Have you tried a power shutdown to see what it does after the reboot.
A restart followed by a power shutdown when it gets to POST three times will invoke diagnostic mode where you should be able to access the advanced boot options.
From there, you can access system protection to use your restore points or from the Command Prompt by entering rstrui.exe
Which version of Win 10 are you using ?
EDIT - By POST I mean when you see the Windows logo.
