Upgrading from Vista home premium to win 7 hoe premium from DVD ex Digital river on gigabyte VM900m; core 2 duo 2.13GHz 2GB ram; Western digital 250GB HD. Got as far as "Expanding Windows files ...100% the error message "Computer encountered unexpected error... To install windows press OK to restart computer and reinstall windows" The computer then reboots, loads Windows 7 (new logo) a essage that says "setup is starting services" then the error message comes back. I can get into BIOS to change boot priority but the computer just ignores this and goes through the same sequence. At the point of "to boot from CD/DVD press any key" my keyboard is deactivated and i cannot make a choice and the sae sequence occurs. I cannot break the sequence - I have push every key, disconnected every external device including HDMI screen, but nothing stops the loop. Any ideas? Auswoolf
