#1 GRUB on screen and nothing else

[wal_2004]

Hi
after installation and reboot, i just see GRUB on
screen and keyboard is locked.
i have try FDISK /MBR and after reboot he tells me that
there is no system !
i have already try to install ipcop,A@H and debian on
this computer with success, so it should not be a
hardware problem

thanks for help
