Hey, @mdooley, thanks for the responses.
My problem is when I am using the grub menu that is generated by eoan, not when I am trying to boot into eoan.
- I install eoan, no problem.
- In eoan, I customize the 40_custom file located in /etc/grub.d/ using the syntax you described.
in my case, it looks like this (as an example. I could use any other distro to boot, such as Arch or something else):
menuentry "My Newest Ubuntu Daily Build" {
set isofile="/home/<myusername>/Downloads/eoan-desktop-amd64.iso"
loopback loop (hd0,1)$isofile
linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/home/todd/Downloads/eoan-desktop-amd64.iso noprompt noeject quiet splash
initrd (loop)/casper/initrd
}
- I reboot and try to boot into this iso (or any other iso, for that matter).
- Screen is blank. No error, no grub prompt, unable to change to other TTY, nothing. Only option is to Ctrl+Alt+Delete to restart.
- My conclusion is that there is something with the way eoan boots different iso files from grub. Not the entries themselves, because they boot fine when I start with any other distro.
I hope what I am describing makes sense.
