good staff took my pc a new motherboard and everything right ta. Start the PC and put the installation cd of windows 7, he says if I want to boot from cd and I say yes. Everything starts normally and I choose Windows 7 Ultimate x86. When I put the following appears this message "The computer was started using the windows disk enstalo. Remove the installation disc and restart your computer to boot windows normally. Then insert the installation disc and restart the upgrade."

Has begun No cd and then put countless times, always appears the same error!
