Unless you want to dual boot with windows, the easiest thing to do is destroy the raid configuration in the bios utility, and install ubuntu on to the two seperate disks, setting up a pure software raid. Otherwise in dapper you should be able to get it working by installing the dmraid package. See https://help.ubuntu.com/community/FakeRaidHowto for more information.
