I am trying to add an ISO (alternate distro of ubuntu ) to my GRUB .

This is the output of fdisk -l:

grub.cfg

menuentry "Ubuntu Alternate Install 10.10 32bit" {
 loopback loop (hd0,0)/boot/ubuntu-10.10-alternate-i386.iso
 linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/boot/ubuntu-10.10-alternate-i386.iso noprompt nomodeset 
 initrd (loop)/casper/initrd.lz
}

I added an entry to 40_custom file like this and did a sudo grub-update.

menuentry "Ubuntu Alternate Install 10.10 32bit" {
 loopback loop (hd0,1)/boot/ubuntu-10.10-alternate-i386.iso
 linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/boot/ubuntu-10.10-alternate-i386.iso noprompt nomodeset 
 initrd (loop)/casper/initrd.lz

But I am getting this File Not Found , You need to load kernel etc when I chose this option from the GRUB Menu . Where am I going wrong

  • Did you try giving your new menuentry a different name than the one in grub.cfg?

According to http://pendrivelinux.com/downloads/multibootlinux/grub.cfg you have to leave out the (hd0,1):

menuentry "Ubuntu 10.10 Desktop ISO" {
 loopback loop /ubuntu.iso
 linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/ubuntu.iso noeject noprompt splash --
 initrd (loop)/casper/initrd.lz
}

This can be found at Boot Multiple ISO from USB via Grub2 unsing Linux. Probably you should check out this page and compare these steps with your setup.

Good luck!

I tried to get a community wiki going on these topics, I'll just copy my answer from here below. I hope this helps!


So I have created a simple file 39_iso inside /etc/grub.d/ for loading my ISO's. I have a copy of Ubuntu 10.10, Clonezilla, and SystemRescueCD. My entries make sure the ISO file is available inside /iso/ before adding the menu entry. For example Clonezilla will load into memory, so I can clone my hard drive whenever I want!

Ubuntu 10.10:

if test -e /iso/ubuntu-10.10-desktop-amd64.iso ; then
  isofile="/iso/ubuntu-10.10-desktop-amd64.iso"
  echo "Found Ubuntu 10.10 (x64) ISO: ${isofile}" >&2
  cat << EOF

  menuentry "Ubuntu 10.10 (x64) ISO"
  {
    loopback loop $isofile
    linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=$isofile
    initrd (loop)/casper/initrd.lz
  }
EOF
fi

Clonezilla:

if test -e /iso/clonezilla-live-1.2.6-24-amd64.iso ; then
  isofile="/iso/clonezilla-live-1.2.6-24-amd64.iso"
  echo "Found Clonezilla Live ISO: ${isofile}" >&2
  cat << EOF

  menuentry "Clonezilla Live 1.2.6-24-amd64 ISO"
  {
    loopback loop $isofile
    linux (loop)/live/vmlinuz boot=live live-config union=aufs nolocales noprompt ocs_lang="en_US.UTF-8" ocs_live_keymap="NONE" vga=791 ip=frommedia toram=filesystem.squashfs findiso=$isofile
    initrd (loop)/live/initrd.img
  }
EOF
fi

SystemRescueCD

if test -e /iso/systemrescuecd-x86-1.6.2.iso ; then
  isofile="/iso/systemrescuecd-x86-1.6.2.iso"
  echo "Found SystemRescueCD ISO: ${isofile}" >&2
  cat << EOF

  menuentry "SystemRescueCD 1.6.2 (x64) ISO"
  {
    loopback loop $isofile
    linux (loop)/isolinux/rescue64 setkmap=us docache isoloop=$isofile
    initrd (loop)/isolinux/initram.igz
  }
EOF
fi

I've also fixed how GRUB names Windows 7 as Windows 7 (loader) to something nicer like Windows 7 Professional (x64):

if [ "${LONGNAME}" = "Windows 7 (loader)" ] ; then
  LONGNAME="Windows 7 Professional (x64)"
elif [ -z "${LONGNAME}" ] ; then
  LONGNAME="${LABEL}"
fi

It replaced a section such as the following:

if [ -z "${LONGNAME}" ] ; then
  LONGNAME="${LABEL}"
fi

Inside 30_os-proper of GRUB
