Sorry, I read the thread very fastly.
Can you give us any clue (full view) about your disklabel ? Especially, what
you own as sd{x}a as a range ? Otherwise I think difficult to say or guess what
you really can/can't do.. what you have at 0 - 2048 position..
Second, worst as it could be you can pax everything important and restore your
partitions on a good system.
Third, sometimes happened to me to be on a stick and to have s disk root
unaccessible for a *foo reason*.. I then copy machine (data copy) my stick to
an external disk to have the upgrade running smoothly then. Never said.
