Hmmm... I wonder why you got the BSOD when you plugged it into your new machine?
Congrats that you were able to recover your data.
The hard drive from the laptop was a complete XP booting operating system which confused the new computer when I plugged it in.
I was essentially trying to boot and already booted system.
Like trying to start your heart when it was already started. 
Seems like having a Linux computer lying around comes in handy.
Plugging in an external drive won't change the boot order, I've done what you described (plug in external, bootable drive) many times on XP machines without incident, never required a Linux machine. I've also attached drives like that internally with no issues.
I can think of a scenario that might cause confusion and that would be if you plugged the external drive in BEFORE booting the machine AND your BIOS settings were configured to boot from a USB device first.

When you install the OS, whatever it is, it sets it up to run with all the current hardware. When you pull the drive off and plug it into a different machine and try to boot up, all the drivers and settings are expecting to see the hardware they were intended for.
So when it is loading the drivers and it gets to a completely different item, such as chipset, mass storage devices and so on, it stops dead in its tracks and cannot continue loading because the item it is looking for is not present.
Hmm- my OS detects the hardware on each boot, and with the exception of *some* graphics devices, I can pull the hard drive out and put it in another computer and it will boot just fine- though it might dump you to a text mode screen if a graphics driver is missing, but it won't crash. The only caveat is the boot device order and terminology, though that is easily editable.
I have found that anything after Win 98 is a nightmare to move the hard drive from one machine to another, especially XP and later. Unless the chipset is identical or very close, I always get a BSOD - inaccessible boot device. I have found that if I can find a mboard with the same chipset, I can get it to boot and then re-configure the hardware drivers, but if you go from VIA to SiS for example, it will BSOD.
I think a lot of this is to prevent people from doing a complete install on one machine and then cloning it to various others.

The XP HD was a 32bit system, but the New HP is a 64bit and I plugged it in to a running system. Except for the matter of dislodging the video card in the Linux box while correcting a problem. I always need an excuse to tear down a system.
I'm the Demolition Man.
Back to rebuilding the DW's bathroom. See, I told you so, tear down.

BIOS-provided physical RAM map:
The whole thing is way to long (and boring) to post, but it detects the bios first, then APCI, Northbridge,CPU, PCI, USB, then detects pretty much everything else (graphics last on my install).
It can be set to not go through all of that, but it only takes a few extra seconds to boot, so I leave it alone.
The line: root=/dev/sda1 is the one that might have to be edited for the physical disk, if it isn't sda1, but that's easy on boot.

Chris,
That's probably why it works for you.
You are running a non-windows platform!
I only have one Linux based computer. That is my Asus EEE. Great little machine and never any OS problems either!
All the computers I have tried swapping HD's around in were running Windows of some sort. MS has their way of throwing wrenches into peoples activities.
I actually just managed to salvage one yesterday and today. My webserver has been dead for some time now. I replaced the mboard with another with the same brand chipset and got it going without an OS reinstall.
So now I have my webserver back up but I'm having a miserable time trying to make it visible on the net. My ISP is always doing something to block people from running a website.
