very common problem. to prepare installation of windows xp. you have to change some of your bios settings. again being very general. during boot up, go to your bios and there is setting under your peripherials / hard drive. change it from SATA to something like Legacy.

Once you change that, it will recognize your hard drive during installation.

Do some more research, that way you get more specific information about your system/the whole process.


p.s Installing Windows XP may void your warranty. check that with your provider also.
