Unable to Boot After Burning DVD iso Disk

[Jeffrey D. Yuille]

Hello,

    I just burned a Fedora Core 6 DVD ISO image by using K3b.  The burn 
went fine, buy now I am having a problem getting the disk to boot.  I 
already changed the bios setting of my laptop (I am using an IBM 
ThinkPad T-30) to allow the DVD drive to be the first drive to be 
booted.  I was also able to previously burn this same Fedora Core 6 DVD 
ISO image using GnomeBaker as well as the Nautilus burner but with the 
same results of producing a disk that it unable to be booted from. Has 
anyone else had this problem?  Is there something wrong with the DVD iso 
image? I also checked out the checksum of the disk and everythings seems 
to be okay with this as well. Anything help would be greatly appreciated.
