    Can I install windows XP, on a Software RAID??

    Also can you partition a hardware raid?

    Hardware RAIDs can be partitioned.

    Software RAIDs can't, at least those created by Apple's Disk Utility; and I think the Boot Camp Assistant utilizes Disk Utility.
    To get a partitioned software RAID, you have to partition your drives first and then build RAID sets out of those partitions.

    The next question would be whether Windoze can recognize Disk Utility RAIDs and I'm quite sure the answer is "no".

    Just search the MacRumors forums using google:

    I have tried to do this and so far I have not suceeded. So according to todays knowledge of this board I would say it is impossible to use OS X disk utility to build a Windows SW Raid0.

    I have also tried to build a Windows HW RAID0 with a Highpoint RR2642. That has also been unsatisfactory mainly because EFI does not recognize the RR BIOS consistently at boot point. If you do not use OS X and Windows only the RR Bios comes up every time biut that is pointless.

    As gugucom indicated, it won't work for OS X's software RAID. You'd either have to find a better eSATA controller + driver (FakeRAID card) than the RR2642 that was attempted, or skip to a true hardware RAID card.

    I'm not sure the details, but it seems to do with the GPT is implemented differently between OS X and Windows, so it can't interact. You need to use separate disks at a minimum (assuming attached to the logic board's SATA ports).
