boot of iso-image

Hello,

i am trying to install CAElinux2010 on a Athlon AMD 64bits.
i would like to boot the live DVD iso image.

First i installed kubuntu 9.10
And i upgrade the grub with this entry :

[code:1]menuentry "ISO Install - caelinux pas loop" {
insmod loopback
insmod iso9660
set isofile="/caelinux2010.iso"
loopback loop (hd0,1)$isofile
linux /casper_cae/vmlinuz locale=fr_FR bootkbd=fr console-setup/layoutcode=fr iso-scan/filename=$isofile boot=casper file=/cdrom/preseed/ubuntu.seed noprompt quiet splash --
initrd /casper_cae/initrd.gz
}
[/code:1]

The boot sequence is ok and i have the purple screen during about 1 min.
Then i have an error message :
" (initramfs) unable to find a medium containing a live file system"

I try to use an USB key with the iso file and remplace (hd0,1) by (hd1,1) in the grub file, but no sucess....

Could you help me ?
thanks
Emmanuel

Caelinux is setup so you do not have to install the dvd. Simply select the dvd drive as the first boot option in your bios. or select it through the quick boot option menu by pressing F9 or F12 (depends on motherboard)

Thanks for the response !

But I cannot boot with the DVD!
I have messages :
&quot;
Loading /casper/vmlinuz.................
Loading /casper/initrd.gz............................ready
&quot;

And then, the PC crashs !

So I would like to install without DVD by booting with an isofile on the disk

Any idea ?<br /><br />Post edited by: laurent, at: 2010/09/28 11:06
