RH 7.3 on PowerEdge 1800 installation problem

[slide_jimmy2001]

I've tried to install RedHat 7.3 on Dell PowerEdge 1800 and i've got this problem:

The CD booted up, gone into installation as usual.

After selecting "Language" & "Keyboard", there's this Question "What type of media contains the package to be installed". The only option I have is  "Hard Drive". After choosing "Hard Drive" it says that it couldnt find the install image. And Im stuck

I tried installing RedHat9.0 and it works fine. But I really need RedHat7.3 instead of 9.0. Please help.

I think RH7.3 installer is not able to communicate with your CD / DVD properly, may be new hardware etc. if its giving HD install option only then save image on HDD and do install from itself.
Or
Try changing your cd drive.
