I assume that you have burned the iso to a disk? If so, I recommend using Rufus to make the bootable iso. I use Balancia Etcher to make bootable usb drives. I have found that other image burning software does not properly burn the ISO’s. Rufus also has a nice drop down box to choose bios or efi bootable images. I think you have made an efi bootable image for a computer that only supports bios. Just my guess.
