[core] revert to having the ESP as the last partition

* This is to avoid Microsoft's appalling refresh of the partition layout,
  which can result in partitions not being assigned a volume GUID.
* Mostly reverts a change that was applied in 1c39a80d72.
* Also add some more enum output and bail if we can't get a logical drive.
* Closes #1351
