I don't get the TRY UBUNTU option

I don't get the TRY UBUNTU option

I've tried all the options, I think. I'm on Windows 7, 64-bit. The first
option I tried was to burn the Desktop installer 12.04.02 32-bit onto CD.
When I boot from it, I don't get the Try Ubuntu option. I only get the
install option + others such as recovery, test memory, etc. Then I tried
the alternate 12.04.02 i386. Then I burned the desktop installer 12.04.02
64-bit to a dvd. Same thing. No Try option. Does anyone know why?
Thanks!
