Hi All,
When I try to load windows XP to a Dell Optiplex 745 machine I get the following error:

\windows\system32\halmacpi.dll

Status: 0xc000098

Windows failed to load because the HAL is missing or corrupt

I have tried different windows XP discs and same error.
I had replaced the HDD, and I get the same error with the new HDD.
I had replaced the RAM and same error.

Has anyone seen this issue before?. las thing to do here is replace the Mboad.

Hold up.
Before you do that read this piece: http://blogcritics.org/archives/2009/03/05/020234.php

Boot from your CD and follow the directions below to start Recovery Console.

Insert the Setup compact disc (CD) and restart the computer. If prompted, select any options required to boot from the CD.
When the text-based part of Setup begins, follow the prompts; choose the repair or recover option by pressing R.

If you have a dual-boot or multiple-boot system, choose the installation that you need to access from the Recovery Console.
When prompted, type the Administrator password. (if you didn't create one try pressing enter).

At the system prompt, type chkdsk /r
