I'm trying to make a iso, based on Ubuntu 18.04, that boots in both Bios
and UEFI mode. The application embedded in the Ubuntu base is not
installable, it is designed to run from a USB flash drive. I have no
idea how to use grub-mkrescue in this case. I've was trying to use
grub-mkimage and xorriso to accomplish this without success and it was
recommended that I try grub-mkrescue. The grub.cfg that I built follows:
#grub.cfg
set timeout=3
set color_highlight=black/light-magenta
menuentry 'Foxclone' {
set isofile="/efi/boot/foxclone025-02.iso"
loopback loop $isofile
linux (loop)/casper/vmlinuz.efi boot=casper
iso-scan/filename=$isofile noprompt noeject quiet splash
initrd (loop)/casper/initrd.lz
I really need some help getting started on this.
Thanks in advance
Larry
