It is never a good thing to power off the computer manually but under normal circumstances it shouldn't have prevented it from booting unless you did something else.  You need to hold the right shift key down before the splash for the grub to appear.  If your boot sector is corrupted here is a possible fix.

Boot the computer from any Live Disk.  (It does not have to be the same OS that you have installed.)  Open a terminal and type:

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt update
sudo apt install -y boot-repair && boot-repair

Click the “Recommended repair” button after it finishes analyzing the situation.  When the repair is finished copy the URL
(paste.ubuntu.com/XXXXX) that appeared on a piece of paper and reboot to check if you have recovered access to your OS.
If the repair did not succeed, indicate the URL to the people who help you by email or forum.

WARNING:  The default settings are the ones used by the “Recommended repair”.  Don’t modify them before creating a bootable URL and asking for advice on Ubuntu Forums “Absolute Beginners” section or “Installation and Upgrades”.

Hello,

 I have been running Ubuntu Desktop LTS 18.04 on my laptop for a few months, and today it won't boot properly. I wanted to know if you guys could help me out.

 It happened when I restarted my computer using the command prompt, but it took too long, so I powered it off manually. After that, the Ubuntu loading screen comes up, but it doesn't finish loading. I have tried holding down shift while it starts up to get GRUB to show up, but it just continues on with the stupid Ubuntu loading screen.

 I have now booted into my Ubuntu Desktop LTS 16.04 live disk, but I'm trying to figure out how to recover it, because I am tired of this screwing up and me having to reformat the disk, starting me all over again.

Thanks,

Eli D.

Interesting.  So why did you edit the file in the first place?  Did
the boot repair allow you to boot into your OS?

So it turns out that if you edit (and create) the file "/etc/lightdm/lightdm.conf" and put the text: "allow-guest=true", it brings the desktop environment (and the rest of the operating system) to a screeching halt.

I use Ubuntu Unity on Ubuntu 18.04. I didn't like the new stuff the came out with on 18.04, so I installed Ubuntu-unity.
