have no hard drive. I can't boot up into BIOS, if I hit any key including F2 or F12 it keeps scrolling " reboot and select proper boot device or incert boot media in selected boot device and hit any key" no matter what I do we get this error What are my choices
