Install Redhat Linux

Hi. Totally new to Linux here. Never once installed on my own. Problem is I cannot get my PC to boot off of Cd. I tried two different CD’s. Then created a boot disk. Started the install. Gets to the part where it needs to access the CD and it tells me it cannot find the Redhat CD. I have tried the two different CD’s, three different PC’s. I am at a loss here. Help.
