You need one of two things; either a free partition on your current hard drive or a second hard drive.
If you have either of the cases above, simply put the Linux installation disk into your DVD/CD drive and install on the second hard drive or in the free partition.
If you have neither and do not want to buy a second hard drive, then you must buy software that will repartition your hard drive without lost, and then install Linux in the newly created partition.
Not considering either of the above solutions, you must reinstall your operating system, deleting the current partition and creating two partitions during the installation.
Install Linux in one partition. Install it first, then reinstall XP.
Be sure to install the motherboard drivers and utilities from the motherboard CD.
When completed, go to www.microsoft.com and let that site update your WINDOWS data.
