please give us more info (do not cut/edit the output).

Layout of both disks:
# fdisk -l /dev/sda
# fdisk -l /dev/sdb

For F12 (the one you try to preupgrade) log in and get an output:
# cat /etc/fstab
For F13 (the one you already preupgrade-ed) log in and get an output:
# cat /etc/fstab

By the way:
when you run preupgrade the next time (2nd, 3rd, etc) you are asked whether
you want to continue from the point of previous stop/failure point or from
the very beginning.
IMPORTANT: I would advise you to stop changing anything on your machine (disk
layout, swaps, /etc/fstab, etc) so that the data I ask you for above is true
from that point on and we can help you !
