    Many thanks for this: useful reference for me.

    I solved this problem by re-running and choosing /dev/hda on the
second machine. It then rebooted without any problem. For the
first machine, the one on which I had chosen /boot, I used a Debian
install disc to enter rescue mode, and ran upgrade-from-grub-legacy,
choosing /dev/sda this time. It then rebooted fine.

    Sorry for panicking without having tried the saner approaches first.
