Boot up Go in Bios, press button intermitently try F2 or F12, once in there go to bootable device options menu, make shure "Boot from HD" is first in the the list, save settings then exit, if you get the same message, repeat the above procedure, this time select "boot from CD drive" as first option save settings and exit, before rebooting put the installation disk in the drive, reinstall operating system,
If you don't have a installation disk, and quite a few don't,
it probably means that there is a hidden partion on your HD drive with a copy of your operation system you would need to access it with a bootable device, to reload it back in, go to there web site fore more details.
