I was told to recover my computer to the factory setting because of a virus I received. I had done this my other computer without a disk. NOW, I can't get in it. I see the TOSHIBA LEADING INNOVATION picture then a black screen that tells me that it is not bootable. My computer does not have a Serial / Model number to be found. I cannot locate a recovery disk. PLEASE, TELL ME YOU CAN HELP ME TO GET MY COMPUTER WORKING.
