Hello My name is Ron and I'm a new guy here.
I installed Ubuntu 18.04 LTS on my desktop Intel Core i3 9100, 12 GB RAM, 256 GB SSD
When I run Ubuntu, It keep loading and loading like forever.
I need some help
Thanks

We need more information to help us help you.

When did you create this installation?

Did it ever work correctly?

What are the last things seen on screen before you see these loading messages?

What exactly are the loading messages?

Is it an ordinary SSD, or an NVME SSD?

Why did you choose to install a 30 month old release instead of the most recent LTS release? Your Coffee Lake CPU/IGP may well be just a little too new for support by the 30 month old version. The best and likely easiest fix may well be to replace 18.02 with 20.02.

And ...
- is it a dual-boot with Windows (8, 10, which), or it is only Linux ?.
- do you know how to get into the "BIOS" screens ?.
