What I recommend is the following: a) Download and install Macrium Reflect (MR) b) Use the option to create a boot USB stick or CD c) Boot your PC from the MR media -- it will take a while, so be patient! d) If needed, select the option to repair the Windows Boot
The PC should now reboot without problems. IF it still has problems, there are other issues at play.
