I managed to install Ubuntu onto my Intel Matrix RAID 0 using the alternative install disk after some further experimentation.
Using Gparted I created a new MSDOS / MBR partition table and formatted the drives. Using an MBR partition table is important because GPT partition tables require the kpartx application to map the partitions. To my knowledge kpartx is not pre-installed in the altenative installation disk and programs cannot be installed on the fly like they can with live disks. I then booted into the alternative installation disk and manually formatted partitions as usual. Thankfully the alternative installer does not seem to have any problem installing GRUB. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/686859 Title: "Bootloader install failed" cannot be closed -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
