Red Hat :: Booting Centos 5.4 - CentOS CD Not Found In Any Of The Media Drives

Since RHEL is similar to CentOS posting it here.

Upon booting from DVD, i get the below error: "CentOS CD Not found in any of the media drives. Please insert CentOS CD and press OK."

I have IDE Sony DVD RW AW-G170.

BIOS Setting:

Downloaded the CentOS-5.4-i386-bin-DVD image from centos.org from DVD.torrent using bittorrent file.
When booting from the DVD, it gives me the boot prompt:

Upon pressing enter, the log messages of the boot detect the media drive as: hdc: Sony DVD RW AW-G170 IDE ATAPI CD.

The below steps occur:
1) Select the keyboard type: selected us

2) Select the Language : selected us

3) Select the image:
- Local CDROM
- Hard Drive
- NFS Image
...
...
selected Local CDROM

Then the above error "CentOS CD Not found in any of the media drives. Please insert CentOS CD and press OK."

The booting steps does not ask the for media check step.

The below methods have been tried to solve the problem:

- Burnt the image in another 2 DVDs but the same error "CentOS CD Not found in any of the media drives. Please insert CentOS CD and press OK."

- Upon burning the DVD image , selected the DVD read speed: 8x. Upon burning the DVD selected 18x for burning. and then tried to boot with that DVD

- At the boot prompt entered : linux hdc=cdrom replaced hdc=hdb but the error remains.
