I just thought of one more awful thing which has happened to me
on a number of occasions, way embarrassingly too many times.

You don't happen to have a floppy disk in the floppy drive or possibly
a non-bootable CD in the CD drive do you.   That is where I see 
that message most often.  If you tried to install using the two 
floppies, for example and didn't pull the second one out before
rebooting, it would do that.  The same would be true if you put
one of the other CDs in the set to load some things.

I'm still guessing something to do with the MBRs and boot blocks
and whatever you called the 'a' partition in the slice, etc though.
