Topic: [SOLVED] Boot directly from iso file on usb stick

Hi,

I want to create a usb-drive with multiple iso files on them and be able to boot from these directly using grub2.

So I have copied the gparted-iso to the usb and created a grub2 entry like this:

menuentry "Gparted 0.3.9.4" {
        loopback loop /boot/iso/gparted-live-0.3.9-4.iso
        linux (loop)/live/vmlinuz1 boot=live  union=aufs
        initrd (loop)/live/initrd1.img
}

But when I boot this option it fails. The kernels tries to boot and then fails after several retries with this message:

    "unable to find medium containing the live file"

Which boot entry should I use to be able to boot directly from the iso file using grub2?

Re: [SOLVED] Boot directly from iso file on usb stick

GParted Live 0.3.9-4 is very old if that version number is correct.  We highly recommend that you use the latest version (currently 0.11.0-7).

Also, check the Live HD web page.  At one time GParted Live had the number "1" appended (e.g., vmlinuz1), but no longer.

Thank you, Using a newer version and following the remakrs on the Live HD page worked for me.

Re: [SOLVED] Boot directly from iso file on usb stick

I got a problem trying to configure 0.11.0-7 from debian wheezy:

menuentry "Gparted Live" {
   set root=(hd0,8)
   set isofile="/ronoaldo/gparted/isos/gparted-0.11.0-7.iso"
   loopback loop $isofile
   linux (loop)/live/vmlinuz boot=live config union=aufs noswap noprompt vga=788 ip=frommedia toram=filesystem.squashfs findiso=$isofile
   initrd (loop)/live/initrd.img
}

"unable to read kernel header"
"you have to load kernel first"
