|Let's make some assumptions.|
1. you are attempting to do a clean install of XP
2. The system you are attempting to install XP on is compatible with that operating system and meets/exceeds the minimum requirements.
3. You are attempting this install using a genuine commercially produced install CD
On second thought let's not assume anything. You know what they say.... you make an assout of u and me
Please provide a full description of your system and a detailed description of what you are attempting and the exact point in the process the problem arises plus the precise error message.
