Your report is completely unclear to what has happened on your computer; I'm left with the distinct impression that your system booted just fine.
In particular I have no idea what the "usual recovery options" are - since we completely rewrote those in 10.04 and if you're seeing something you'd normally expect, then you can't be running 10.04 ;-)
