====== Multiboot Stick ======

howto create a bootable livesystem usb stick, which boots iso images with grub2

  * boot linux (debian/ubuntu/.. running grub2)
  * become root (su / sudo -i)
  * attach usb stick
  * find device of the stick

  fdisk -l

  *replace sdX by the usbstick device you found in the next steps!

  * mount stick

  mkdir /mnt/usb
  mount /dev/sdX1 /mnt/usb

  * install grub to stick:

  grub-install --force --no-floppy --root-directory=/mnt/usb /dev/sdX

  * edit grub.cfg config to match your iso files - 

  edit /mnt/usb/boot/grub/grub.cfg

  * example grub.cgf:

  ###   MultiBootStick
  #     grub2 direct ISO boot config
  
  menuentry "ubuntustudio-12.04-dvd-amd64" { 
      set isofile="/iso/ubuntustudio-12.04-dvd-amd64.iso"
      loopback loop $isofile 
      linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=$isofile noeject noprompt -- 
      initrd (loop)/casper/initrd.lz
  }


reboot from stick - have fun :)
