hdd booting from iso with grub2 for KDE_Plasma_5.x86_64-0.0.4.iso

[francois.e]

I am trying to run KDE_Plasma_5.x86_64-0.0.4.iso from hdd. I have tried in 40_custom:
menuentry "KDE_Plasma_5.x86_64-0.0.4.iso" {
insmod loopback
insmod iso9660
set isofile="/home/fl/Downloads/isos/"
#recherche de la partition dans laquelle se trouve le fichier ISO et montage de celle ci dans "/"
search -sf $isofile
#Montage du fichier ISO dans (loop)/
loopback loop $isofile
echo 'Chargement du noyau Linux ...'
linux (loop)/mnt/disk/boot/x86_64/loader/linux iso-scan/filename=$isofile boot=boot file=/cdrom/preseed/ubuntu.seed quiet splash --
echo 'Chargement du disque mémoire initial ...'
initrd (loop)/mnt/disk/boot/x86_64/loader/initrd
}

I do not know what to put as argument for file= instead of /cdrom/preseed/ubuntu.seed. And maybe I have got it all wrong.

Any suggestion would be really appreciated. Thanks.

Not an answer to your question, and I have not yet had time to try this, but I made this note the other day:

## boot an iso from primary hard drive
sudo aptitude install grml-rescueboot
put iso(s) in /boot/grml
sudo update-grub

I think grml came up on another thread here.

the "grml-rescueboot" dose work with the vivid-desktop-amd64.iso ,,,,,,,,,I have used it with that.

what is this "KDE_Plasma_5.x86_64-0.0.4.iso" ?

@vinny:
This was the killer question.

I though I was working with the kubuntu plasma 5 edition, but KDE_Plasma_5.x86_64-0.0.4.iso is opensuse. I was working with the wrong iso. I will try with utopic-desktop-amd64.iso and report if there is any problem.

Thanks.

Ok. There it is. It works:
menuentry ".. plasma5 utopic-desktop-amd64.iso" {
insmod loopback
insmod iso9660
set isofile="/home/fl/Downloads/isos/utopic-desktop-amd64.iso"
#recherche de la partition dans laquelle se trouve le fichier ISO et montage de celle ci dans "/"
search -sf $isofile
#Montage du fichier ISO dans (loop)/
loopback loop $isofile
echo 'Chargement du noyau Linux ...'
linux (loop)/casper/vmlinuz iso-scan/filename=$isofile boot=casper file=/cdrom/preseed/kubuntu-plasma5.seed quiet persistent splash --
echo 'Chargement du disque mémoire initial ...'
initrd (loop)/casper/initrd.lz

Is there as simple way to add persistence?
