It took some looking to find this description of the problem in the 

Some systems do stupid things based on what they find on the hard disk. 
Lenovo and IBM before them did this, for example.  Still do, in some 
cases.  It is not just a GPT thing, they did stupid things with MBR 
partitions also.  The idea that old systems can't boot from GPT is 
incorrect.  GPT has the PMBR, a backwards-compatible MBR booting 

Some systems require a system partition for the BIOS.

Given that this is a custom system, there might be some kind of security 
information stored on the drive.

If it were me, I would use gpart to look at the partitioning on the XP 
drive.  It is likely MBR, but the number, type, and size of partitions 
could be a clue.
