Hi,
Kindly do excuse me if this forum is not the right place to post this question: 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:

Hard Disk Configuration:
SATA Port 0 : Type [auto]
PATA Secondary Master : SONY DVD RW AW-G170

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.

Kindly do suggest whether i am doing anything wrong.

CentOS is binary compatible and is built from RHEL source. So this IS where you should post. I only use CentOS, and this is only forum on LQ I monitor.

That being said, it looks like kernel is not finding drivers for your DVD. Either that, or there is something wrong with the ISO. I suggest to download ISO again, and/or to use md5 sum to check downloaded ISO file. If file is OK, I suggest trying with another DVD device or try changing IDE settings in BIOS (AHCI/RAID section).
