if you are in SATA/AHCI/RAID, you need drivers on a good old floppy for XP to install(hit F6 during the install).
To get by this, you can slipstream
drivers to a burned cd with windows], but it does not always work.
IDE mode in the bios works as well, but will loose some features(NCQ, trim for SSD's ect). If you are just running a basic setup without raid or anything fancy, this may be the best option.
