Googling suggests that the partition table is munged.  It is possible that
booting again will magically fix it; at least I think that's how it is
supposed to work.  I don't actually know what MediaDirect /is/ yet.  It
seems to be built into the firmware and into the BIOS, and probably has
something to do with preventing you from using your computer for anything
Big Entertainment doesn't want you to do.

Recreating the partition table may fix it.  Dumping the partition table
might be informative.  It may also be necessary to re-install Grub.
Pressing the button again will probably hose it again.  You might want to
cut that button off the keyboard.  More googling is indicated.
