Update: I recreated the Dell and Windows partitions then restored the contents from a backup. The disc contained only sda1 and sda2 (values identical to the fdisk output above) with the remainder of the drive unallocated. I tried installing again as above.
The disk partitioning app failed to do what I expected. Its only suggestion was to try to shrink sda2 to fit in a small Maverick install in the free space in it. It totally ignored the 247GB of contiguous unallocated space following sda2. -- Maverick installer lost Windows partitions https://bugs.launchpad.net/bugs/659106 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
