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
 
Update. I pressed 0 and the pc brings me to a screen I can do several things. When I try to go into safe mode or troubleshooting to get to command prompt it starts to run like it normally does to go into safe mode then freezes. I let it run for 10 hrs ... Nothing Just freezes

If I select start Windows the Windows logo pops up and freezes

I have my windows 7 disk in my pc but it does not go there
Any suggestions?
