First off, making a bootable CD is separate from making the HD
image.  But Linux is an advanced OS that has everything you need to
do this.

To make a image of any partition or media, exactly as it, use
"dd".  Of course you'll need to have a larger partition to store

The best move is to just put the HD from the other system in that
same system and run the "dd".  You can even use "dd" to install the
boot sector and you're set!  Complete clone!

If you want to get fancy, put a $20 removable HD tray in the
system and you've got a system for cloning!

[ BTW, nice of you to post non-text messages with a commercial
product like Outlook.  Not a flame, just a notice of the irony. ]

I personally like Drive Image Professional from PowerQuest.  At
$220 for the 10-PC license, it's probably worth it than trying to
build such a flexible system out of Linux.  But do it for the
challenge if you like, you can make nice text dialog boxes with
various RedHat installer components.

Why not?  Did your boot disk contain the proper devices in /dev? 
Did you "dd" the boot sector?
