Help with Fedora

[Cityscape]

I have a Feadora 12 Live CD. It booted up fine on my 700 Mhz computer. I've since then put a new HDD in with which I intended to install Fedora on. But now i get this message

No root device found. Boot has failed, sleeping forever

What does this mean? How do get the Live CD to boot?

I'd suggest first just going back and double checking the disk and it's installation.  Just make sure that you got everything right.

Can you test the HDD as well to insure that it's okay?

I burnt the CD today and it worked fine with the other HDD. I don't see how the CD could suddenly go bad in 10 minutes. The hard worked fine yesterday. I did however remove my secondary drive because it seems broken but the Live CD still gives the error.

Sorry, I was referring to the installation of the HDD, double check your jumper settings and cable connections.

Make sure it is booting from the CD.
Check the BIOS.  You may have to change the boot order.
Do as Quantos said and check the jumper. If there is no other disk, then use master and not cable select.

You may also want to use another Live CD such as knoppix 5.x or a bsd such as  jibbed or bsdanywhere.
Some distributions will occasionally have trouble detecting drives.

Well I found out that it is a CD/DVD drive problem. I put a Vista disc in and after it booted to the install it told me that it could not find a CD/DVD driver. I tried XP and it gave me a stop error.

It looks like a freak CD drive problem where it can boot the CD but not recognize the drive after booting.  I'll try to fix. I'll post back if I have probs.
