Today my brothers wanted to play on their laptop (Lenovo). After 30 seconds of loading, error on blue background appears and it say "Cannot run system. We are looking for reasons" - and after it, restarts. After the restart - black screen appears and lasts for 4 hours (and still can't start!!!) What should i do now? Download illegaly windows and reinstall it? I can only open BIOS. System's recovery tool doesn't work. It is Phoenix Bios. What tools do you recommend? Help!
