Welcome to the Community Forums.
You can try forcing Windows 8 to go to advance boot by turning it on/ off 2-3 times. Soon as you feel that Windows is starting, press and hold down the power button until it turns off. Tunr it back on and do the same process until a new prompt shows offering advance repair.
Another option is downloading a Windows 8 ISO image and boot from there. Follow the usual prompt until message box "Install Now" shows and look for the "Repair " option below to launch the advance options to troubleshoot.
Last advise if the above fail is to remove the harddrive and slave it on another pc or enclosure to back up your data.
I hope this helps answer your query.
