Get Out Of Vista And Into Xp Home

[MEDLAR]

I have a new Compaq Presario with ASUS P5LP-LE Motherboard and Intel 945G chipset. Vista was installed. I have swapped HDD and tried to load a clean copy of XP Home. Installation stops and Hex info appears on the screen. I have a feeling that something in the BIOS or chipset configuration is baulking me. Can anyone help, please.

delete the partition and start clean
