Hello

The screenshot is too small for me to see anything in it, but it sounds like you didn't burn the iso file to disk as an image, but perhaps you simply copied it to the disk. Check the following thread for instructions on properly burning iso files as an image and then booting with your new disk:

No, no...of that I am sure...I burned it as an ISO to a disk

Maybe try testing your newly burned disk in a different computer. If it fails there, too, I'd still be thinking the disk may have been improperly burned. Otherwise, it should boot if the disk was burned properly, there are no hardware incompatibility issues, and you are properly rebooting after setting your BIOS to boot the system from a CD/DVD.

Hopefully someone else with chime in here if they have any ideas on it.
