No Hard drives has been found

[Emanuel Mauritzson <mauen bostream nu>]

I have a problem when i trying to install Red Hat.

This message occur when i trying to install

"No hard drives have been  found you probably need to manually choose 
drivers for the installation to succed"
---------------------
And after that
------------------------
No device drivers has been loaded for your system would you like to load 
any now
-------------------------------------------------------------------------------------
then i can choose a lot of devices but to me it only looks like 
networkcards devices
so when i push done and enter the X graph mode. I can fill out Language, 
Keybord and mouse settings then the program reboot the computer and 
gives the message no hard disc is found.


Could somebody help me..Know my english not so good..
