Wont turn on

every time I start windows 8 it gives me the blue screen of death And aftet that it automatically goes to windows auto repair but after a few minutes it cant find any problems. after that it takes me to a screen with three choices restart pc turn of and advance options. i tried to refresh my pc with the window 8, i have the iso put it in a flash drive and a cd, i tried the cd fail, flash drive fail keeps saying not varified. by the way my computer is a well used to be an hp windows 7 home premium. MY POINT is that could you guys figure out why it keeps telling me why it keeps saying not varified.

nevermind everuthing i used hp compact restoration to restore my computer its good. what sucks though is that now i have to start from scratch oh well at im just glad its working

 

I think you could have saved yourself some headache if you have installed Windows 8 to dual boot with Windows 7. With a dual boot, if Windows 8 fails, you can still fall back on Windows 7. Actually on my own pc, I have a quadruple boot set up. Two of the options are for Linux and two are for Windows.

Now that you have got Windows 8 working again, consider making a Hiren BootCD on a pendrive. This is a great tool which you can use when you cannot access your hard drive due to a Windows crash.
