Lenovo ideapad bought new 8/15/2016 windows 10. I was using it a couple days ago and when I tried to shut it down it took a long time so I manually pushed the power button. It usually goes off in twenty seconds. Next day I powered it up and, after a very long pause, it came on to a blue screen that said your computer needs to be repaired and boot missing and error 0xc0000034. I failed to make a recovery cd so I have no way to access the repair function. Am I screwed? Can anyone give me some idea how to get this laptop going again?
