If you are trying to restart your computer from a floppy diskette, CD, or any other disc follow below suggestions. Confirm that no floppy diskette or CD is inside the computer because the computer perhaps tries to boot from a non- bootable disk, which might cause this error.

  1. Remove the CD or floppy diskette from the computer and keep it back inside and press any key to continue.
  2. Try restarting the computer.
  3. Rebuild the bootable diskette or CD you are attempting to boot because the disc may be bad. If this is a DVD (not burned) or CD try cleaning the disc or make sure there are no smudges or finger prints on the bottom of the disc.
  4. Try booting the diskette or disc in another computer. If that computer can restart without the error it is probably you have an issue with your drive.
