OK, managed to fix it following this advice: http://leisurehours.wordpress.com/2010/03/15/partition-table-entries- are-not-in-disk-order-problem/
That required some repair on the GRUB command line, set root and all that, then got my system to boot into Ubuntu and had to do both update- grub and grub install /dev/sda. I now have this: Warning: extended partition does not start at a cylinder boundary. DOS and Linux will interpret the contents differently. # partition table of /dev/sda unit: sectors /dev/sda1 : start= 2048, size= 2457600, Id= 7, bootable /dev/sda2 : start= 2459648, size=226342912, Id= 7 /dev/sda3 : start=228802560, size=238088192, Id= 5 /dev/sda4 : start=466890752, size= 21504368, Id= 7 /dev/sda5 : start=228804608, size=233887744, Id=83 /dev/sda6 : start=462696448, size= 4192256, Id=82 gparted now shows this as /dev/sda1 ntfs SYSTEM_DRV /dev/sda2 ntfs Windows7_OS /dev/sda3 extended /dev/sda5 ext4 / /dev/sda6 linux-swap /dev/sda4 ntfs Lenovo_Recovery So it seems like the issue was that sda3 started after sda4 and when these were put back in disk order, it works OK. It appears that gparted will leave the partition table in this state under some circumstances if you add/remove partitions (at one point this drive had four partitions under sda4 until I removed some unused partitions).
