AMD HP Pavilon incompatible EFI Boot manager/ Can't boot on Cosmic Cuttlefish USB

I used Unetbootin to make a USB bootable disk with Cosmic Cuttlefish pre-release and post. It is the same USB stick I've used for at least 4 previous Linux systems, Ubuntu and Fedora. (On this same laptop.) Immediately on boot it says it can't find MMX64.efi. Looking in the boot directories there is no such efi file. Doing research I find I have to modify the EFI or turn off EFI in the BIOS. I have an HP Pavilion laptop with AMD A8 Elite Quad-core. Turning off the bios Legacy just makes the boot fail even before I get the Can't find error message. Trying to use efibootmgr it says: "EFI variables are not supported on this system." Doing more research efibootmgr is for Intel.
Any suggestions would be helpful. Trying to upgrade to my namesake, FeiWuzei 飞乌贼 is flying cuttlefish in Chinese.

What tool did you use to make installer? Have seen similar issue with Rufus installer tool. Some work arounds: askubuntu.com/questions/1085550/… My latest update of grub has in /EFI/Boot/ a file mmx64.efi. That is a key manager related to UEFI Secure boot keys which we normally do not directly mess with.

"I used Unetbootin to make a USB bootable disk with Cosmic Cuttlefish" I was thinking about trying a different one, but I've used Unetbootin before as well as YUMI, windows app, under Wine.

If you do not need BIOS boot. UEFI only USB key, just extract ISO ( 7 zip or similar) to FAT32 formatted flash drive partition & set boot flag. askubuntu.com/questions/395879/…

Yep, Just rename the boot file. Make it happy. "Never does what I want only what I tell it."
