Remove any CD disks, flash drives, memory cards, PC cards, USB external drives and then try booting again. If none of the above are installed then there is no operating system on your hard drive. The hard drive MAY have a restore partition that can be used to restore the notebook to factory state. Click on the link below to learn how.
