Hello. My name is***** to JustAnswer. I'm reviewing your question now, and will post back with your reply momentarily.
Do you have a mac or do you use windows 7/8/10?
Is your computer a laptop or desktop. Please reply and i will guide you
where to look on your pc so we can get started.
We need to try a few things here first to narrow down how to get in so we can determine exactly what went wrong
and how to fix it.
Can you tell me if you can get this far?
Turn your Mac off by holding down the power button for a few seconds. Turn on your Mac and hold down the Command and R keys until you see the Apple logo. Then you should see a “Mac OS X Utilities” window. Select Disk Utility, click your OS X hard drive and select verify/repair disk.
