Stuck on black screen asking for login and password
So I tried to update my machine and then a power outage occurred , I googled it and searched around and it told me to hold shift, I got this special menu and clicked advanced options or something (kinda like a system restore) and now it's on a black screen asking for a login? Even though I know my user name and password but it's saying it's incorrect?

Option 1: Use boot repair.
Ubuntu was unable to boot and there is this fancy tool for such problems: boot repair. This should allow you to boot into Ubuntu again.
Option 2: Reinstall Ubuntu (you are likely to keep your personal files in the Home folder!
You can try writing either a new disk image or live USB with the version of Ubuntu you like, or use the same liveusb/DVDROM you used before and run the distribution update again. You will have the option to keep your home folder (if the hard disk is not corrupt.)
