When I use the msconfig there is only windows 7 available. The Ubuntu boot option is not there. When I try Easiest of all is this:
[windows key]+[Pause/break] to bring up system panel,
then click Advanced system settings,
Advanced Tab,
Startup and Recovery "Settings" button.
From here you can remove OSs and so on.

it gives me the choice to choose the default OS, but I can't remove the Ubuntu option.
