Hi, I have done this and will try to help you.
Re point 1. It's irrelevant wrt booting isos on a Grub USB stick
Re point 2. Here is how I do it...
The following grub configuration examples assume the ISOs are placed in
an /iso subdirectory. Set up a reference to the device containing the
ISO images using either UUID:
set imgdevpath='/dev/disk/by-uuid/deadbeef-cafe-babe-feed-cafe15bada55'
or disk label:
set imgdevpath='/dev/disk/by-label/boot'
Then build menu items to boot the ISO images. Here are some examples:
menuentry 'archlinux i686' {
set isofile='/iso/archlinux-2014.09.03-dual.iso'
loopback loop $isofile
linux (loop)/arch/boot/i686/vmlinuz archisolabel=ARCH_201409
img_dev=$imgdevpath img_loop=$isofile earlymodules=loop nomodeset
initrd (loop)/arch/boot/i686/archiso.img
}
menuentry 'System Rescue CD' {
set isofile="/iso/systemrescuecd-x86-4.4.1.iso"
loopback loop $isofile
linux (loop)/isolinux/rescue32 isoloop=$isofile nomodeset
initrd (loop)/isolinux/initram.igz
}
menuentry 'Tails' {
set isofile="/iso/tails-i386-1.2.1.iso"
loopback loop $isofile
linux (loop)/live/vmlinuz fromiso=$imgdevpath/$isofile boot=live
config noswap nopersistent nomodeset
initrd (loop)/live/initrd.img
}
You'll need to craft your own for Ubuntu because I don't use it and I
don't know what it would need. But these examples should set you on your
way.
Hope it helps.
John
