Followup: Presently there is no out of the box support for BIOS enabled software RAID such as the many that come with NVidia, Intel or Highpoint Chipsets. This can be a turn-off for power users wishing to dual-boot WindowsXP and Ubuntu.
Dual booting is easily performed, and the team has done an incredible job on a variety of systems, still I feel this area is severely lacking. In order to even get Ubuntu to see the drive you have to install DMRaid, which is in the universe of repositories, once you enable it. Subsequently with installing ntfs-tools I was able to successfully resize the partition using a combination of ntfs-resize & fdisk. Now Ubuntu installer is able to see the free space, but the installation fails, though it successfully creates the partitions it fails 15% way through "Installing System" with "Failed to create a file system":"Detecting Filesystems". -- Intel RAID controller doesn't work https://launchpad.net/bugs/57860 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
