Toshiba L850D cannot boot.

[Phurba Sherpa]

I tried to boot my Toshiba L850D but all it shows it checking media and fail. I read the solution in this http/www.tomshardware.com/forum/85143-35-toshiba-satellite-boot also but sadly there it says to go to the bios and change the boot mode but sadly in my laptop that option is there but it is disabled i cannot change it. Now can i boot my laptop??

There is probably a password for the bios. Would you happen to know it? if not call the manufacturer and ask for it.
