The last error message means what it says...
Probably fixable by copying /usr/mdec/boot to /boot (the install should
do this....)

The upgrade code will assume that wd0a is the root partition, mount it,
look for /etc/fstab, mount all the mentioned partitions, the install
the sets over that set of filesystems [1].

If your disk didn't look like that, the 'upgrade' will not DTRT.
You will probably need to boot the install media and exit (^C) to a shell
to find out what actually happened.  Only then can a fix be sorted.

[1] A particularly useful feature if the install kernel numbers the
disks differently from the one the system had been running - but at least
it wont do an 'rm -rf /tmp' after mounting the wrong disk partition on /tmp.
