Hi, dual booting shouldn't be a problem because your array should be able to run multiple partitions, however I have to ask exactly why you want to configure RAID 0?
A few facts and misconceptions about RAID may change your mind. In the end it is up to you, but I think you should at least know these things before proceeding. First off, RAID 0 offers pretty much no performance increase on basic usage, internet surfing, office productivity and gaming. It will offer increase in pure data throughput. So, if you are editing or managing huge files that are many gigabytes in size you will see a very nice performance increase. it also reduces the stability of your system. If one drive in the array fails then your whole system fails. Yes, for windows XP you will need a floppy disk because the installer is retarded and can only read RAID controller drivers from a floppy disk. The other option is to slipstream drivers in a SP2 installer disk, which can be found how to via google.
In my opinion its not really worth it for end users to run RAID unless its application specific, like video or audio editing or anything else that would make you manipulate lots of data at once.
