When I first switched on my Satellite Pro Toshiba laptop after returning from a weeks holiday ,after signing in the screen went black with the message "Boot failure : a proper digital signature was not found "I have followed all instructions and entered the Bios set up facility but when I get to Boot mode that is highlighted in grey rather than blue as all the other components are. Does anyone have any ideas as I am fast running out of options. Any help greatly appreciated!
