How to boot a win XP partition on an external usb hard drive

I have cloned my multi boot (11.0, 10.3 and win XP using grub) desktop hard
drive to an external usb drive and would like to boot the win XP partition
from a laptop which at the moment is set up to dual boot 11.0 and Vista.

I’ve remapped the hard drives in the laptop menu.lst file and tried every
combination of instructions which I can think of in this file to no avail.
I’ve also tried setting up the boot loader using Yast with equal success.
If anyone has any experience with such a setup could you please post your
menu.lst file. Thanks in advance,

Allan

XP will not boot from a USB hdd without modifying installation files before you do the install. There is no way to clone from a internal to a usb hdd and have it boot. It is not a problem with GRUB but MS did not program their OS’s for booting from USB hdd.

Nor will XP boot when you move it from one comp to a totally different comp without doing a repair install and activating it.

If you want to have XP alongside your existing setup, you will probably have more success virtualising it.

think one second about this: even if it were possible to boot XP from
a USB drive, the desktop might have had a nVidia graphics card while
the laptop an Intel graphic chip…

therefore just that one piece of dissimilar hardware could make it
impossible to boot…

Thanks to everyone who replied. My laptop allows booting from usb and I
came tantalizingly close to having XP load that way. It got as far as
showing the initial Windows screen before dying. I was hoping that grub
would be able to overcome that problem.

How should GRUB do that?

GRUB did his job sucessfully the moment XP started booting.
