Yesterday, I received my laptop Dell Inspiron and I did Ubuntu installing. It comes with Ubuntu. When I finished, in terminal, I did this commands: sudo apt-get update && sudo apt-get upgrade. A long time after, the upgrade finished. To test, I restarted my laptop and a purple screen appears. Just this. I couldn't login. I needed to go back to the factory installation. Can someone help me? I am new in Ubuntu. Thanks
Do you know how to return to factory mode? Because the only method that can fix it is to download the ubuntu 18 or 19 .iso, which is free from this page:
If you have other computers with windows system you have to do the following. Then with the rufus program you throw an EMPTY USB with the ubuntu iso and when finished, you insert this USB to your device and if it starts by default, if not, you have to enter the bios to start from the USB. Link to download rufus:

Also if you have just bought it you should call the store or the supplier and explain that after an update the computer failed.
