I have not encountered this problem before but maybe this can help you. However, I have to confirm if these few things is happening to your pc:
1. Does the 'laptop logo' show on boot?
2. Does the spinning thing show on boot?
3. What is your laptop? (acer? dell?)
If the logo AND the spinning thing show, you can hard shut down when the spinning shows
1. Once you see the spinning thing, press on your power button to hard shut down
2. On the pc again and do step one again
3. repeat a few times until you see the 'Automatic Repair' screen. or the diagnosing pc screen
4. After a while the 'automatic repair screen' should show
5. Then click on advanced > troubleshooting > system restore
And finally restore the system -- It should fix your issue! (post some pictures so i know what is goign on)
