I can now report that I used a Verbatim DVD+R disk and successfully burned a rescue disk, which after shutting down, then using the F12 key to get to the boot menu and changing it to the DVD drive, then hitting the enter key, the disk then booted up OK with no problems. It does take a couple of minutes to boot to the main page as any disk is slower than the main hard drive, however there were no problems for me.
I will now suggest trying again with a different make of disk, and also doing some checks of your DVD/CD drive with other known to be good disks to make sure the drive is working correctly.
