Hi, I've just finished putting together my new build (finally!) and im trying to install vista. I had an error the first time i ran the installation because of ram settings but now whenever i try to run the install again it comes up with "BOOTMGR is missing". I try to boot from the DVD and it comes up with "press any key to boot from DVD" so i press keys and it ignores it and goes to the bootmgr error. Could it be because ive got a wireless keyboard that its not detecting it or is it something else?
