Cannot install from USB stick

[EOC2611P]

Hi,
      i am trying to install the latest version of PFSense from a USB stick to an old IBM 8320 (Windows XP), but i am getting many error's message, can please anyone give me some advice on how to fix this problem?….maybe i should use a previous version of PFSense?
Thanks

I found a workaround by removing the hard disk of a broken pc where PFSense was installed and restarted using it inside a working pc.
If however someone knows an answer to the original question, it will still be appreciated.
