The innards of the iso image were different from f36. I can boot
the .iso file itself directly from a grub2 entry with a little
work. I've got a directory named "images" in a partition with the
UUID of 7ad8f114-5b24-47bb-86c6-0b229519d76c and I use this grub2
gibberish:
set data_usb_uuid="7ad8f114-5b24-47bb-86c6-0b229519d76c"
function set_data_usb_root {
insmod ext2
insmod gzio
insmod part_gpt
insmod part_msdos
load_env bootvid
set root='hd0,msdos2'
search --no-floppy --fs-uuid --set=root ${data_usb_uuid}
}
menuentry 'Fedora Workstation Live 64-bit 37 (1.7)' {
set_data_usb_root
set isofile="/images/Fedora-Workstation-Live-x86_64-37-1.7.iso"
loopback loop "$isofile"
linux (loop)/images/pxeboot/vmlinuz root=live:CDLABEL=Fedora-WS-Live-37-1-7 iso-scan/filename="$isofile" rd.live.image
initrd (loop)/images/pxeboot/initrd.img
}
This is all actually on a USB stick where I have grub installed,
but with appropriate modification to uuid and partition numbers
(from the hd0,msdos2 thing) it should work from a hard disk as well.
I've got a slew of different iso files on the USB stick and menu
entries for all of them, so it is handy to do installs as well
as rescue operations. Takes a while to get it set up and working,
but is quite useful once it works. I used this info to build it:
