You seem to have your root filesystem on a disk plugged into the sixth IDE controller. Unfortunately the GRUB boot loader only supports up to four IDE controllers. I've filed this upstream: https://savannah.gnu.org/bugs/index.php?19381
Perhaps you can work around this by plugging the disk into a different controller? ** Changed in: grub (Ubuntu) Sourcepackagename: ubiquity => grub Importance: Undecided => Medium Status: Unconfirmed => Confirmed -- Install failed https://launchpad.net/bugs/94642 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
