I recently buy a dell inspiron 3480, in which ubuntu 18.04 lts was installed by default. Then I installed windows 10 “sucesfully”. But after a while, I had an issue with 100% disck usage by windows process, So I decided to go back to ubuntu. However, I am having trouble with the installation of ubuntu, founding this info https://certification.ubuntu.com/hardware/201810-26530, in which you can find that “Standard images of Ubuntu may not work at all on the system or may not work well”.
I installed ubuntu normally from usb, but now, the computer does not boot at all.
My final objective is to make a dual boot in this laptop. Any advices on this issue? Thanks in advance.
Update: in this link I store some pictures of the bios setup of my laptop: https://github.com/nmolanog/dell_3480_bios
The error message is : "No boot device found".
I am pretty confused since the boot options are not as simple as I used to. There are several options for this. I hope some one expert could check the settings and help me out a bit to get the appropriate settings to run ubuntu.
