This is a 'Feature' of Win XP. It's designed not to boot in a system it was not installed on. This is another form of anti piracy methods and security so someone else can't steal your info as easily as before.

There are 2 solutions I can think of.
1. Boot to the Windows disk and run Fixboot command from the repair console.
Recovery console
(this usually works)


2. If you still have the old system- re install the HDD and boot it and remove all the drivers in the device manager - turn off and move to new machine.

-Also you can try running the sysprep command in the old machine (advanced read the docs) How to use the Sysprep tool to automate successful deployment of Windows XP

You are better off doing a repair installation when you change a motherboard.

Full details on doing this from Microsoft... Perform a Repair Installation

Edit: You will not loose any of your data when you do a repair install either...

Note-
You can not do a repair (install over old system) if you have a Windows XP SP1 disk but the hard drive has been upgraded to XP SP2.

Repair is an option, but I advise you do it at your own risk. Depending on how different the system is, your computer could essentially become incapacitated. I personally have seen issues ranging from random restarts and monitors that do not turn on with clients. (not being able to see what you are doing makes it really hard to fix the problem)
If it is successful, I would suggest that you uninstall all drivers which are not hardware specific, restart and install the correct ones to prevent many of these problems. In my opinion, I would try this first. Windows will attempt to find the drivers on the next boot, which will allow for plug and play, which may let you boot Windows in non-safe mode.

I do not know if MS designed there OS with security in mind in this aspect, it is a common deed to have a flaw, then right before release figure out how it could be perceived as a good thing and pretend that's why it's there.
Windows does have a hardware setup stage during installation, which is why it does not boot properly with drivers and what-not in another machine.
