All excellent questions which I would have thought deserved at least
a bit of text in the release notes rather than just firing a barrel
full of acronyms at you :-).

Basically though, if you are using an existing disk that is
already partitioned, you don't have a GPT disk. Apparently
GPT is a brand new partitioning scheme that breaks free of
the old DOS scheme (and is necessary to take advantage of
the disks bigger than 2TB that are getting common these days).

If you actually needed a bios boot partition and didn't make
one, your system would not boot (I know from experience :-).
