Apon boot up have a error mesage: Reboot and select proper boot device.
When I try and run the Refresh my PC off of my Windows 8 Install USB, I recieve error: The drive where windows in installed is locked. Unlocked the drive and try again.
I use the gigabyte z77x-ud3h-wb with intel rapid start and smart connect ith raid enabled, I was able to fix it by creating an unfavourable boot environment for windows 8, reset bios to optimized default and set boot environment to a setting that would guarantee a boot error, windows 8 would try to with. An error, reboot the system set bios setting to normal, and windows would boot and repair the errors, it takes a while but you would not need to reformat the system
