No. when you created your partitions, and you finish partitioningyour second one, you didn't move the highlighted line back up to the C drive when it ask you to install xp (everybody have done this one before as it is real easy to do if you aren't looking for it) Reformat and repartition and make sure you install xp on C.
that said. you should 1 partition your OS and the other your data storage. you can make your second partition be your my document folder
