Does it show the partitions correctly to choose from on the XP Drive selection menu? If not you may need to add SATA controllers which are too modern to be in the XP installer:
SATA Drivers - Load in Windows XP Setup on Dual Boot
SATA Drivers - Slipstream into Windows XP CD
It's also best to use an XP installer for your version with SP3.
If you don't want to go to the trouble of inserting the SATA controller drivers or troubleshooting, try virtualizing XP in Win7 using XP Mode in Ultimate or Pro, Virtual Box, Virtual Player or VMWare.
