What should I do if I cannot boot my VAIO computer from the floppy disk drive?

• Turn on your VAIO computer and press the F11 key repeatedly until the VAIO logo disappears.
  If the computer does not boot, restart the computer and try again.

• Check if a USB storage device is available.
  The USB ports are disabled if Disabled is selected for the USB ports in the BIOS setup screen. In such a case, change the BIOS setting. [Details]
