Boot XP from USB - Help Please

I have a hard drive lifted from a 150 with Windows XP Home installed on it. I was hoping to exchange it for the SSD in my 110 but that proved impossible.

I have put the drive into an external USB drive caddy and it operates correctly and reads.

If I connect this external drive and boot up pressing F12 I can choose to boot from the USB drive.

It finds Windows and starts to boot.

I then get a message briefly displayed saying that there is a Windows Error and it is closing to protect the system.

Does anyone understand what is happening and whether there is a simplish solution?

I suspect that there is a drive conflict in that the SSD memory is referred to as C: and the USB drive as D: or whatever and at some point in loading, Windows is confused as to the drive it is booting from.

Does that make any sense?

I have run Checkfile on the drive using my Vista laptop and no problems were found. I turned off options to correct system files and so nothing has been changed on this drive.

 

I have 2 external usb HD and I would like to use them to boot XP from them, leaving Linpus Lite on the 8 Gb SSD... I saw in other forums that it can be done... but no one says how. How can this be accomplished?

 

I've tried this approach and have gotten so far as to get setup to boot from the usb drive. However, when selecting which partition to install to, setup needs a windows partition on the ssd, since it still remains the first disk, dispite not being first in boot order.

Anyone have any idea how to get around this?
