That was exactly what I was doing - the idea was to keep the original as
an (untouched) master and do the upgrade on the copy. That way, if it
worked, I could use the original, and if it didn't I'd still have it to
put back in place. After the dd I had only one disk connected at a
time.
If the dd should have copied the mbr sector, then there *must* have been
a geometry problem. I think what I'll do now is connect the second
drive also, manually make partitions, copy over the data from the
master, install a boot loader using either grub-install or grub, and try
to boot that way. THEN if that works I can upgrade.
I think this has been covered before, but any suggestions for how to
copy, on a partition-by-partition basis, from one drive to another?
Would that be a good problem for mondo? And would that take symbolic
links into account?
