my problem is the following. I did a restore point but not from inside Windows 10, but from the automatic repair. It said it did it successfully, but when I restarted it came back to Automatic Screen and said that it can not start. Then in the command prompt, I did your suggestions about restoring baster boot record, even the option to delete it and re-create it. I received a message that it was done successfully. but after the restart, it starts and doesn't go past the Acer logo, ... Now it doesn't even go to Automatic repair anymore. Can you comment on this? Thank you very much in a advance.
