I just booted 12.04 for installation from USB-stick. But there is a problem with the display.
After boot I see a rectangle on the lower left corner of the screen, after a while I see "Ubuntu 12.04 ..." loading from USB-Stick, the Ubuntu-Desktop starts fine, clicking on Ubuntu-Install seems to work ... till identification, then Installation-window closed and ... nothing more happens.
So I want to try Installation direct from the Menu at the beginning - before Ubuntu-12.04-loading. Butt I cannot see any menus at that time.
I think there is an graphic-problem?
How can I get the installation by menus, how would the Installation via Desktop going to work?
EDIT: ... the point is, that I cannot see the "menu" with "Try Ubuntu" etc.
I now tried to make a blind input F6 etc. The result is the Ubuntu-Desktop with the Install-icon ... that breaks after input of the identity :-(
I think, that there is a graphic-problem before initiating the start-up-menu ...
