I can not get 12.04 or 12.1 to run on this PC since replacing the MB and installing Win 7. In fact after replacing the MB and running XP , Ubuntu wouldn't run but did see my second HDD, in Win 7 it doesn't. I have a 775Dual-VSTA MB, 2.8 dual core Intell PCU, an
ATI Radeon HD 5450 video card, 2gigs of memory, high definition audio card. I also have a Brother printer connected. Maybe I should unplug it and try again. Thanks for your help.
