booted the machine, installed Ubuntu, and without creating any partitions. I
just wiped all the old partitions out and used the entire drive for Ubuntu --
so the partition manager said at install.

from Quirky to see what partitions are on the drive, and sda1, sda5, and sda2
are still on the partition.
You do strange things for fun. If you install a GNU/Linux distro, you will
need partitions. (you need those in any operating system, they may be called
something else in their lingo however) There is no option to not create
partitions. your choices are automatically create partitions or manually
create partitions.
