Trouble getting a bootable image for Fatdog64-710

Invalid Signature

Failed to Load Image

I am running a laptop with Windows 10 on it. I made a CD with various tools - the built-in Windows, Infrarecorder, Cheetah, I believe ImgBurn. The CDs look reasonably normal:
help
boot.catalog
efiboot
fatdog
fix-usb.sh
grub.cfg
initrd
isolinux.bin
isolinux.cfg
vesamenu.c32
vmlinuz

I'm booting on a Windows 10 laptop that works. I have not tried to do things with loaders or partitions because I assume that I can just boot off of a CD.

I don't know but maybe it's a UEFI vs. regular boot, or a security issue?
I may need to turn off security in the bios.

Any ideas appreciated.
Thanks.

Now it tries to boot from the "9MB EFI FAT drive".

Is this the correct drive - shouldn't it say from the CD?

I get a Fatdog banner and some other stuff - like the usual menus and stuff but I never see the initrd and vmlinux ....... loading as with my other Fatdog64 702 version on another machine.

More troubleshooting.

My Windows 10 bootup still works.

I just had to wait long enough. I also decided to boot without a save file and I used a different cd. I like to try something irrelevantly different when something doesn't work.
