Dear list,

I have live usb system where I already have debian, puppy, ubuntu etc.....
I like to boot backtrack iso from this usb drive.

Here is the entry for BT5 I have added at grub.cfg

```````````````````````
menuentry "BT-5" {
loopback loop /BT5-KDE-64.iso
linux (loop)/casper/vmlinuz BOOT=casper boot=casper iso-scan/filename=/BT5-KDE-64.iso nopersistent noprompt --
initrd (loop)/casper/initrd.gz
}
```````````````````````````

but grub throws errors as

```````````````````````````
error:can't read linux header
error:you need to load linux kernel first
`````````````````````````

Any idea what is missing here ? I have already checked the iso by mounting as loop device
and confirmed the presence of casper/vmlinuz and casper/initrd.gz. So why is it complaining ?

Thanks

Why would you not ask on backtrack forums? It is related to there mess.
Or even better GOOGLE your issue, I got quite a few including guides to
multi boot on USB with BT.

Hint there error is pretty obvious if you read what its telling you ;)

I got backtrack 5 iso to boot on multiboot grub2 usb drive. I got the
info from a backtrack help forum. This trick is to extract the "casper"
directory, placing it in the root of the usb drive (not in any other
directory).

My menuentry is as follows:

menuentry "BackTrack 5 32 bit" {
linux /casper/vmlinuz BOOT=casper boot=casper nopersistent rw vga=0x317
--
initrd /casper/initrd.gz
}

DO NOT use (loop) in the above menu -- it won't work (and there is no
loopback).

You will boot into a terminal. Then you shout enter "start networking"
command (without quotation marks). After this you enter "startx" command
and you should be presented with a BackTrack 5 gui environment
