Problem is Fedora Media Writer is to create a USB with 
Fedora Media on it. I'm NOT having an issue with 
installing Fedora. I have built an open source project 
using my Fedora machines since 2004, and have created 
CD, and usb media, and even loaded the resulting kernel 
and ramdisk.lzma from grub2 with no issue. It is now 
getting a process that will do the same for a UEFI only 
boot system on Dell and seems newer Lenova machine.
Have now had two things that show using grub2-install to 
setup up, but that fails on my Fedora 33 with:

grub2-install: error: this utility cannot be used for EFI 
platforms because it does not support UEFI Secure Boot.

I don't want to create a UEFI Secure boot, since I have no 
way to pay for the expensive process of getting an official 
signature for the kernels I build from kernel.org source 
code. Kernels are about 10M in size, and the 
ramdisk.lzma is about 30M with supporting file system 
that then runs in Ram. In contrast the Fedora live Image 
is about 2G in size, and doesn't include a number of 
packages that are needed for the disk imaging. 

>From my email from Clonzillia they use Unbunta or 
Debian live-cd to support UEFI boot, and then add there 
stuff on top of it. I've used Fedora since 2004, and its 
worked well. So going from a 40M solution that works to 
a solution that would require 2000M plus require internet 
access to download the additional packages needed 
seems Dumb. 

Perhaps I'm missing something on why there is so 
difficult an option to create a UEFI non-secure boot USB. 
Like I mentioned the person can physically take the drive 
out of the Dell 3080 machine, and connect it to a 3070 
machine, and do the image process with no issue, and 
then put the drive back in the 3080 machine?? 

All it takes to add it to the regular grub2 boot on Fedora 
machines is the following lines in 40_custom file, and 
copying the bz5x13.15 kernel file and the ramdisk.lzma 
file into /boot. 

menuentry G4L {
	linux /bz5x13.15 root=/dev/ram0
	initrd /ramdisk.lzma
}
